The city of Lanehow lies in the central part of China in latitude approximate 36°03′north, longitude 103°57'east, at elevation 1,508.53 M. Kowlanshan, the area surveyed, being one of the many loess plateau hills surrounding Lanchow, situates on the southeastern suburb of the city. Physiographically, the area is a part of the dissected loess plateau with an altitude of 1,508-2100 M. Owing to the influences of the geographical condition and high elevation, the climate of this area is of continental climatic type. The mean annual precipitation is 338.6mm. with 61.1% of it falling in June, July and August, annual mean temperature, 6.9℃., relative humidity, 58%, annual total evaporation, 3,571mm. and annual mean wind velocity 5.8m/sec. The upper portion of the hill is entirely covered with a thick layer of loess and underneath lies the red earth of the tertiary period. As a result of that, soils in the area surveyed, which has been developed from the loess, is high in calcium content. It belongs to the chestnut soil type with a PH value between 7.6 and 8.1. The vegetation of this area shows the following ecological characteristics: 1) The specific composition of the plant is rather scanty with about. 124 speeies belonging to 93 genera and 41 families; 2) The vegetation bears a simple physiognomy. No natural growth arbor been found in the whole area during the period of investigation, though a few species of cultivated trees are found and the vegetation is mainly composed of semi-frutexes and herbages; 3) Most of the essential species distributing here express distinct xeromorphic structures and many of them are typical components of the vegetation of the steppe and semi-dessect, such as Caragana spp., Hololachne soongarica Ehrenb., Artemisia spp., Chrysanthemum neofruticulosum Ledeb., Stipa spp. Achnatherum splendens Ohwi. and so on. Four plant associations are found in this area. Three of them distribute on the Dorthern slope and one on the southern slope of the hill. They are described as follow: Ⅰ. Chenupodium album+Artemisia annua+Elymus dasystachys Association. The distribution of this association is limited to the erosion valleys situating on the piedmont belt of the northern slope at an elevation between 1, 510 and 1, 560 M., where the edaphic condition is marked by high soil moisture content. The climatic features are of low light intencity with short duration of daily sunshine, high relative humidity and low wind velocity. Three hygrophilous and shade-loving species are the main constituents of this association. They are chenopodium album L., Artemisia annua L., and Elymus dasystachys Trin. Other herbaceous plants are Chenopodium glaucum L.. Sonchus aler- aceus L., Xanthium strumarium L., Polygonum amphibium L., P. aviculare L. etc. A few shrubs are present in the association. They are Lycium chinensis Mill., Lonicera heteroloba Batal. and Lonicera ferdinandi Fr. Ⅱ. Artemisia pectinata Association. The Artemisia pectinata Association occurs on the piedmont belt of the northern slope at an elevation varying from 1510 to 1580 M. It occupies the open slope with gradients under 15°. The climatic conditions, in speaking of the northern slope, are rather high in temperature, strong light intencity, low relative humidity and low wind velocity. The projective total cover-degree is about 50% and Artemisia pectinata Pall. appears to be the dominant species in the association. Besides, there are species of thermophilous and heliophilous plants such as Salsola kali L., S. arachnoides‘Moq’. Kung, Cymbaria mongolica Maxim., Artemisia capillaris Thumb., Aster altaicus willd., chrysanthemum neofruticulosum Ledeb., which are frequently scattered among the dominant plants. Plants growing in this association, are all below 10 cm. in height. They give an appearence of open association. Ⅲ. Chrysanthemum neofruticulosum+Artemisia sacrorum var. latiloba—Polytrichum sp. Association. This association, being the largest one in the surveyed area, appears on the northern slope, where it occupies the space ranging from altitude 1,580M. to the top of the hill,2,100M, above the sea level. Soil is of chestnut soil type with a PH value of 8. 0—8. 1.The soil moisture content varies between 6.0 and 7.4%(layer above 60 cm.). In vertical structure, the association consists of two strata. They are described below: Stratum Ⅰ: This stratum includes all shrubs, semi-frutexes and herbages which are taller than 10 cm. in height. Among the plants found in this stratum, chrysanthemum neofruticulosum Ledeb. and Artemisia sacrorum var. latiloba Ledeb. are dominant species and Stipa Bungeana Trin. is the subdominant one. Other species one may frequently meet with are Allium subangulatum Rag., Saussurea nigrescens Maxim., Peganumharmala L., Astragalus dahuricus Dc., Potentilla multifida L., Linum perenne L., Car-agana frutex K. Koch. etc. They spread widely in almost all over the association. Stratum Ⅱ: This stratum is composed of those species less than 10 cm. in height, forming the ground flora of the association. Polytrichum sp. and Lichens are the essential plants in the stratum. One may occasionlly find species of Plantago Lessingii and Gentiana squarrosa Ledeb. growing among those main constituents. The underground stratification of the association has also been studied during the time of surveying. IV. Stipa Bungeana+Aster altaicus+Chrysanthemum neofruticulosum Association. This association distributes on the entire southern slope except the portions tilled for agriculture purposes. The striking local ecological conditions of this association are strong light intensity with long duration of daily sunshine, high temperature, low relative humidity and extremely low in soil moisture content which ranges between 2. 7 and 4. 0% (the layer above 60cm.). On account of the severe destruction of natural vegetation by man and cattle in the past years, the degree of soil erosion is serious throughout the slope where the association locates. The PH value of the soils is 7.4-76. The polydominant plants in this association are Stipa Bungeana Trin., Aster altaicus Willd. and Chrysanthemum neofruticulosum Ledeb. They are quite adaptable to the drought condition of the environment and distribute widely in the association. Besides, other xerophilous or drought resistant plants are frequently met, such as Hololachne soongarica Ehrenb., Linum perenne L., Astranalus dahuricus Dc., Peganum harmala L., Artemisia sacrorum var. latiloba Ledeb., Artemisia capillaris Thumb., Incarvillea Iutea Bur.&Franch., Kochia scoparia Schred. etc. They dispersely grow in the association. In addition to the frequent species mentioned above, Salsola ruthenica Iljin. and S. arachnoides‘Moq’. Kung form seperately micro-associations lying scatterly on the slope. No ground flora stratum may be found and the association shows no above ground stratification. The projective total cover-degree of this association is only about 25-30%. Owing to the difference in the aspects of the northern and sourthern slopes, the climatic and edaphic conditions vary remarkable. Therefore, the vegetation of the surveyed area shows distinctions in distribution, floristic composition, physiognomy, structure, condition in growth and development of plants in the association of different slopes. Taking the floristic composition for example, the following species are entirely absent in the association of the northern slope, yet they are main components on the southern one: Pappophorum brachystachyum Taub. et Spach, Thermopsis lanceolata R. Br., Caragana spinosa Dc., Stellera chamaejasme L., Hololachne soongarica Ehrenb., Nitraria schoberi L., Pennisetum flaccidum Griseb. Differences in elevation also induce striking changes in climatic and edaphic con-ditions especially in aspects of air temperature, relative humidity and soil moisture content. All these gives great influence to the alterations either in quantity or in quality of each species distributing along the northern slope of the area. Following the seasonal change, the physiognomy of the associations expresses sucession of seasonal aspect. Vernal, aestival and autumnal aspects have been observed and recorded.

Association) 本群丛包括皋兰山北坡自海拔1580米以上一直至山顶(海拔2100米)的全部地段,为调查区内分布面积最广的群丛。其生态环境是阳光弱、日照时间短、蒸发量小、气温低;土镶为栗钙土,PH值在8.0—8.1左右,土壤风干含水量为5.2—5.6%。群丛在垂直结构上,可分为两层:第一层包括高度在10厘米以上的灌木、半灌木与草本植物,而以小黄菊和供蒿最占优势。本氏羽茅则为本属中的亚优势种。常见植物尚有野葱、青木香(Saussurea nigrescens Maxim.)、骆驼蓬、达乌里紫云英,多裂委陵菜、宿根亚麻、木锦鸡儿(Caragana frutex K. Koch.)等。第二层为地被层,主要由藓类和地衣所组成。此外,偶尔出现细叶车前(Plantago Lessingii)与鳞叶龙胆(Gentiana squarrosa Ledeb.)铺地生长。群丛总复盖度约为67%。 4.本氏羽茅+阿尔泰紫菀+小黄菊群丛(Stipa Bungeana+Aster altaicus+Chrysanthemum neofruticulosum Association) 这一群丛占皋兰山南坡除农田以外的全部地区。其气候与土壤条件,可归纳为下:日晒强烈、日照时间长、气温高;人为对自然植被破坏强烈,表土冲刷现象异常严重。土壤水分含量甚低,仅占风干重的1.88—3.41%,pH值为7.4—7.6。本氏羽茅、阿尔泰紫菀与小黄菊为群丛中的主要种类。它们对于干旱的环境均具有强大的适应力。其他常见植物有红砂、宿根亚麻、达乌里紫云英、骆驼蓬、供蒿、茵陈蒿、黄角蒿(Incarvillea lutea Bur.&Franch.)地肤等抗旱或耐旱种类。苏联猪毛菜(Salsola rutheniea Iljin)和灰蓬,常各成单纯小群丛,出现于山坡间。本群丛中缺地被层,无地上成层现象。群丛总复盖度仅为25—30%。由于南北坡取向不同所引起气候与土壤因子的变化,调查区植物群落,在分布、结构、外貌、种类成分及生长发育状况上,也随着发生很大的差异。海拔高度的改变,对气温、相对湿度,土温及土壤水分状况的影晌,也明显地反映在群落中各个种间的数量比例关系上。随着季节的更换,群落中的种类成分,表现出比较显著的季相演替关系。作者等曾作北坡群丛春、夏和秋三季季相的观察与纪录。

The general histological structure is fundamentally similar to that of the skin of frog (Pl. Ⅰ, Fig. 1). In the superficial layer of the dermis there are large and conspicuous round masses, which are akin to the sieve layer (Siebschicht of Kastschenko) both in appearance and in staining reaction (Pl. Ⅰ, Fig. 1; Pl. Ⅳ, Fig. 6). To our knowledge, the origin and function of these masses as well as the sieve layer are still obscure.According to the living habit, the life of the toad during the year can be divided into three seasons: namely, the hibernating, the breeding and the post-breeding season.In the hibernating season the epidermis reaches its maximal thickness due to increase in cell layer as well as in cell size. Cell division is rare in this season. The superficial layer is evenly cornified and the intensity of comification is intermediate, being stronger than that in the breeding season but less than that in the post-breeding season. This horny layer is connected intimately with the layer below and shows no sign of moulting (Pl.Ⅰ, Fig. 1; Pl. Ⅱ, Fig. 1). The flask-cells of Pfitzner (nucous cells of Legdig or goblet cells of Schultze) are very rare and when present, they are not fully differentiated from the ordinary epidermal cells. Melanophores are greatly expanded both in the epidermis and in the dermis (Pl.Ⅳ, Figs. 4, 3). Dermal papillae are tall and prominent (Pl. Ⅱ, Fig. 1).In the breeding season the epidermis is much thinner than that in the hibernating season. Moulting of skin goes on continuously. In association with moulting the flask-cells increase in number and show vigorous activity in secretion (Pl. Ⅱ, Fig, 2). Numerous amitoses are present in the middle and lower layer of the epidermis. At the initiation of the amitotic division a furrow appears at one side of the nucleus, which deepens and finally cuts the nucleus into two. Sometimes two furrows are formed, causing one nucleus to break up into three. A furrow may start at one end of the long diameter of the elliptical nucleus, causing it to split longitudinally into two daughter nuclei (Pl. Ⅰ, Fig, 2). We call this mode of amitosis furrowing amitosis. The usual mode of amitosis in which the nucleus divides by a central constriction could be found also, but cases are very rare. Mitotic figures are very rare. Melanophores are more or less contracted in the epidermis as well as in the dermis (Pl. Ⅱ, Fig. 2).In the post-breeding season the epidermis is intermediate in thickness between those of hibernating and breeding seasons. Due to the dryness on land the certification of the superficial layer is intense. Sometimes there are three layers of highly cornified cells, while in the other seasons this layer is always simple (Pl. Ⅱ, Figs. 3, 4, 5). Both mitosis and amitosis are present (Pl. Ⅱ, Figs. 6, 7). The former is much more in number than the latter. Wandering cells in the dermis penetrate into the epidermis and become epidermal cells (Pl. Ⅲ, Figs. 1, 2, 3). Flask-cells are fewer in number and less in activity than in the breeding season, hence the moulting of skin goes on slowly. All the melanophores are contracted in the form of a black spot (Pl. Ⅱ, Figs. 3, 4, 5). The blood vessels in the epidermis are greatly expanded, and are therefore easily seen (Pl.Ⅳ, Fig. 6).The nuclei of certain epidermal cells send out processes, which penetrate through the cell membrane and move along the intercellular spaces (Pl. Ⅲ, Figs. 4, 6). Sometimes these processes get into the neighboring cells (Pl. Ⅲ, Figs. 7, 8). In still other cases nuclei sued out coarse processes which come into contact with identical processes sent out by nuclei of neighboring cells (Pl. Ⅲ, Fig. 5). So far as we know, such intercellular activity of nuclei of the epidermal cells has not been heretofore repoifted. Its significance probably lies in the transportation of certain substances such as DNA. Nuclei showing this activity stain more intensively with Feulgen.The above description applies to the typical structures in each season. It is found that at the time between two se

蟾蜍皮肤的构造基本上与蛙类相同。只是在蟾蜍的真皮上层除去有筛层而外还有大而圆的物体,在形态及染色反应上与筛层相近似,我们名之为粘液团(因为有粘液反应)。 依大蟾蜍的生活习性,我们把它在一年之中的生活分为三期——冬眠期、生殖期及生殖后期。 冬眠期表皮的厚度增加,层数多,细胞也增大。很少见细胞分裂。表层细胞角化得很均匀,其程度比生殖期略强而比生殖后期为弱。这一层与下面一层连接得很紧密,没有任何脱落的迹象。瓶状细胞很少,如果看到总是处于不太分化的状态,除去它的细胞质比较清明而外,与表皮细胞的差别不大。在表皮与真皮之中色素细胞极度扩张。真皮乳头高而显著。 生殖期表皮比冬眠期薄,脱皮不断迸行。与脱皮相关的瓶状细胞数量增加,并且显现非常强烈的分泌过程。在中层及下层中有许多的无丝分裂。分裂的方式多为陷沟式。一般所见的无丝分裂即核拉长,中间缢缩,然后分开的情形也能见到,不过远比陷沟式为少。有丝分裂很少见到。表皮与真皮中的色素细胞多少有些收缩。 生殖后期表皮的厚度界于冬眠与生殖二期之间。由于陆地的干燥表皮表层细胞角化程度加深。有时表面集聚三层高度角化的细胞,而在其他季节中表层总是一层。有丝分裂与无丝分裂皆有,但前者远比后者为多...

When the tall rigid frames for boat lefting in the Three Gorges were being analysed, we discovered that the so—called method of single distribution of moments can be improved upon as well as a new method of stress determination, namely the method of mean 'stiffness. For the calculation of tall frames, it was found that by means of lhese two methods accurate or approximate results can be obtained quickly and with great ease.In the case of the improved version of single distribution of moment method, a correction coefficient for the stiffness λ is to be used (λ_(AB)=1—C_(AB) C_(BA) μ_(BA), SO λ_(AB)=1—1/4μ_(BA), when the ordinary carrying factor is 1/2 and λ_(AB)=1—μ_(AB), when the oridnary carrying over factor is-1, where μ_(BA) is the ordinary distributing coeffcient). Multiplying the stiffness by this correction coeffcicnt, a set of distributing factors are calculated ( the same as those obtained by T. Y. Lin ). At the same, time, the ordinary carrying over factors are multiplied by the reciprocal of the correction coeffcient (?)/λ, so that a set of new carrying over factors are obtained. In this waY the calculation of new carrying over factors is much simplifted, at the same time the process of single distribution is also much simplified.In the case of the method of mean stiffness, an unsymmetrical multi-—story singlespanned rigid frame is transformed into a symmetrical one by using the mean stiffness instead of those original ones the structure. In this way the frame can then be analysed by means of Shagin (?) basic members and a single distribution with constant shears is crrried out. After this with a few ( once or twice ) simple adjustments, highly accurate results are ensued. This method can also been used for non-symmetrical multi-story and multi-spanned rigid frames as well (?) Vierendecl girders, and will give results to any degree of aocuracy quickly.

在三峽升船机高排架的計算中,我們对力矩一次分配法进行了改进,并研究出一个平均剛度法,这两个方法无論用之于高排架的精確計算或近似計算都是比較簡单而迅速的。改进后的力矩一次分配法是利用剛度修正系数入(λ_(AB)=1—C_(AB)C_(BA)μ_(BA)’当普通傳递系数C是(?)时則λ_(AB)==1—1μ_(BA),当普通傳递系数是—1时则λ_(AB)=1—μ_(BA),式中μ_(BA)是普通分配系数)乘剛度后計算一套分配系数(和林同棪的相同)再利用同样的剛度修正系数的倒数1/λ乘普通傅递系数,即得修正傳递系数,这样就能使修正傳递的系数的計算很簡单而且一次分配的过程也很簡单。平均剛度法是将不对称单跨多层剛架用平均剛度的办法使轉化为对称,从而可利用Шагин基本构件进行无剪力一次分配,再进行次数不多的(1至2次)簡单修正,即可得相当精确的結果,这个方法也可用之于不对称多层多跨剛架和不对称的空腹剛架的计算,迅速得出我們需要的任意精確的结果。
