latex 左双引号的输入法

在键盘上左上角第二排，Esc键下方，数字键1左侧，输入两个就是左双引号了。

[Latex]no title page after \maketitle

Usually in latex
\maketitle
will create a new page after the commands, for example, if you want to put a title page, you can use that command.
But if you want your article start right after the abstract instead of putting it
on another page, you can do this in the document class.

\documentclass[12pt,aps,prb,preprint,notitlepage]{revtex4}
