electro motive meaning in English

电动的

Electro motive strain is a common method used to measure the maximum strain in stress concentration district , or mostly to extrapolate certain unknown value of stress utilizing some known value
应变电测法是测量应力集中区最大应变值的一种比较常用的方法，主要是利用某些可测点的值去推测不可测点的值，即通常所说的外推法。
But in fact , a problem lies in the process of using electro motive strain ; we find that , to the same question , precision of results predicted by gm ( 1 , 1 ) model differ widely when sampling positions are different
但在实际运用应变电测法时存在一个问题，对于同一问题，采样位置不同时，用gm ( 1 ， 1 )模型预测结果的精度会有不同。
According to the problem that sampling position has certain influence on precision of the gm ( 1 , 1 ) model , in this paper , we try to find out the best sampling position to solve maximum value of stress or strain when using electro motive strain and extr apolating method of gm ( 1 , 1 ) model , so as to offer a theoretical foundation for applying electro motive strain more reasonably
针对采样位置对模型精度有一定的影响这一问题，本文通过三个具体例子来研究采样位置对模型精度的影响，探求用应变电测法和gm ( 1 ， 1 )模型外推法求最大应力值时最佳的采样位置，从而为更合理的运用应变电测外推法提供一个理论依据。
