问题1：生成不带编号的具有悬挂缩进的参考文献格式
想人陪的老师：使用bibitem生成的文献
原来的参考文献样式以及代码如下所示：
要生成不带编号的具有悬挂缩进的参考文献格式
添加第一部分代码即可：
makeatletter renewcommand@biblabel[1]{} renewenvironment{thebibliography}[1] {section*{refname}% @mkboth{MakeUppercaserefname}{MakeUppercaserefname}% list{@biblabel{@arabicc@enumiv}}% {settowidthlabelwidth{@biblabel{#1}}% leftmarginlabelwidth advanceleftmarginlabelsep advanceleftmargin by 2em% itemindent -2em% @openbib@code usecounter{enumiv}% letp@enumiv@empty renewcommandtheenumiv{@arabicc@enumiv}}% sloppy clubpenalty4000 @clubpenalty clubpenalty widowpenalty4000% sfcode`.@m} {def@noitemerr {@latex@warning{Empty `thebibliography' environment}}% endlist} makeatotherbegin{thebibliography}{99} bibitem{Ref1}% Format for Journal ReferenceC.L.

使用高贵的电话的就把想人陪的老师的那些都删除
代码：
注意必须有.bib文件，不然调用natbib宏包会报错：

当然有时候有.bib文件也会报错，那么检查
Follow these steps:
1.Delete the .aux and the .bbl files
2.Do your changes (in the bibliographystyle or in any option of natbib)
3.Run LaTeX
4.Run BibTeX
5.借鉴与这里
6.点击打开链接http://tex.stackexchange.com/questions/54480/package-natbib-error-bibliography-not-compatible-with-author-year-citations
另外不同行间距的文献格式，通过参数修改得到
问题2：将正文中显示编号的参考文献改为显示作者加年份的表达方式
不同的引用命令得到不同的正文的引用样式：
注意需要调用natbib宏包才能开启这个大招~
作者缩写(年份)
(作者缩写,年份)
要将作者加年份的引用方式改为编号的，又需要别的方法，反向操作不管用~暂时不想整理
