The characteristics of the stratified flow in the recirculating water for thermal power plants, due to the presence of density current, are far different from those of ordinary non-stratified flow.Thus, the principles of planning and designing any thermal hydraulic structures as well as the research program for it, ought to reflect proper consideration of the existence of flow stratification. This paper, succeeding the preceding one "The Law of Similarity of Flow in Cooling Reservoirs", is a resume of the research works done at the Institute of Hydrotechnical Research, Peking, for some twenty hydraulic projects of cooling reservoirs.It includes the following three main topics: (1) method of modulating thermal condition of water surface and method of assessing its cooling capacity, (2) flow characteristics of thermal density current in cooling systems, and (3) some general rules on the hydraulic design of outlets and intakes in reservoirs or rivers used for cooling purpose.

2K slip-line-field solution of metal forming problem is mostly an approxi-mate one because of the complexity of the boundary condition. It is desirablethat the solution be verified experimentally in order to judge completelyits applicability. It is explained in this paper what the velocity component contours in slip-line-field are and how to draw them. Experimentally, the contours of the dis-placement increment component can be ascertained by using Moire method. Bycomparing theoretical contour patterns with experimental ones, the slip-line-field solution can be examined. The fact that the plastic plane flow of a disk is subjected to radial com-pression is studied and employed to show the approach of verification. Theresult shows that the centered-fan-field extending into the center of the diskin this case is suitable for smaller height to width ratios (h/w ≤3. 64). Animproved solution for larger ratios (h/w ≥5. 43) is proposed in accorclance withcorresponding Moire fringe patterns.

金属塑性成形问题因边界条件复杂通常只能求得近似的滑移线场解。为判定适用条件或作出修正,对这种解要进行实验检验。本文论述了滑移线场中理论速度分量等值线的概念及作法。云纹法可测出模型或实物在成形过程中的位移增量(速度)分量等值线。将理论与实验的等值线图作比较,可从速度场方面检验滑移线场解。结合圆盘承受径向压缩平面流动问题阐明了检验过程。结果表明,延伸至圆盘中心的有心扇形场适用于较小的高宽比(h/w≤3.64)。根据云纹图,对h/w≥5.43的情况提出了改进的滑移线场解。
