Divide into four stitch back muscle ( take shape three muscle ), three stitch back muscle ( take shape two muscle ), two stitch back muscle ( take shape a muscle ), changing the difference of back muscle, only need to change different needle boards, press foot, it is extr - emely convenient to operate
其中分為四針背筋（成形三根筋） 、三針背筋（成形二根筋） 、二針背筋（成形一根筋） ，轉換背筋之分，只需更換不同的針板、壓腳即可，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
針對采樣位置對模型精度有一定的影響這一問題，本文通過三個具體例子來研究采樣位置對模型精度的影響，探求用應變電測法和gm （ 1 ， 1 ）模型外推法求最大應力值時最佳的采樣位置，從而為更合理的運用應變電測外推法提供一個理論依據。
