输出：

解决方案...尝试尽可能使用自动距离，这样您就可以通过对基本距离进行两三次更改来解决这些问题......

经过OP编辑：使用与tikzpicture相同代码的Beamer运行良好！

输出：

我只是没用过，siunitx但我想这不会有什么区别

Answer 2

我犯了一个粗心的错误。基本上在投影仪中，tikzpicture 有这个选项

\begin{tikzpicture}[very thick]

独立使用时，它具有以下功能

\begin{tikzpicture}[node distance=.2cm,label distance=2mm,very thick]

在投影机中，tikzpicture 应该具有与独立模式下产生正确输出相同的选项。
