缩尺比
scale ratio
- 同时也发现，由于缩尺效应问题的影响，现有减压试验方法和理论已不适应小比尺掺气水流的减蚀问题研究。
In the meantime, the present theory and method are not applicable for the study of small scale spillway depression model on account of scale effect. - 但深海平台的模型试验需要很大的水池，目前世界上还没有一个水池用常规的缩尺比能够进行该项试验。
However, model tests for deep sea platforms require very large model basins and no existing model basin in the world can carry out such tests with traditional scale ratios. - 对于超大跨度钢管混凝土拱桥，由于受模型缩尺比所限，通常在气弹模型试验中不能单独模拟出拱肋中单根钢管的刚度，目前常采用集中刚度法用一个芯棒模拟整个钢管桁架的刚度。
In the design of aeroelastic model of long-span concrete-filled steel tube arch bridge, the method of using an equivalent mandril to simulate the stiffness of whole arch rib is mainly used at present.
