此类问题能被形式化为带有预放置模块的布局问题，关于此问题的求解方法多为随机优化方法。
These situations are formulated as the module placement with pre-placed modules. For solving the problem, the methods used are usually stochastic optimization placement algorithm.
谐波误差产生的主要原因是系统相对振动、几何布局失稳、随机干扰和机床进给能力不足。
The main cause to create harmonic error are the relative vibration in system, in stability of geometry configuration, random disturbance and in sufficient feeding ability of the machine tool.
