The intension of reduce rank is that the time constant of current-ring is regulated to the best of minimum, and low frequency signal is equated to common proportionalcomponent.
其降阶指把电流环时间常数调整到尽量小，低频信号段可等效为普通比例环节。

If the difference is large, then the manager knows his team feels this component has proportional risk.
如果差异很大，那么项目经理就知道其团队感觉该组件有成比例的风险。

It is well known that quantification has always been an essential component of classical design: proportional systems in particular have been keenly investigated.
