目录下会生成bb.aux、bb.log、bb.pdf三个个文件。bb.aux有用。 bb.pdf文件内参考文献，没有正确显示出来。只显示"?"，表明还没有引用。
2. bibtex bb
This is BibTeX, Version 0.99d (TeX Live 2014/dev) The top-level auxiliary file: bb.aux The style file: alpha.bst Database file #1: tex.bib
生成 bb.bbl，bb.blg两个文件。这两个文件都是字符文件，可查看。其中*.bbl内容就是要插入到*.tex中去的。注意命令中，文件名字是bb，而不是bb.tex。

无新文件生成，但查看bb.pdf，其中的参考文献已经显示出来，但正文中对参考文献的引用依然显示为"?"，没有正确（产生交叉）引用。

此时，用evince bb.pdf查看生成的pdf，已经是一份正式的档了。
总结：
为了编译出出正确的pdf文件，需要执行4条命令完成整个编译过程。
留意：
只试了英文，没试中文。中文需要cjk等支持，没有实验。
参考文献条目内的空格似乎过大。不知是否有插件可以显示得更好。
