其中定位点到线路中心的距离m值就要通过理论计算才能得出,定位点位置变化直接影响m值变化,所以定位点与m值的关系也是本文论述之一

In order to obtain data corresponding to the wrist arm, we have to go through the actua measurement
For example, bounded, super high and pillar slope
The measurement data are relatively different from design values
So calculation of cantilevers is on the basis of the actual data
We know that the length of wrist arm is A=l* δ +Cx+m+C
When the positioning po
