对拉伸试验过程中主要试验速率控制方法的相关参数，如位移速率、应变速率、应力速率等在试验过程中不同变形阶段对应关系的变化进行了分析，并对相应换算方法进行了整理和研究，还使用实际试验数据对不同变形阶段的相关对应关系加以验证。结果表明：在试验前，要了解试样材料相关应力-应变（或载荷-时间）等相关曲线的变化规律和特征，且应根据具体的试验条件、要求和目的，选择相应的试验控制方法。

The change of corresponding relations of correlation parameters in different deformation stages during the process of test were analyzed, the correlation parameters are the main test rate control method during the tensile test, such as displacement rate, strain rate and stress rate. The corresponding conversion methods were collated and studied, and the corresponding relations in different deformation stages were verified by using actual test data. The results show that the change rules and characteristics of stress-strain (or load-time) curves and other related curves of specimen materials should be understood before testing, and the corresponding test control method should be selected according to the specific test conditions, requirements and purposes.
