在页面顶部的 Memoir 类中保留 \section 标题前的空间

我正在使用 xelatex 和 Memoir 类。默认情况下，节标题前的空白垂直空间不会显示在 之后pagebreak。如果我想让它显示，我该如何修改它，即使它位于新页面的顶部？我可以看到其中memoir.cls有一个名为的长度\beforesecskip和一个\setbeforesecskip命令，但我不知道如何实现所需的效果。任何帮助都值得感激。

\documentclass[11pt]{memoir}
\usepackage{showframe}
%%% Book Layout %%%
\setstocksize{7.5in}{5in}
\settrimmedsize{7.5in}{5in}{*}
\setlength{\trimtop}{0pt}
\setlength{\trimedge}{\stockwidth}
\addtolength{\trimedge}{-\paperwidth}
\settypeblocksize{6in}{4in}{*}
\setulmargins{0.5in}{*}{*}
\setlrmargins{0.5in}{*}{*}
\setmarginnotes{0pt}{0pt}{0pt}

如您所见。第 1 和第 4 部分之前没有垂直跳跃，因为它们位于页面顶部。

有一种可能性是，重新定义 memoir.cls 中定义的一些内部宏（我认为这种行为仅适​​用于部分）：

\documentclass[11pt]{memoir}
\usepackage{showframe}

\setstocksize{7.5in}{5in}

\settypeblocksize{6in}{4in}{*}
\setulmargins{0.5in}{*}{*}
\setlrmargins{0.5in}{*}{*}
\setmarginnotes{0pt}{0pt}{0pt}
