The basic designing principle of a differentialaction microscopic displacement with flexure hinges is described.
阐述了差式微位移放大机构的基本设计原理，分析了机构中位移损失的原因。

The difference of the lengths of the two chains produces a differentialaction to damp the reverse inertia impact of the counterbalance weight.
两组链条长度之差产生差动功能，可缓冲平衡重的换向惯性冲击。

As we all knew, the differentialaction of the complete differential PID controller had nearly no effect as which last only one period, so that the advance control of error can't be achieved.
