说明：  高斯混合模型就是用高斯概率密度函数（正态分布曲线）精确地量化事物，它是一个将事物分解为若干的基于高斯概率密度函数（正态分布曲线）形成的模型。
(Gaussian mixture model is to use the gaussian probability density function (gaussian distribution curve) accurately quantify things, it is a to break things down for several based on gaussian probability density function model (normal distribution curve).)
