中文说明：
平面光波从空气（折射率为1）入射到石英玻璃上（折射率为1.45），用MATLAB做出p、s分量的振幅反射率和振幅透射率以及他们的绝对值随入射角度的变化曲线。
English Description：
Plane light wave incident on quartz glass from air (refractive index is 1) is 1.45. Amplitude reflectivity and amplitude transmittance of P and s components as well as their absolute values with incident angle are obtained by MATLAB.
