用Ritz-Galerkin方法解边值问题： u +u=-x,0<x<1, u(0)=u(1)=0,精确解为u*(x)=sinx/sin1-x； 得出结果与精确解作比较，画出误差分析图(With the Ritz-Galerkin method to solve the boundary value problem: u' ' + u =- x, 0 <x<1, u(0)=u(1)=0,精确解为u*(x)=sinx/sin1-x； 得出结果与精确解作比较，画出误差分析图)

这是一个气体检测的程序，用于检测甲烷等气体，很有用的啊(This is a gas detection program for detecting methane and other gases, useful.)

该程序可以用作计算谐振器的传输特性，包括透过率、相移、色散、延迟等。(describe resonator)
