Basic quantities in stellar photographic photometry (in particular, colour index and "effective wavelength") are formulated according to the assumptions that: 1) stellar radiation may be represented by some black body equivalent and 2) within the limits of a single photometric "receiver", intensity-wavelength relationship of the radiation may be taken as linear.

Basic quantities in stellar photographic photometry (in particular, colour index and "effective wavelength") are formulated according to the assumptions that: 1) stellar radiation may be represented by some black body equivalent and 2) within the limits of a single photometric "receiver", intensity-wavelength relationship of the radiation may be taken as linear. Foundations and applicability of these assumptions are examined. On the basis of this the photometric side of the problems of space reddening etc. are discussed. We considered in detail the use of effective wavelength by objective grating method in stellar photometry and have shown that with suitable photometric technique and right choice of grating it is possible to obtain in two colour photometry (say, ultraviolet and photovisual) the results with same degree of accuracy as might be obtained in three colour arrangement.

本文對着當前的發展,綜述了照相方法在恆星光度学中的地位.接着用兩個簡單的假设,即星体幅射的黑體近似和累積亮度範圍中的直线近似,把恆星光度学中的基本定義(如有效波長、等光波長和色指数等)和主要问题(如空間红化,亮度效应等)表以公式.在进行的時候,我们详细地讨论了這兩个假设的依據. 我們提出了在兩色光度学中物端光栅所能接觸到的问题,着重地敘述了空间吸收和光度型的辨認,並且把应用这种方法的先決條件,它的優點和它所受到的限制加以讨论.

The so-called "landscape horizon" in this paper is viewed from the fact that the landscape acts as an objective and independent substance of matters on the surface of the earth Along a given line in any unit of regions the landscape may be sectioned crossly Landscape is a component part on the land of the landscape sphere, which envelopes the earth, so that its basic components are also .solid, gas, liquid, and organic matters. The science of the landscape may be therefore considered as regional geography. All the evidences concerning the completion of major types of the landscape, the floral and faunal extinction and new species—production, and especially the apperance of man prove thai the history of the landscape can only date back to the begining of the Quaternary Era, so that palaeogeography may be restricted in this scope. According to time, the landscape includes naturally the weathering crust as its bass, and its upper end should be coincided with the top of air near the ground, or of the highest trees. Thus its thickness is all the same in standard to any reginal unit Obviously, the extent of the landscape do not exceed the continental slopes in the sea. Judging from the statements mentioned above, a horizon of four dimensions has to logically occur in any unit of regions. It is the "landscape horizon", in which vertical and horizontal differentiations have continuously proceeded. Controlled by some geographic processes, the "landscape horizon" has been vertically differentiated into three sub—horizons: the sub—horizon of weathering crust, of soils, and of biotic community and air, They altogether revealed the morphological structure in types of the landscape. The horizontal differentiations conditioned by some other gcogra phic processes indicate the relationships of the landscape in areal continuity. The diagrams of the "landscape horizon" must be based on field works. Here are two examples, one, for the "landscape horizon" of steppe, and the other, of desert (figures 1 and 2). These diagrams can be used to (1) point out the structural and ecological features, in other words, the typological characteristics of the landscape, (2) determine the boundaries of regions and provide a basis for the plan of agriculture, and (3) help to study some theoritical problems of regional divisions. The author believes that the concept of the "landscape horizon" may be nseful in practical as well as in theoritical works.

本文所谓“景观层”是出之于景观是地球表面上起作用的一种客观的独立的物质实体的看法。在区域任一单元的一定线上景观能用剖面体现出来。景观是环围地球的景观壳在陆地上的一个组成部分,因之它的基本组成要素也是固体,气体、液体、和有机质。以此之故景观学可以认为是区域地理学。所有景观主要类型之完成,动植物之死亡和新种之产生,和特別是人类之出现的证据都证明景观历史仅能回溯至第四纪之始。古地理学因此应当限于这个范畴之內。根据时间,景观的下限自然包有风化壳,而其上限则与近地面空气层或最高乔木顶部相一致。显然,它的广度不超过大陆斜坡。由上可知一种具有四度空间的层必见于任何区域单元之內。这就是“景观层”。其中垂直和水平分异作用不断进行着。为一些地理过程所规定,“景观层”在垂直方向上被分异为风化壳,土壤、和生物与空气三个亚层。它们共同揭示了景观类型的形态构造。而受制于另一些地理过程的水平分异则表明景观在空间连续性上的相互关系。“景观层”图解根据野外工作制出。这里举出二例:一为草原“景观层”图解,另一则属于荒漠(图1和2)。这种图解可用以(1)指出景观的构造和生态特征,换言之,郎其类型特点;(2)确定区域的界限并为农业规划提供基础,和(...

本文所谓“景观层”是出之于景观是地球表面上起作用的一种客观的独立的物质实体的看法。在区域任一单元的一定线上景观能用剖面体现出来。景观是环围地球的景观壳在陆地上的一个组成部分,因之它的基本组成要素也是固体,气体、液体、和有机质。以此之故景观学可以认为是区域地理学。所有景观主要类型之完成,动植物之死亡和新种之产生,和特別是人类之出现的证据都证明景观历史仅能回溯至第四纪之始。古地理学因此应当限于这个范畴之內。根据时间,景观的下限自然包有风化壳,而其上限则与近地面空气层或最高乔木顶部相一致。显然,它的广度不超过大陆斜坡。由上可知一种具有四度空间的层必见于任何区域单元之內。这就是“景观层”。其中垂直和水平分异作用不断进行着。为一些地理过程所规定,“景观层”在垂直方向上被分异为风化壳,土壤、和生物与空气三个亚层。它们共同揭示了景观类型的形态构造。而受制于另一些地理过程的水平分异则表明景观在空间连续性上的相互关系。“景观层”图解根据野外工作制出。这里举出二例:一为草原“景观层”图解,另一则属于荒漠(图1和2)。这种图解可用以(1)指出景观的构造和生态特征,换言之,郎其类型特点;(2)确定区域的界限并为农业规划提供基础,和(3)有助于探讨区划的某些理论问題。因之,“景观层”概念在实践和理论工作上是有用的。

Corn,kao-liang,soy bean and millet are the four main crops in Shenyang district.The objectives of this study are: (1)to determine the mechanized farming process of these four crops; (2)to select the more adaptable tractor models and farm machineries in order to complete the required processes; (3)to estimate the man labor required for each process during the whole growing season of these crops; (4)to estimate the cost of operation of the mechanized farming processes of these crops per unit area as compared with the customary farming methods. This study was carried out on the college farm of Shenyang Agricultural College. Each crop occupied an area of arround six hectares.The soil to be tested is a forest brown clay loam. From this study,we determined the mechanized processes in culturing each crop. Due to our customary intensive farming system,some mechanized processes are assisted with man labors and hand tools.Most of the adaptable tractors and farm machineries to be selected are manufactured by our own country.The two years yields of these four crops were all higher than the average amount of this district.The amount of man labor required for each farming process of different crops was deter- mined.The unit costs of operation of these four crops are lesser than the operation costs of customary farming methods. Therefore,the suggested mechanized farming processes of these four crops as discussed in this paper are better than the customary farming processes in agronomy requirements including yields,unit cost of operations and easiness of farming operators.

试验证明,无论从产量、农业技术要求、成本、减轻劳动程度及各时期用工量等因素来看,在沈阳地区对高粱、玉米、大豆和谷子四大作物实行机械化是完全可能的,而且是有利的。在拖拉机及农机具的选型上要求并不严格,国产拖拉机及农机具均可满足作业质量要求。本文对四大作物的各项作业田间工艺程序进行分析讨论,并提出尚待选、改、创的机具项目。
