带有长标题的章节标题

带有长标题的章节标题

我正在尝试使用 latex 撰写论文，并且修改了要使用的模板，但部分章节标题出现了问题。具体来说，由于章节标题是两端对齐的，而不是左对齐，导致单词之间的间距很奇怪。

我正在使用 titlesec 包并尝试过：

\titleformat{\section}{\raggedright\large\sffamily\bf}{\thesection}{1em}{}

我还尝试通过添加强制 titlesec 使一切变得正确

\usepackage[raggedright]{titlesec}

到我的序言，但似乎没有任何效果，标题文本仍然间距奇怪。我想可能是我的设置中的其他内容占了上风？

长标题图片

答案1

您已在加载包sectsty。然后使用

\sectionfont{\raggedright\large\sffamily\bfseries}

或者不是加载包 secsty 也\titleformat可以正常工作。如果您想允许连字符，请使用：

\usepackage{ragged2e}
\sectionfont{\RaggedRight\large\sffamily\bfseries}

答案2

该\pretolerance值太大，阻止了连字符和随之而来的换行，因此将行拉长到下一个可能的位置换行，即toobig... 在关闭它之后问题消失（通过评论它）

% This section is relevant to formatting within chapters
\linespread{1.8} %1.5 line spacing
\renewcommand{\rmdefault}{ptm} % sets roman font to Times ('ptm')
\renewcommand{\sfdefault}{phv} % sets serif font to Helvetica 
\renewcommand{\ttdefault}{lmtt} % sets text type font to Latin Modern Typewriter ('ptm')
\pagestyle{fancyplain} % retains control of headers and footers
\fancyhf{}
\fancyheadoffset{0.0in} % margin size at header
\renewcommand{\headrulewidth}{0.4pt} % thickness of rule in header line (0pt will make it disappear)
\lhead{\fancyplain{}{}}
\rhead{\fancyplain{\leftmark}{\leftmark}} %prints current chapter name in the right header
\fancyfoot[R]{\thepage}
\chead{\fancyplain{}{}}
\renewcommand{\footrulewidth}{0.4pt} % thickness of rule in footer line

\headsep=12pt % Sets distance between header rule and text
\parindent=12pt % Sets indentation for each paragraph
\parskip=0.1in % Sets vertical space before a new paragraph
\widowpenalty=500 % elliminates widows (single lines of a paragraph on the top of the next page), see line below
\clubpenalty=500 % these two lines eliminate widows and orphans from the document, but may affect typesetting quality elsewhere.

%\pretolerance=10000 % turns off hyphenation

\tolerance=2000 % turns off hyphenation
\emergencystretch=10pt % turns off hyphenation


%  The following changes the Chapter Title format 

\titleformat{\section}{\raggedright\large\sffamily\bf}{\thesection}{1em}{} %formats the section titles 

% for a bit more fancy chapter and section titles use the following 12 lines:
\renewcommand{\thechapter}{\arabic{chapter}} 
\titleformat{\chapter}[display]
{\bfseries\Large}
{\filleft\MakeUppercase{\chaptertitlename} \Huge\thechapter}
{4ex}
{\titlerule
\vspace{2ex}%
\filright
}%
[\vspace{2ex}%
\titlerule]
\renewcommand{\captionfont}{\sffamily}{\small}
\renewcommand{\captionlabelfont}{\bf}

\begin{document}

\onehalfspace
