Because when the frequency of close to the meshing of gears susceptible to the naturalresonancefrequency.
因为当啮合频率接近于齿轮系的固有频率时容易发生共振。

Flaky morphology of magnetic alloy particle material can raise its naturalresonancefrequency because of strong shape anisotropy, which is advantageous to acquiring high microwave permeability.
