non-dimensional parameter

Furthermore , a multi-parameter analysis showed that the Reynolds number is a key non-dimensional parameter to characterize the measurement accuracy of small scale flow meters .

此外，综合多参数的实验结果表明，雷诺数是判断小口径超声波热量表测量准确性的重要无量纲参数。

Under the condition of the steady pressure and good aeration , the criterion of flow stability was established through non-dimensional parameter Fr , which reflected the relationship between flow stability and gas velocity .

在给料罐压力相对稳定和通气良好的条件下，通过无量纲参数Fr建立粉煤流动稳定性判据，揭示管中气速与流动稳定性的关系。

But so far , the number of usable non-dimensional parameter is finite , particularly in the application of multiple concurrent faults diagnosis .

但是到目前为止，可供使用的无量纲指标数目有限，应用在多重并发故障诊断的无量纲指标更是少之又少。

In the first part of the paper , the non-dimensional tension parameter T0 / ρω 2R2 is found by an approximate dynamic analysis of the two-for-one twisting balloon .
