时曲线 meaning in Chinese

drug-time curve
duration curve
duration hydrograph

For this reason the cycloid is called the tautochrone .
由于这个缘故，摆线又叫做等时曲线。
Based on the feature of subgrade construction and with the analysis of the observed settlement data , a series of stress - strain isochrones are arranged in this paper
本文基于高速公路路基填筑的特点，通过实测沉降资料的分析，整理出一系列应力应变等时曲线。
The study demonstrated that linear visco - elastic parameters of rheological models built by theoretical modeling methods were constant while nonlinear visco - elastic parameters were not constant and changed as stress level changed and that visco - plastic parameters determined the shape of stress - strain curve
研究表明：运用模型理论建立的流变模型的线性粘弹性参数在低应力水平下是惟一的，但非线性粘弹性参数不惟一，并随应力水平的变化而变化，而粘塑性参数的大小决定了应力应变等时曲线的形状。
