其中分为四针背筋（成形三根筋）、三针背筋（成形二根筋）、二针背筋（成形一根筋），转换背筋之分，只需更换不同的针板、压脚即可，操作很是方便。
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。
