“probability density evolution method”的概念、定义、翻译、参考文献-科学参考

单词	probability density evolution method
释义	probability density evolution method Encyclopedia 工学非线性随机振动释 probability density evolution method概率密度演化方法广义上，刘维尔方程、Dostupov-Pugachev方程、福克-普朗克-柯尔莫哥洛夫方程和广义概率密度演化方程等均以获取工程系统响应的概率密度为目标，因而可以统称为概率密度演化方法。狭义上，主要指以广义概率密度演化方程为核心的理论体系。这里按狭义理解。
