合成特征 meaning in Chinese

composite character

After the discussion of the switch reference , the characteristic and regularity of the switch and merge by dual grating scales , this paper designs the hardware circuit to execute the method of dual grating scales ’ dual measuring , count values switch and merge , designs different circuit module of the dual grating scales ’ s signal process based on fpga , such as the quadruple module , the speed identify module , the switch module , the merge process module
经过对双光栅计数切换基准、切换与合成特征和规律的探讨,本文设计了实现双光栅尺双重测量、计数值切换合成法的硬件电路,主要通过可编程芯片fpga ,设计了双光栅尺信号处理的各电路模块,如双光栅尺信号四倍频辨向模块、速度判断模块、切换模块、计数值合成处理模块。
