Tung-Kuo pears were stored in cellar storage according to the method used by the fruit growers in Lanchow. The fruits were subjected to different pre-storage treatments in attempting to minimize the loss from decay during the storage period. Effects of these treatments on the physiological activities and the dessert quality of the fruit were also determined. It was found that wrapping with unoiled paper and disinfection with 5% borax solution resulted in a reduction in decay to 53% and 52% of the control respectively during the cella-storage period, a combination of these two treatments further reduced the percentage of decay to as low as 39% of the control. Additional benefits from wrapping were also noted, these were:(1)lower intensity of respiration of the fruit:,(2)higher content of total soluble solids in the fruit,(3)slower ratt to fruit weight loss during the storage period, and(4)better appearance and dessert quality of the fruit. Sweating of the pears before storage not only reduced the loss from decay, but also improved the quality of the fruit. The results confirm the belief of the growers that sweating process is a necessary pre-storage treatment in cellar storage of Tung-Kuo pears.

我们按照兰州果农常用的方法将冬果梨贮藏在地窖里,在贮藏前将果实分别用不同方法加以处理,藉以减低它们在贮藏期间的腐烂损失,同时还比较了不同处理方法对于果实的生理与品质的影响。利用包纸或用5%硼砂溶液消毒的方法可分别使果实在贮藏期间的腐烂率减少到相当于对照的53%与52%。兼用包纸与消毒两种处理可使果实腐烂率降低到对照的39%。包纸的果实还具有其他优点,如(1)果实的呼吸强度较低,(2)可溶性固形物含量较高,(3)果实在贮藏期重量的损失较慢,(4)果实的外观美丽品质优良等。梨果在送入地窖之前先经过一次发汗过程不仅可以使腐烂率减低而且还可以改善果实的品质。达些结果充分证明了一般果农关于发汗是冬果梨贮藏前的必要过程这一经验的正确性。

(Consisting of two articles, the first one was published in 1938 in the Singchow Semi-monthly Singapore, the second is a much more detailed one written in 1957. Followingis a general sketch of both the two articles.) Ⅰ. What is the Malayan Stock? In common sense, Malayan stock means the Malayan race or Brown race, which isone of the five human races of the world. The classic method of the classification ofhuman races according to their skin colour gave the Malayans the pseudo-scientific name"Brown race" which has made the ethnic position of the Malayans as well as the ethnicrelationship between the Malayans and the other related peoples unclear scientifically. Therecent anthropological studies revealed the close ethnic relation between the brown raceand the yellow race, hence the Malayan stock is regarded as one branch of the Mongo-loids and given a new term "Oceanic Mongoloid". The Malayan stock now stands closelywith its two brothers the Northern Mongoloid and the Southern Mongoloid. The term "Malayans" is used here in its broader meaning which includes all thepeoples in Malaysia with a physical characteristics mostly of yellowish-brown colour.brachycephalie (broad) head form, black and straight hair, scanty beard, Malayan eye.medium stature and speaking branches of Malayo-Polynesian language which is agglutina-tive in its nature. Scientifically, both the "proto-Malays" and the "deutero-Malays", orboth the "true Malays" (Orang Malayu) and the other Malayans outside of it are to beconsidered here as the Malayan stock. Generally speaking, largest part of the peoplesliving in Malaya, Indonesia, Philippines and other islands bear this common name inscientific sense. Within the country of Indonesia the term Indonesians is most usuallyused, but in this article, the Indonesians is also included in the term Malayan stockbecause the latter is larger in its scope and more generally used in science. The Malayan stock is not a pure, single race but one of many elements intermixedtogether. The first element is the Oceanic Mongoloid which came from the north, pro-bable Chinese continent, its physical characteristics survived are the black, straight hair,broad head, yellowish-brown colour, medium stature and certain degree of Mongolian eye(narrow eye with Mongolian fold which covers the upper eye-lid). The second elementis the Indonesian stock, (This is used in scientific, narrower meaning instead of thatused in common sense) and early branch of the Caucasian race, originated in westernAsia and migrated eastward to Malaysia through Indo-China; it gives the present people the physical characteristics of Malayan eye, (broad eye without Mongolian fold hence theeye-lashes and a concave line on the eye-lid can be seen clearly) a certain degree of doli-chocephalie (long) head together with the agglutinative Malayo-Polynesian language. Thethird element is the Oceanic Negroid whose part contributed to the Malayans is not solarge that it still has pure descendants in present day viz. the Negritoes and the Papuans;while the fourth element is the Veddas came from India. The third and fourth one arri-ved earliest in probably Palaeolithic age, but played no important role in ethnic composi-tion of the Malayan stock because of their small number in population. The second onereached Malaysia after the above two probably in early period of Neolithic age, while thefirst one arrived latest in later period of Neolithic age. Though later in time, the OceanicMongoloids and Indonesians came in large numbers hence they formed the two principalelements of the Malayan stock. As the outcome of the intermixing of blood there appea-red a great mixed racial stock which looks different from its original elements, conseq-uently the original names are no longer suitable to be used. The term Indonesian is usedhere in its original meaning which is different from that of the so-called "Indonesians"in present day use. The mixed stock is no more called Indonesian but Malayan stock inthis article. Ⅱ. Is there Any Connection Between the Malayan Stock and the Ancient Peoples in Southern China? The cradle of the mix-blooded Malayan stock may be in the meeting point of the twoprincipal elements. Indo-China, a necessary meeting point on their ways, was naturally thecradle of the Malayan stock. From Indo-China floods of racial migration appeared fromtime to time and peopled the islands of Malaysia from west to east. As the Oceanic Mongoloid might be originated in the east Asia continent and mig-rated southward to Indo-China, naturally there must be a time in which they lived insouthern China as well as in Indo-China. Furthermore, the ancient peoples in SouthernChina consisted of various aboriginal tribes different from the Chinese Proper, it seemsnot very unreasonable to suggest that besides the Mongoloids there might existed too acertain primitive branch of Caucasian race or even Negroid race in southern China eventhough in small number before the Chinese Proper migrated southward. Possessing theability of migrating southward by the difficult way of water, why the Indonesians couldor would not proceed further eastward from Indo-China by an easier way of land tosouthern China During or preceding Chow dynasty (before 250 B. C.) in the coastal regions of sout-hern China (Chekiang, Fukien, Kwangtung, Kiangsi, Kwangsi provinces) there existedan ancient aboriginal stock with the name of "Yueh" which was looked by the Chineseproper as a different race because they lived in different way, followed their own queerhabits and customs and spoke in a different tongue. This stock was indeed more strangethan the other aboriginal stocks in southem China. The formation of such a stock mightbe the outcome of blending of the Mongoloids arrived from the north with some other peoples came from the southwest. As there really existed a different people-the In-donesians-migrated from the west and the blending of the two races-the Indonesiansand the Mongoloids-was actually taking place in Indo-China, it is far from impossiblethat such a phenomenon might extend and appear also in southem China. Being theproduct of mixing blood of the two principal races-the Mongoloids and the Indonesians-the Yueh stock might be in the same condition as the Malayan. If the intermixing of the Mongoloids with the Indonesians really took place in sout-hern China, the ancient people Yueh then was the brother of the Malayan stock. At thebeginning they might resemble to each other, but in later days both of them lived indifferent places and mixed with more other peoples, hence appeared also different fromeach other. Since the Chin dynasty (220 B. C.) the Yueh stock began to be assimilatedby the Chinese Proper from the north; the process of assimilation of culture and theblending of blood reached its conclusion in about 6th century. Later on no survivor ofYueh stock with pure blood or tribal name ever appeared in China. Their mix-bloodedoffspring, however, have existed up to present time as the population of the southeastcoastal region viz. Chekiang, Fukien, Kwangtung Provinces. Ⅲ. Three Evidences From the historical and geographical point of view, we get the above hypothesis ofthe ethnical Connection between the Malayan and the Yueh stock in southern China. Ifthis is true there must be, between them, physical and cultural resemblances which aresound enough as the evidence. Three sorts of facts, as I seek, may do this service: (1) Resemblances in Physical Characteristics--Though there is still no enoughamount of prehistoric skeletons of both the Indonesians and the Oceanic Mongoloidsunearthed in Malaysia and southern China for scientific research, the Iiving offsprings ofboth the two ancient races may give us some hints about this question,. It is often observedthat the physical characteristics of the southern Chinese of present day are different insome respects from the northern ones although basically they are of the same type viz.the Chinese type. Among them, the peoples of Kwangtung and Fukien have espicially adifferent appearence: Firstly, the eyes of them are broader and less in degree of Mongolian fold on theupper eye-lid. The eye of this type is the medium form between the Mongolian and theMalayan eye, and may be called Half-Malayan eye. Generally most of the Mongol Properand the northern Chinese have the Mongoian eye, while the Malayans have the Malayaneye. The intermediate eye suggests that the human group possessing it must be the mixedblood of the two kinds of peoples with these two sorts of eyes. Wherefrom did the sout-hern Chinese get the half-Malayan eye? Unless they had as one part of their compositeelement a sort of people with Malayan eyes, it is quite impossible to explain the derivationof this eye form. this eye form, therefore, tells us that the southern Chinese, especiallythat of Kwangtung, Fukien and perhaps Chekiang provinces had as one part of theirancestors a people with Malayan eyes. The Malayans may get their malayan eye from the Indoncsians, because the Indonesians belong to the Caucasian race whose eye is calledEuropean eye which is the same as the Malayan one. In fact, the European eye formappeared on the Malayan face is called Malayan eye. The eyes of the southern Chinesetherefore might he derived from the same way as the Malayans. Secondly, the stature of the southern Chinese especially those of Kwangtung andFukien is generally lower than that of the northern Chinese; while compared with theMalayans, they are nearly the same with each other. Thirdly, some of the faces of the southern Chinese looks different from the northernones but appears resembling the Malayans. The Southerns have a shorter face while thenortherners have a longer one. As the physical characteristics of both the southem Chinese and the Malayans resem-bling each other, it is hardly possible to distinguish some Chinese in Malayan costumesand vice versa. The Chinese new comers in Malaysia are often astonished to find thatthe so-called strangers or foreigners viz. the Malayans, look quite like themselves in theirphysical respect. Sometimes it is not easy too for the Europeans to distinguish betweenthe Chinese and the Malayans, because most of the Chinese immigrated to Malaysiancountries were from the southeastern coastal regions which was the home country of theancient Yueh people. (2) Resemblances in Early Cultural Respects--Of course the cultural life ofthe southern Chinese and the Malayans in present day are different to each other, butthe historical records about the ancient Yueh people reveal that the Yueh stock had intheir material life, social customs and languages some points suggesting the connectionwith the Malayans. These may be enumerated as the following: 1, Hair cutting: The ancient northern Chinese never cut their hair, the Miao stockbound their hair too, only the Yueh people was noted for their hair cutting. The primitivebranches of the present Malayan also cut their hair, the early Malayans probably had thiscustom in ancient times too. 2, Tattooing: The Yueh was also well-known for their tattooing which made themlook quite wonderful to the other Chinese, The Malayans of today still have kept thiscustom in Borneo, Philippines etc. 3, Snake worship: The Yueh worshipped the snakes and those in Fukien even tookthe snake as their totem. The aborigines in Taiwan province, which belong to Malayanstock too, still preserve the remnant of such belief, Snake worship is not unknown tothe Malayans in Malaysia too. 4, Pile-house: At present the pile-houses of the Malayans is quite well-known forits specialty; such form of building, however, was also adopted by the ancient southernChinese because it is recorded that the Yueh lived in nest, and the later southern peopleslived actually in the pile-houses which was called "kan-lan". 5, Naked foot: The Yueh's naked foot custom was also noted in ancient times.while the Malayans in history also kept their feet naked even though they were officersin the kings courts. 6, Agglutinative language: The Yueh spoke in a different and queer tongue fromthe Chinese Proper and even the other peoples in ancient times, the translation of Yuehwords gave the Chinese Proper a hard question; to denote the sound of a Yueh word,one Chinese word is not enough, while two or three words sound too much. Thiscondition suggests that though the Chinese language was isolating in its nature, that ofthe Yueh might belong to agglutinative one, because one agglutinative word usually pro-nounces just like two or more isolating words connected. Heine-Geldern and other scholarealso suggested that the Malayo-Polynesian or Austro-Asiatic language was originated inthe continent. The present south-eastern Chinese still speak in different dialects whichproves that the ancient Yueh language was quite strange to the northern Chinese. Thedifficulty to compare the ancient Yueh language with the Malayan one lies in the factthat both the present tongues used by the modern Malayans and the southern Chinesehave been changed by nearly two thousand years' assimilation with other languages. (3) Resemblances of Prehistoric Remains--Before the prehistoric archaeologicaldiscoveries took place in southern China, the question of the derivation or origin of someprehistoric objects in malaysia and even Polynesia had been very hard to be solved. Poly-nesia is famous for one special type of stone implements viz. the tanged adze or steppedadze, the origin of it was traced to that unearthed in Philippines; the derivation of thestepped adze of Philippines, however, was also very hard to be traced. Since about 1930the prehistoric findings began to take place in southern Chinese continent. the newmaterials enable the old questions easier to be solved. The prehistoric remains are difte-rent to those found in northern China, the latter consists of the painted pottery, blackpottery, thick stone axe, holed stone axe etc., whilc the former consists of the pressedgeometric-designed pettery, the stepped adze, the shouldered axe etc.. Strange to say thatthe southern prehistoric objects of China really resemble those of Malaysia and evenPolynesia. These objects may be pointed as the following: 1, Stepped stone adze: Stepped adze is found in large numbers in the south-easternregions viz. Fukien, Kwangtung, Chekiang, Kiangsi, Kiangsu etc., but appears veryrare in the eastern part of northern China and is entirely unknown in the western partof it. The shape suggests that it was developed in three stages just like that of Phi-lippines and Polynesia. Furthermore, the stepped adze of primary and intermediate stagesappeared more in number in south-eastern China, while that of the higher stage appearedmore in Philippines and Polynesia; such a condition reveals that the stepped adze of Phi-lippines and Polynesia was derived from south-eastern China. The way of transmigrationof the stepped adze is probably through Taiwan, Philippines and other islands. 2, Shouldered stone axe: The shouldered axe appeared in Indo-China. Malay pe-ninsula, Philippines etc., but was not found in the intermediate islands viz Sumatra,Java etc.. It was unearthed in Taiwan and Hainan islands too. In the southern part ofthe Chinese continent it appeared less in number but more will be found in future. Inthe north-eastern China very rare was obtaine(?) too. The shouldered axe might be ori-ginated in Indo-China and then spreaded eastward to the south-eastern coastal region of Chinese continent, therefrom it crossed the sea and arrived in Philippines through Tai-wan island, On the way a northward route led it to the north-eastern region. Anotherroute led it southward to Malay Peninsula. Shouldered axe is also an object of evidenceshowing the relation of the Malayans and the southern Chinese, because the prehistoricpeoples in Indo-China was the Malayans instead of the Annamese etc.. 3, Pressed geometric-designed pottery: In southern, especially south-eastern China,the prehistoric pottery was that with geometric designs pressed with pottery prints, thisis quite different to the painted pottery of north-western China and the black pottery ofnorth-eastern China. In Malaysia and Indo-China the prehistoric potteries found resembleto that of south China, some of the shape of the potteries as well as the pressed designsare quite like each other. Some potteries of this type were actuaily found in Indo-China,Java and Sulawesi, which are comparable with that of south China. This kind of potteryalso suggests the prehistoric connection between Malayans and the southern Chinese. Ⅳ. Conclusions (1) The Malayan stock is a mixed blood of chiefly the Oceanic Mongoloid raceand the Indonesians which is an early branch of the Caucasian race. These two raceshave been blended to such a degree that a new stock appeared which is called the Ma-Jayan stock, and the two elements have no more pure offsprings survived. The presentMalayans show more Mongolian physical features than the Indonesian ones, hencs it istaken as a branch of Mongoloids. (2) The Oceanic Mongoloid came from southern China, hence these should beethnic connection. between the Malayans and the ancient southern Chinese. Moreover,the other two elements of the Malayans, the Indonesians and the Negritoes probablyalso arrived and lived in southern China earlier than the Mongoloids and became partof the ethnical elements of the southern Chinese in later days, therefore the Malayansand the southern Chinese may have the same ethnical element. (3) The present southern Chinese, especially the south-eastern ones have some phy-sical characteristics like the Malayans, their ancestor Yueh stock had some customs andlanguage showing some resemblances to the Malayans, finally, the prehistoric discoveriesalso show the relationship between these two races. (4) The processes of the formation of the Malayan stock might proceeded in Indo-China and southern China. Since Neolithic age the Malayans migrated step by step toMalaysian islands, while those remained in Indo-China and southern China were assimi-lated by the Chinese Proper, Annamese, Siamese and Burmese. The ancient Yueh stockin southern China might have nearly the same ethnic composition as the Malayans, butwas assimilated by the Chinese Proper since two thousand years ago. (5) There might be two routes of southward migration of the Malayans. The firstand principal one was the west route which started from Indo-China, penetrated Suma-tra, Java and Borneo, and finally reached Philippines; the evidences are the pressedgeometric designed pottery and the shouldered axe. The second was the east route whichstarted from the south-eastern coast of Chinese continent, passed Taiwan and other islets,finally reached Philippines, Sulawesi and eastern Borneo. The stepped adze, the shoul-dered axe, and the pressed geometric-designed pottery are the evidences of this

This paper attempts to answer the following two questions: (1) Is it possible to derive the law of distribution of hydrological frequency theoretically(2) What type of distribution curve should be adopted as the model of hydrological frequency curve and how to determine their parameters? The results obtained may be summarized as follows: 1. Hydrological phenomena are time series with concealed periodic fluctuations. The results from statistical analysis based upon the current assumption that hydrological phenomena are independent stochastic variables should be accepted with due considerations. 2. In view of the regional nature of hydrological phenomena, the current parctice of analyzing samples taking from a single station only is, in effect, to narrow the sampling field arbitrarily from a larger area to a point, thus reducing the accuracy of the statistical results. Hence, the synthetic utilization of the data of all stations within the hydrologically homo- geneous region is an important measure to increase the accuracy of statistical analysis. 3. The belief that the flood frequency obeys the binomial theorem or Poisson's theorem is but to mix up the priori with the empirical probability problem. The binomial theorem, being a powerful weapon to deal with the problems of priori probability, has not been adquately and properly utilized in the hydrologieal frequency analysis. 4. Analyses have been made of the nature of distribution of shydrologieal series on the basis of Kaptyen's derivation of the skew distribution, which indicate: (1) That the theoretical interpretation of the log-probability law of the hydrologic phenomena by V. T. Chow is not sound; (2) that hydrologic phenomena being results of very complicated meteorological and hydrological processes, it is impossible to derive theoretically the law of distribution for the hydrological series. 5. The view that the flood frequency obeys the Gumbel's distribution is theoretically not sound and also not verified by actual data. 6. According to the nature of the mathematical treatments applied, the method of description of the empirical probability can be classified into three systems: (1) The methods of the generalization of the characteristic factors of the distributions, such as Pearson's curves, Goodrich's curves, etc.; (2) The methods of the modification of a fundamental distribution by series and polynomials, such as Gram-Charlier curves. curves, etc.; (3) The methods of transformed functions, such as the log-probability law, curves, etc. It should be remarked that not only Pearson's and Goodrich's curves are frequency curves of empirical nature, but even the theoretical laws, such as the normal law and the log-probability law, will be aceepted as curves of empirical nature, when used as models for empirical probability problem. 7. Hydrological frequency analysis should not be mystified and made absolute. Instead of free selections, the models of hydrological frequency curve should be uniquely selected and specified. Statistical parameters should be determined not solely by the short period data of single station, but also by the synthetic utilization of the data of possible more stations. 8. It is recommended that one of the two types of distribution, i.e. the log-normal frequency curve with both sides limited and the Pearson's type Ⅲ curve, may be selected as unified models. The author suggests that the K-value corresponding to recurrence intervals of say 10~4, 10~5, or 10~6 years may be selected as the upper and lower limits for the log-normal curve. For Pearson's type III curves, C_s should be treated not as independent but as dependent variables of C_v. 9. The proper way to select and determine the model frequency curve is to see whether it fits well with the actual data of grouped stations (stations to be grouped by regions for rainfall data and by C_v for runoff data) and the reasonableness of the extrapolating part. 10. Suggestions on the method of determination of x and C_v: For point rainfall, iso-x map may be utilized, and the mean C_v for each hydrologicregion may be adopted in order to minimize the errors from single stations and to avoid the discrepancies in results obtained from the same region. With regard to flood frequency analysis, flood mark reconnaissance must be utilized to determine the magnitude and the recurrence interval of the unusual flood. The x and C_v values of the floods and runoffs of hydrologically similiar river basins may be compared. Besides, the reasonableness of the results of frequency calculations as well as of the statistical parameters adopted therein may be checked by comparing runoffs and point-rainfall values of the same frequency.

我国近期水文频率计算方法的研究工作在选择方法,经验频率公式,参数的误差和利用我国水文资料检验各种频率线型等方面有了一定的成果和实用的结论[1],但是下面两个问题还没有获得解决: (1)能否从机率理论证明水文频率属于何种分布律? (2)水文频率曲线应当采用什么线型?如何确定参数?本文试图解答以上两个问题。本文分析了水文系列的时序性质和区域性质,把机率问题按先验、极限和后验三种基本性质对水文频率问题进行了分析;利用开布屯推导偏态分布的方法分析了水文系列的分布性质,并从而批判了有关水文频率肯定属于对数正态律,耿贝尔极限律或二项式定理等等说法。认为属于后验机率性质的水文频率,不能从机率理论证明它属于何种分布律。最后提出联合利用各站水文资料来选择线型和确定参数的方法,并建议在两端有限对数正态和皮尔逊Ⅲ型两种线型中选择一种作为统一采用的线型,对两端有限曲线提出了简易可行的确定上下极限的方法,对皮尔逊Ⅲ型曲线认为应该把Cs作Cv的倚变参数。
