求翻译：本设计中是采取机械补偿式三组元连续变焦系统中镜头组关系进行设计的，通过变焦组和补偿组位移变化，得到其位移曲线图。为了降低设计难度，不需要计算其运动方程，而通过采点的方式得到其大致的运动关系，方便编写程序。是什么意思？

This design is the relationship between the design of the three groups to take mechanical compensation continuous zoom lens group zoom group and compensation group displacement, by their displacement curves. In order to reduce design complexity, do not need to calculate the equation of motion, rough

This design is to take mechanical compensated $3 group for zoom lens group in the system design of a relationship, with Zoom and compensation group shift changes, the graph shift. In order to reduce the design effort, it is not necessary to calculate the equation of motion, and the Picking point alo

In this design is adopts the machinery compensation type three component continual focal variation system medium shot photo group to relate carries on the design, through the focal variation group and the compensation group displacement change, obtains its displacement diagram of curves.In order to

Mechanical compensation is taken in the design of this three-component continuous zoom lens group in relation to the design of the system, by displacement and compensation group zoom group, get the displacement graph. In order to reduce the design difficulty, do not need to calculate the equation of
