With respect to this problem, become bit of explanation to everybody, PR is Gu Ge a search engine evaluation to the importance of the website (everybody knows, excuse me is not burdensome), want to accomplish 3 months left and right sides, ability calls significant link, just can increase a website at most otherwise collect, and the time that make a station is not 9 months have PR, of course this is a few circumstance only, also have do a station to be less than March have very tall PR, sure we are not the ascarid inside their abdomen, what do not know they are used is what method (even the attention that somebody gets a government to stand), moral problem remains examine and verify!

就这个问题，给大家做点解释，PR是谷歌搜索引擎对网站的重要性的一个评价，要做到3个月左右，才能称为有效的连接，不然只是最多能增加网站的收录，而且做站时间不是一两个月就有PR的，当然这只是少数情况，也有做站不到3月的就有很高PR的，必定我们不是他们肚子里面的蛔虫，不知道他们用的是什么方法(甚至有人搞政府站的注意)，道德问题有待审核！
