This paper analyzes the probability density distribution of the non-soluble deposit density, and hence deduces a combined probability density distribution function.

笔者分析了灰密的概率密度分布，并推导出盐密与灰密的联合概率密度函数。

We can talk about the wave function squared, the probability density, or we can talk about the radial probability distribution.

我们可以讨论它,波函数的平方，概率密度，或者可以考虑它的径向概率分布。
