根据支撑架的冲压工艺性，进行了排样设计与模具结构设计，以及切舌定距方式的应用。

According to the punching technology character of brackets, layout design and die structural design are carried out, as well as stamping and bending fixed distance fashion is applied.

因此，进行应变测量时，应用常规的杠杆引伸仪，受到安装方式和测量标距等条件的限制，往往只能测量轴向一定范围内的平均应变。

So, in the process of strain-measuring, when we apply the normal lever extension meter, it is confined by conditions, such as the install pattern, measurement standard and so on.
