我正在使用大学模板，根据我的审阅者的说法，我的段落行距不是 1.5。因此，在尝试更改时，我在 cls 文件中发现了这一点。
\def\setstretch#1{\renewcommand{\baselinestretch}{#1}}
由于我是乳胶新手，所以我不知道它的作用，但上面的评论警告不要更改它，因为它可能会影响脚注、标题、标题等。我不知道#1 从哪里来，对我来说看起来像一个参数。
有人告诉我在每一章中添加行距以避免表格、边距等出现任何问题。这里是类部分，我认为它定义了所有间距等。我还发现了一个用于 setspace 的单独文件。

%
% LaTeX Document style option "doublespace"
% -- usage: \documentstyle[...,doublespace,...]{...}
%
% This style option produces a double-spaced document by redefining
% the LaTeX parameter \baselinestretch to 2.
%
% It also fixes a number of problems with standard LaTeX, as follows:
%
% 1. A new environment "singlespace" is provided, within which single
% spacing will apply.
% JFL - changed so that it works in regular text and so that vertical
% space is before and after is correctly computed
% 2. Double spacing is turned off within footnotes and floats (figures
% and tables).
% 3. Proper double spacing happens below tabular environments and in other
% places where LaTeX uses a strut.
% 4. Slightly more space is inserted before footnotes.
% 5. JFL - fixes spacing before and after displayed math
%
% Note: This version sets a baselinestretch of 2. If this is too much,
% put \setstretch{1.7} (or some appropriate value) before the
% \begin{document} command. To print the document with single spacing
% again, without removing "singlespace" environments, just put a
% \setstretch{1} at the top of the document.
%
% PLEASE REPORT ANY BUGS
%
%
% Known bugs:
% . It might be nice if spacing before the footnote rule (\footins)
% were provided in a tidier way.
% . Increasing struts may possibly cause some other obscure part of
% formatting to fall over.
% . \begin{singlespace}\begin{quote} produces the wrong spacing before
% the quote (extra glue is inserted).
% . shouldn't @setsize stretch parskip as well?

%% FILE: setspace.sty in SYS2.TEX.PUB.ISULATEX.STYLES
%% AUTHOR: Erica M. S. Harris
%% DATE: April 1990
%% MOD: March 1991
%%%
%%% Update to LaTeX (2e) : 6 Feb 1996.
%%% Description: LaTeX Document Package "setspace"
%%%
%%% Usage:
%%% \documentclass[...]{...}
%%% \usepackage{setspace}
%%%
%% Based on the doublespace option created by Stephen Page.
%%
%% This style option provides commands and environments for doing
%% double and one-and-a-half spacing based on pt size.
%%
%% Single spacing is the default.
%%
%% Three commands, \singlespacing, \onehalfspacing, and
%% \doublespacing, are for use in the preamble to set the overall
%% spacing for the document. If a different spacing is required then
%% the \setstretch{baselinestretch} command can be used in the
%% preamble to set the baselinestretch appropriately. The default
%% spacing with this style option is single spacing.
%%
%% Three environments, singlespace, onehalfspace, and doublespace,
%% allow the spacing to be changed within the document. Both the
%% onehalfspace and doublespace environments are intended to increase
%% the spacing, so the onehalfspace environment should not be used in
%% a double spaced document. If an increased spacing different from
%% one-and-a-half or double spacing is required then the spacing
%% environment can be used. The spacing environment takes one
%% argument which is the larger baselinestretch to use,
%% e.g., \begin{spacing}{2.5}.
%%
%% \footins is adjusted the same as \parskip - appears to work. Lose
%% stretch parts but don't consider that to be crucial
%%
%% Removed code for altering spacing before and after displayed
%% equations - just looked too much.
%%
%% MODS:
%% Redefinition of \spacing and \endspacing for consistency with
%% TeX 3.x inserted by George Greenwade. Modification provided by
%% Philip Ross ([email protected]) and John Byrne via INFO-TeX.
%%
%% PLEASE REPORT ANY BUGS
%%
%% Old Documentation follows:
%% 1. A new environment "singlespace" is provided, within which single
%% spacing will apply.
%% JFL - changed so that it works in regular text and so that
%% vertical space before and after is correctly computed
%% 2. Double spacing is turned off within footnotes and floats (figures
%% and tables).
%% 3. Proper double spacing happens below tabular environments and in
%% other places where LaTeX uses a strut.
%% 4. Slightly more space is inserted before footnotes.
%% 5. JFL - fixes spacing before and after displayed math

%% POSSIBLE BUGS:
%% . Increasing struts may possibly cause some other obscure part of
%% formatting to fall over.
%% . \begin{singlespace}\begin{quote} produces the wrong spacing before
%% the quote (extra glue is inserted).
