latex由于其排版的美观大方，已经逐渐成为专业排版科技论文、学位论文等常用的排版工具，国外大多数的期刊都要求投稿人用latex排版，可见其地位之重要-LaTeX　is a document markup language and document preparation system for the TeX typesetting program. Within the typesetting system, its name is styled as LaTeX. The term LaTeX refers only to the language in which documents are written, not to the editor used to write those documents. In order to create a document in LaTeX, a .tex file must be created using some form of text editor. While most text editors can be used to create a LaTeX document, a number of editors have been created specifically for working with LaTeX.
