计算光机耦合仿真中的光学镜面的变形情况，分离刚体位移，采用泽尼克多项式耦合。并有使用例子。(The deformation of the optical mirror in the opto mechanical coupling simulation is calculated. The displacement of rigid body is separated and the Zernike polynomials are coupled. And use examples.)

描述在matlab环境下，bch的误码率，仿真给出了在编码情况下的误码比较，可以清楚的得出bch码的编码增益。(Describes the matlab environment, bch the BER, the simulation is given in case of error in the code comparison can be drawn clearly bch code coding gain.)
