try +^http://news.buaa.edu.cn/*
This should not be the reason. Your regex fits on urls starting with: http://news.buaa.edu.cn http://news.buaa.edu.cn/ http://news.buaa.edu.cn// http://news.buaa.edu.cn/// ...
The only thing I would try is to escape some caracters to make it more correct. A dot means every possible sign. Better:
+^http:\/\/news\.buaa\.edu\.cn
Did you make enough rounds, to get the wanted depth? With every crawl you only fetch the already known links.
