增加段落之间的间距，同时保持 itemize 环境中项目之间的间距

Question

我尝试使用该包来增加段落之间的间距parskip，但它也增加了我itemize环境中项目之间的间距。

如何在不改变项目之间间距的情况下改变段落之间的间距？

梅威瑟：

\documentclass[12pt]{article}
\usepackage[utf8]{inputenc}
\usepackage{amsmath, amsthm, amssymb, mathtools}
\usepackage[skip=1.5\baselineskip, indent=0pt]{parskip}


\begin{document}
Hermitian operators have the following properties:
\begin{itemize}
    \item The eigenvalues are real
    \item The eigenfunctions are orthogonal
    \item The eigenfunctions of any Hermitian operator is complete, meaning that any function can be represented by a linear combination of the eigenstates.
\end{itemize}

But this means that we have no idea what the momentum is. Hence, classically speaking, we cannot say exactly where the particle would be at a later time because we don’t know where it is heading and how fast. 

If the elapsed time is not so long, then the particle will be reasonably expected to be found near the starting point. But other than that, we cannot say where the particle is exactly located at any later time.
