一个很实用的Delphi信息管理系统界面源码，这个界面集成了菜单、框架、按钮以及图文导航等众多效果，是一个开发基于Delphi的信息系统时，可借鉴引用的一个用户界面，对于不擅长界面设计的Delphi编程者，这个可以解决你的燃眉之急，哈哈 。

说明：  模式传输的光束质量，模式经过增益饱和放大的光束质量因子的模拟主要运用的方法是最小二乘法拟合。其思路是用分步傅里叶法得到多个不同位置的光强分布，然后通过二阶矩方法得到束半宽，用最小二乘法拟合得到传输半径的一元二次方程，形式如下(The simulation of beam quality factor of mode transmission and mode gain saturation amplification is mainly based on least squares fitting. The idea is to obtain the intensity distribution at different positions by step Fourier method, and then get the beam half-width by second-order moment method. The quadratic equation of transmission radius is fitted by least square method in the form of the following.)
