光功率比计算

说明：  通过输入三基色波长确定麦克斯韦颜色三角形，取颜色三角形中任一点，有这一点坐标求这三个波长光源对应的光功率比。 已写为gui格式，傻瓜式操作。
(The Maxwell color triangle is determined by inputting the three primary color wavelengths, and any point in the color triangle is taken. With this coordinate, the light power ratio corresponding to the three wavelength light sources is calculated. Written as GUI format, fool operation.)
