I like to use gmail to manage my other email accounts. But sometimes gmail will mess up and get some old emails into inbox, and unread emails will be buried in those endless gmail threads. I googled a useful tip that can only show those unread threads in Inbox. Put it here in case I will forget.
Just copy and paste on the gmail search box:in:inbox + is:unread

像(1-1)这样的公式要用subequations,例如:
\documentclass{article}
\def\sub{\renewcommand{\theequation}{\theparentequation{}-\arabic{equation}}}
\usepackage[leqno]{amsmath}
\begin{document}
\begin{subequations}
\sub
\begin{equation}
\int_a^bf(x)\mathrm{d}x=F(-F(a))\label{a}
\end{equation}
\begin{equation}
\int_a^bf(x)\mathrm{d}x+abcd=F(-F(a))\label{b}
\end{equation}
\end{subequations}
Equation \eqref{a} and \eqref{b}
\end{document}
如果用\def\sub{\renewcommand{\theequation}{\theparentequation{}.\arabic{equation}}},显示:公式(1.1)
去掉\sub,显示:公式(1a)
