1. The albino mice were used for this study. The Golgi apparatus in the cells of the epididymis and the vas deferens of normal, starved, and refed animals were studied.2. The amount of the Golgi elements can be maintained by feeding, not only by the sex hormone.3. The Golgi apparatus may be regarded as a product of food assimilation, not a definite cell organ.4. It is suggested that the Golgi apparatus has similar organ with that of mitochondria and secretion granules, but with different quantity of lipoids.

Since the beginning of the last half century, the science of hydrology through successive steps of development has advanced to the realm of quantitative analysis. Engineers employed empirical methods to compute river discharges from precipitation data in answer to the ever-increasing demands made upon hydrologic analyses for engineering works. Yet for the phenomena of conflux of flows from precipitations, there exist only meager and fragmental quantitative analyses, without, so far, a systematic study of their underlying theories recorded in literature. On account of this, the progress of hydrology in respect to theory as well as to prac- tice has been retarded. By means of hydrodynamic analysis, the author has tentatively made an approach to the establishment of such a scheme of theories, in which he divided the rainfall-runoff phenomena into three parts for separate analyses, i. e., the occurrence of runoff due to rainfall at a surface point, the surface flow, and. the conflux of channel flows. This paper is devoted to the first part, which is, in essence, an analysis of the basic hydrologic phenomena. The theories thus established may be used as a guide for various hydrologic analyses in practice, may be based upon to examine the validity of various methods of hydrologic calculations, and may be further used to develop an approximate yet rational method for computing discharges from precipitation data. In this paper, the author proposes a scheme of underlying theories for analyzing the hydrograph of surface flow due to rainfall at a point, in which the essence of basic hydrologic phenomena is revealed, and this is accompanied with calculations of an example. In the earlier years, R. E. Horton established a theory of correlations of rainfall and runoff from small drainage basins by analyzing the data of Homer's sprinkler experiments. Thereafter, researchers basing upon his theories and methods analyzed the relations between rainfall and runoff by sprinkler experiments or data from natural areas. On account of the fact that Horton's analysis does not begin with an accurate hydrodynamical viewpoint, problems are bound to arise in practice due to defects in the underlying theories. Shortcomings of Homer's analysis on the basis of the author's theories are pointed out and the practical value of sprinkler experiments estimated. A method proposed by E. V. Bodakoff for computing discharges due to storms on small basins has raised wide discussions among the Soviet scholars, many of whom hold different views. The author hereby points out the main shortcomings of Bodakoff's method, and gives a numerical example with results compared with those computed by the author's method, thus showing the limitations of Bodakoff's method in practical applications.

半世紀來,水文学在發展的过程中已進入了定量分析的途徑;工程師們曾用各种經驗性的方法依據降水的资料推演河槽裹水流的現象,以应各种工程建設对於水文分析的要求。但是对於降水集流的过程始終祇有一些零星、片面的数值分析,没有一套完整的理論系統,因此阻碍着水文学在理論与应用方面的發展。作者曾用流体力学的分析法初步建立了降水集流的理論系統,把降水集流的过程分為三個階段:雨降地面逕流的產生、地面流、槽流之滙集,分别予以分析。本文便是其中第一階段,亦即最基本水文現象的分析。这些建立了的理論可以用為指導各种水文分析的南針,用為評論各种水文計算法的依據,並可用以創造一种近似而合理的方法,从降水資料推算逕流資料。本文中作者貢献一套理論,以分析地面點上降雨產生逕流的过程,揭發了基本水文現象的本質,最後並列舉实例的計算。早年郝登(R.E.Horton)曾依據郝納(W.W.Homer)的地面流实驗資料建立了一套在小地域內降水和逕流關係之理論,其後学者們根據他的理論和方法,用人工降雨法或流域資料实測法來確定降水和逕流間的關係。郝登的分析並没有从準確的動力学观點出發。在实際分析中發生了欠缺理論基礎的根本問題。这方面作者持着不同的意見。本文中根...

During 1955 and 1956 the pine barkbeetle, Myelophilus Piniperda L., seriously injured pine trees on the hills near by Kiang-Kan section at Hangchow, where the pine logs (firewoods)were piled for a considerable time before selling out. Most of the logs came down from Chien Teh (建德) and Zueng-An (淳安) along the Tsiang Tang River and were infested with immense number of the barkbeetle larvae. Results of study by the writers indicated that the serious infestation of pine shoots was due to spread of the beetles emerged from the piles of log. The pine barkbeetle at Hangchow gave one brood a year, overwintering in pine shoots; up to late March and April they came down to the logs and dead woods in the forest, and made parent galleries between the bark and sapwood. The barkbeetle would take about a month to complete its life cycle. The results of trials and recommendations on control of the pest are given in the following: 1. Separate applications of 25% DDT emulsion, 50% wettable DDT and 6% wettable 666 on the pine logs at a rate of 1:100 dilution still gave 68%, 82% and 66% mortalities respectively on the 20th day. Therefore it was suggested that spraying any one of the above mentioned chemicals three times at 20-day intervals from late April to end of June would kill the emerged beetles. 2. To control the beetles in the pine shoots with 1: 60—1: 100 dilution of 6% wettable 666 was quite promising. 3. Flaming the pine logs or dead woods in April or May (the breeding period of the barkbeetles) for 2 minutes gave 100% mortality. Putting trap trunks in the forest and removering barks before transportation at Chien Teh and Zueng An were suggested.

1.松小蠹虫在杭州地区猖獗成災,主要是由于从錢塘江上游远來的松柴,攜带了大量的松小蠹虫幼虫而造成的;因此若能在松柴產地剝掉樹皮后,再行运輸是最有效的防治措施。2.根据初步观察此虫在杭州一年發生一代,新成虫在5月下旬到9月間为害当年生松梢;越冬成虫从3月下旬起离开越冬松梢,蛀進二年生松梢的梢端取食,并蛀入半枯死樹和衰老樹樹干或柴堆樹皮下產卵。3.为歼滅杭州地区松小蠹虫,根据試驗結果我們認为可采取下列几个措施:(1)自錢塘江上游运來的松柴在成虫未羽化前,進行噴藥,用1:100的25%DDT乳剂、50%可湿性DDT或6%可湿性666,每隔20天噴藥1次,以殺死羽化的成虫。(2)冬季1,2月间砍伐衰老松樹,在山区設置餌木誘集成虫產卵,然后集中处理,進行噴藥或燒灼。(3)新成虫的羽化盛期开始时,在松樹上噴射60—100倍的可湿性666液,毒殺为害枝梢的成虫以保护松樹生長。
