The generalized force and generalized inertia coefficient may also be calculated by finite difference method, and so the actual motion of mechanisms subjected to known active forces may be analyzed.

用有限差分法还可求出机构的等效力（矩）和等效质量（转动惯量），从而可求解机构在已知外力作用下的真实运动。

Methods: Using alkalescence dyestuff as active substance, chlorobenzene as solvent and PVC as inertia backstop.

方法：以碱性染料苦酮酸盐为电活性物质，氯苯作溶剂，PVC为隋性支持体。
