This method of the transportation along a cable is found by laborers of our nation when transport soil during their participating in hydraulic engineering constructions of large type. The method is to rack up two cables along the slope of a hill parallel each other, Between the cables a fixed pulley is hanged. A string surround the pulley. Two boxes C and D, prepared for containing the soil, is tied up at each end of the string When the box, say C, full of soil, slides down along the cable from above by gravity, the vacant box D must then ascend up along the other cable simultaneously. Doing thus again and again, the soil is then transported to the bottom of the hill quickly. The distribution of tensions in the perfectly flexible cable, to be encircled tightly on the rough column, has been stated in some texts of mechanics. In this article, considering the mass of the string and the boxes, and the friction between the string and the pulley, and under the condition of inextensibility of the string, we have established a closing system of the non-linear ordinary differential equations which determines the motion of the boxes, and established also the formula for the distribution of tensions in the string in the state of motion.

高线运輸为我国劳动人民在大型水利工程建設过程中所发明的运土的法子,其法为在一傾斜的山坡上架起平行二高线,二高綫中間裝一定滑輪,定滑輸上套上一繩子,繩子兩端系上甲乙二盛土箱,由于重力的作用,当盛滿土的箱子甲沿高綫滑下时,空箱乙必沿另一高綫上升,如此周而复始,虛土即迅速运至山下。紧張地纏在一粗糙柱上的不可伸長的柔繩中的張力分布問題在許多力学教程中多有記載。本文顧及繩子及盛土箱的質量、繩子与滑輪間的摩擦力并假定繩子不可伸長的条件下,建立了决定盛土箱运动的封閉性非綫性常微分方程組,以及在运动狀态下繩子中張力分布的公式。

In this paper an attempt was made to analyze the influence of deep foundation fault. seams and various elasticity on the stresses of gravity dam by the approximate method of the theory of elaeticity. In the following cases a series of mathematical results have also been obtained. 1. The fault seam is located in the centre of the bottom of dam, concrete of dam and rock of foundation possess various elasticity. 2. The fault seam is located in the centre of the bottom of dam, the rock at the left and right sides of fault seam possess vavious elasticity. 3. Fault seam have various locations corresponding to the axis of dam. At the same time photoelastic study is applied to verify the calculated results. The theoritical calculated results agree with the experimental results.

The characteristics of flow in cooling reservoirs, due to the presence of thermal stratification and the heat exchange on the surface, is far more complicated than that of flow usually encountered in hydraulic engineering. The criteria for similarity of flow in models and prototypes are so numerous that the satisfication of all of them is not practical. The author presented, in 1959, the criteria for similarity with due consideration of the fact that on one hand, they should be sufficient for the reproduction of main hydraulic and thermal characteristics in models; and on the other hand, it should be practical to satisfy the criteria in ordinary hydraulic laboratories. The similarity laws thus obtained are presented in equation (17). When the room temperature and moisture content can be controlled and adjusted the similarity laws as shown in eq. (13) are recommended. A series of verification tests and field observations were carried out in the following years, the latter being made in two cooling reservoirs. In one of the reservoirs, which has an average water depth of 4.5m and a surface area of 5 km~2, general flow pattern of the surface layer and of the bottom layer of the thermal density current was observed. They were well verified in a model with length scale L_r=250 and depth scale Z_r=40. The other cooling reservoir is a much smaller one, with surface area of only 9000 m~2 and an average water depth of 2.5m. Besides flow characteristics, the variation of the temperature field of the reservoir and of the total heat balance with respect to time were carefully measured. A model with L_r=15 and Z_r=6 served to verify the hydraulic and thermodynamic data obtained in the field. The paper is a collective report, including the derivation of the similarity law and its verifications, and a discussion of the scale effects.

冷却池中的水流运动,由于存在着水流本身的溫差作用及池面的散热受热作用,其运动規律,要較一般水流运动規律复杂得多;其模型相似条件,亦极难全面滿足,本文从整个水池的基本相似要求出发,着重考虑了水面溫度場相似的要求,提出了模型律;对存在着的比尺矛盾作了一些探討,并在室內和現場作了一些試驗驗証。几年来的試驗实践說明,虽然目前的模型相似問題,还有不少环节沒有解决,直接用热水作为試驗介貭的模型試驗,不失为規划冷却池工程布置和估計水面散热能力的一种有效工具。
