我使用带有小字体大小的 beamer（因为否则文本会非常大）\begin{tiny} ... \end{tiny}。有时我会使用 double itemize（因此有两个级别）。这会产生以下两个意想不到的效果：
- 在内部 itemize 环境中，字体大小变为正常
- 在内部逐项列举环境中以及在内部逐项列举环境之前的最后一项中，行距发生了改变（可能变为正常大小文本中的行距）。
示例代码

\usetheme{Darmstadt}
\usepackage[utf8]{inputenc}
\usepackage[english]{babel}
\usetheme{Dresden}

已解决部分
第一个问题的解决方式是\begin{tiny} ... \end{tiny}在内部项目化环境中的文本周围放置另一个项目（纠正字体大小）并在内部项目化环境结束之前留一个空行（纠正内部项目化环境中的行距）。
\documentclass[11pt]{beamer}

这是可行的，但显然不是预期的方式，而且是一种肮脏的黑客行为。
未解决部分
我找不到任何方法来解决第二个问题（内部项目环境之前的最后一项中的行距）。
解决方案思路
\renewcommand{\baselinestretch}{.55}在相关项目的开头。这给出了看起来正确的项目间距。但它非常不通用，.55 是通过反复试验得出的，我担心每当我更改某些内容时，这可能会崩溃。- 设置较小的文档默认字体大小
\documentclass[8pt]{beamer}。8pt 是可以接受的最小字体大小，但仍然很大。
解决这个问题的通用方法是什么？我确信我不是第一个遇到这个问题的人。
答案1
我建议使用 beamers 自己的字体机制：
\documentclass[11pt]{beamer}
\usetheme{Darmstadt}
\usepackage[utf8]{inputenc}
\usepackage[english]{babel}
\usetheme{Dresden}
\begin{document}
