A homogeneous isotropic thin plate, on which the surface force ACTS and there are many actuators of discrete distribution, is considered.
考虑一均匀各向同性薄板结构，在板面内受面力作用，且在板的上下表面离散分布着压电执行元件。

An uniform distribution, isotropic thin plate, on which both surface there are discrete distribution piezoelectric actuators, is considered.
考虑一均匀各向同性薄板结构，在其上下表面离散分布着压电执行元件。

Two kinds of magnetic field distribution are discussed and the result show magnetizing current on interface can be replaced with discrete mirror image current for uniform, linear and isotropic medium.
