中文摘要:
      本文通过同一工程的正态和变态两种模型的对比分析,认为试验平原地区宽浅式河道平面上水力和热力特性或工程布置方案,变态模型可以满足相似要求。但是对研究地形条件复杂的河段或只研究河段局部地区及建筑物的水力热力特性,建议采用正态模型。
英文摘要:
      In this paper the actual experimental data are studied and analyzed simila- rity comparisons between undistorted and distorted river models. It is important to look into the similarity of the distorted model to the prototype. From analysing the experimental results, it is clear that the distortion should be applied only to those flows which possess. sufficiently wide cross-sections to contain the central regions, where the flow can be regarded as undistinguishable from the two dimensional flows.
