The optimal design of gear parameters in the movements of clocks and watches is a combinatorial optimization problem, which is too difficult to be solved optimally using traditional optimization methods.
在钟表机芯设计中，齿轮参数的优化设计是一个组合优化问题，很难用传统优化方法解决。
A miniature horological machine tool is designed.
设计了一台小型钟表机床,通过采用“嵌入式”三维精密工作台和铰链机构、齿形同步带、变频调速器等装置,使得机床整体结构紧凑、尺寸小,而且便于协调控制。
