这基本上是一个后续问题自定义标题中的一致行距。
在我看来，这\strut只能在采用一行或两行（在输出中）参数的宏中起作用，所以我对更普遍的问题感兴趣。是什么机制导致线条根据其下行和上行调整其基线位置？是否可以操纵此机制以至少使文本和标题与网格对齐？我理解数学，表格和数字是一个新的复杂程度，所以现在让我们专注于文本。字体和字体大小有影响吗？
标题可能是一个不好的例子，因为它们最多只有一两行，但同样的一般问题也适用于其他环境，如引号。
在以下根据原始问题改编的例子中，重音符号会占用很多行空间，而另一方面，如果只使用小写（或小型大写）字母，我们就会失去一些空间。

答案1
主要问题是文本大于指定的基线跳跃，因此\lineskip使用的间距永远不会提供均匀的间距，请参阅第 1 页上的日志。
如果想要均匀间距，正常的做法是增加基线跳跃，如第 2 页所示。
如果您希望段落内的间距均匀，但小写文本的间距更近（有点不寻常但......）那么您可以先在水平框中设置文本，然后测量其高度加上深度，然后设置\baselineskip为比这更大，如在第 3 页上一样。
