Tikz 节点文本格式问题

Question

该问题与以下内容相关：Tikz 节点中的文本不遵守基线跳跃。

以下 MWE 和输出演示了在节点中设置字体大小的 8 个用例。结果取决于传递给的键的选择\node、使用字体大小开关（例如\Large节点内部的），以及可能需要\par在需要应用字体大小和基线设置的文本块末尾添加。

沒有node font=密鑰傳遞給\node。
与 1 相同 +\par在第一个文本块的末尾添加。
与 2 相同 +\par在两个文本块的末尾添加。
使用钥匙node font=\Large，不\par。
与 4 相同但添加\par在两个文本块的末尾。
与 5 相同，但替换node font=\Large为font=\Large。
用语法替换字体大小开关\fontsize{}{}\selectfont{}，没有\par。
与 7 相同，但添加\par在两个文本块的末尾。

这些测试表明，当传递给的键中省略node font=和时，需要在第一个文本块的末尾添加（示例 2），但不需要添加到第二个文本块的末尾（示例 3）。在 OP 的帖子中，这解释了为什么示例 2 排版不正确。font=\node\par

添加node font=（示例 4-5）或font=（示例 6）需要添加\par（示例 5-6）。

\fontsize{font size}{baselineskip}\selectfont只要par添加，就可以使用语法（示例 7-8）更改字体大小和基线跳跃。

这是 8 个示例的输出：

这是 MWE：
