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...

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。本文中根據作者的理論指出了郝登分析法的癥結所在,並估計了人工降雨实驗法的实用價值之限度。波達闊夫曾建議暴雨逕流之一种計算法,引起了苏联学者的廣泛討論,很多人持有不同的意見。作者於文中指出了波氏等方法發生問題的症結所在;並用实例計算和作者的方法比較,說明了波氏法在实用中的準確限度。

Based on the results of the author's previous study, the Hwang-Ho Valley and its surroundings are devided into seven regions. Various drought relationships between these regions are analyzed in the following three main headings: (1) The chances of drought or flood of any two or more of these regions that may occur at the same time, (2) The possibility of drought or flood of other 6 regions when drought occurs in certain one region, and (3) The intensity of drought between certain stations and the possibility...

Based on the results of the author's previous study, the Hwang-Ho Valley and its surroundings are devided into seven regions. Various drought relationships between these regions are analyzed in the following three main headings: (1) The chances of drought or flood of any two or more of these regions that may occur at the same time, (2) The possibility of drought or flood of other 6 regions when drought occurs in certain one region, and (3) The intensity of drought between certain stations and the possibility of persistence of the drought. Finally it is pointed out that other than the Kiu-Chuan, the drought is most severe in Ho-Pei plain, while Wei-Ho basin, on the opposite, is comparatively the least severe region.

本文在作者“黄河流域干旱初步分析”的基础上将黄河流域分为七区,统计并分析了这些地区旱涝关系。本文主要讨论以下几点:1.黄河流域任两地区(或三个四个地区)同时发生旱涝的机会。2.如果一个地区干旱其他各区发生旱涝的可能性。3.个别地方干旱在程度上的比较,并计算干旱的持续性。最后指出,除了黄河上游的西北方(酒泉),河北平原及其附近地区干旱最为严重,而渭河盆地旱情最轻。

1. Firmiana simplex has been cultivated by our Chinese people in both ancient and modein times for medical use, and for the making of furnitures and musical instruments, as well as ornamental tree.2. The distribution of this plant is wide-spread almost through entire China. According to the writer's observation it grows vigorously and reaches its maximum height in the lower part of the Yangtze basin.3. In 1929 Yen states that sex differentiation of Firmiana simplex might be due to the fact of nutrition,...

1. Firmiana simplex has been cultivated by our Chinese people in both ancient and modein times for medical use, and for the making of furnitures and musical instruments, as well as ornamental tree.2. The distribution of this plant is wide-spread almost through entire China. According to the writer's observation it grows vigorously and reaches its maximum height in the lower part of the Yangtze basin.3. In 1929 Yen states that sex differentiation of Firmiana simplex might be due to the fact of nutrition, the writer, after visiting various parts of China, discovered that everywhere this plant has the same phenomenon of sex differentiation. This fact leads to a new conclusion that sex differentiation in this plant is certainly not entirely influenced by nutrition; it may be due to the historical factor of the plant it-self.4. No phcllum is developed in the hypodermis except in the region of Icnticels. Epidermis, therefore, may grow permanently and never break off. These are very rare even among the perennial woody plants.5. Characteristics which are considered peculiar to Firmiana simplex are: (1) closely arranged epidermal cells may become loose during the increase of the diameter of the branches, (2) rupturing of the fissures on the bark while the branch grows, (3) development of secondary epidermis from the hypodermal cells within the fissures and the lenticels, and (4) continuous division of the epidermal cells. All these characteristics are facts which explain the permanence of epidermis.

1、梧桐具有观赏,药用,制造器物等价值,我国民众自古就加栽培利用。 2、梧桐上分布几遍及全国,据我所见到的是长江中、下游地区所生长的比较繁茂高大,北京的最为矮小,厦门比北京的高大些,昆明虽然不及长江流域的但比厦门的似乎又茂盛高大些。 3、关于梧桐花两性分异,以前以为是养料的关系,但是现在观察了各地的梧桐花,发现它们对于性的分异都是一样之后,我认为造成性的分异可能下仅是单纯养料的问题。也许和有机体自身的历史发展因素有关。 4、苹婆和大多数多年生木本植物相同,它们茎部表皮的寿命不过1年。新枝条的下皮层在当年夏秋之际分化木栓组织。以后,表皮细胞就会枯死脱落。 5、梧桐,除皮孔而外,枝干表皮层之下一概不发生木栓组织,表皮层与枝干同寿,这是多年生树木中少有的微状。 6、梧桐表皮细胞,随枝干之加粗而疏离,又可分裂增多,同时条状裂纹也可以随枝杆直经之增加而开裂加宽,这些都是表皮长生不老的因素。 7、梧桐树皮裂纹中的下皮细胞向外分裂成为次生表皮组织,这是很特别的。
