分析：
1.class FaultyInfoHandler(tornado.web.RequestHandler):
--FaultyInfoHandler继承tornado.web.RequestHandler
2.def get(self):
--self 指的是FaultyInfoHandler（PS：我是这么认为的，有待确认）
def get(self) 指重新定义get方法，像get、post这类方法原本在tornado.web.RequestHandler是存在的，这里是重定义
self.render("faultyinfo.htm", lists=info) 中render方法在FaultyInfoHandler没有重定义，所以用的是继承于tornado.web.RequestHandler定义的render方法
3.def post(self):
--重新定义post方法，加载页面时，默认调用的是FaultyInfoHandler中的get方法，在htm中采用form表单指定post方法时才会调用post方法，htm中使用如下面代码所示：

通过表单的方法：form_info.method form_info.action form_info.submit
4.self.write('<META HTTP-EQUIV=REFRESH CONTENT=0;URL=/View/faultyinfo>')
--重新加载/View/faultyinfo页面
5.self.write("<script language=javascript> top.location='/';</script>")
--重新加载整个页面（缺少说明！！！）
