回忆录：检查并修复单倍/一半间距所需的布局

Question

我正在使用memoir文档类，我花了一个小时来调试一个神秘的标题页间距问题：我的标题页有时包含在一个页面中，有时末尾被推到新页面中......我意识到如果我放：

\OnehalfSpacing

然后左对齐并不总是具有与我完全相同的间距：

\OnehalfSpacing
\checkandfixthelayout

有/无（我加了一条红线作为参考）：

请注意，该错误并不总是可见的，这里我需要混合 A 和 Q 字母才能使其可见......这里的间距很小，但在我的标题模板（使用SingleSpace/ flushleft/ adjustwidth...）中，差异更大，可以移动整个段落。

我不明白的是，文档中没有提到有关\checkandfixthelayout何时使用行距命令的任何内容。是他们只是忘记了，还是我遗漏了更微妙的东西？我获得的间距是否\checkandfixthelayout正确？

梅威瑟：

\documentclass[a4paper,10pt,leqno,openbib]{memoir}

\checkandfixthelayout{} % I put this one for safety, to ensure that the previous layout is fixed
\OnehalfSpacing{}
%\checkandfixthelayout{} % Try uncommenting the line to see the spacing difference

\usepackage{float}
