Recently,I found the code that cotains the"~\\"
and blank line
always shows the warning imformation "Underfull \hbox (badness 10000) in paragraph at lines"
\documentclass{ctexart}
\usepackage{color}
\usepackage{amsmath}
\usepackage{amssymb}
\usepackage{graphicx}
\usepackage{epstopdf}
\hfuzz=\maxdimen
$(A \pm B)^{-1} \neq A^{-1} \pm B^{-1}$,$(A \pm B)^* \neq A^* \pm B^*$~\\
$|(A^*)^*|=|A|^{n^2-2 n+1}$~\\
\end {document}
I add the code:
\tolerance=10000
\hbadness=10000
\begin{document}
However,fail to solve it!

A paragraph should be ended by leaving a blank line in the input, not with
~\\
. What happens is that an empty line is produced and it's underfull by construction, because it has nothing in it.If you really need a blank line between two paragraph, use
\bigskip
(better yet\medskip
) between them:If you want a vertical space between all paragraphs, consider loading instead the
parskip
package (look at its documentation). Note that “leaving blank lines” here and there is a practice coming from the usage of word processors, where it's very easy to do it (and thus spoil the document's appearance).For your formulas, you should use an alignment environment; if you want (almost) flush left equations, there's the option
fleqn
:Warning
Use none of the following commands:
With them you're basically saying that you don't care about getting good paragraphs. Maybe you don't care, but your readers do.
