Said Google cheerly, say Baidu besides this uncle, anyway does not collect my station namely, it is depressed very, I analyse main reason likelihood the home page with respect to me is heavy directional, have code of a few frame again, do not collect all the time so, this uncle is served really hard, I also was mentioned above, I am a typical double-faced case, when each stationmaster makes a station after but must not use heavy directional etc similar go against collected code!

兴高采烈的说完了google，再说说百度这个大爷，死活就是不收录我的站，很是郁闷，我分析主要原因可能就我的首页是重定向的，再有一些框架代码，所以一直不收录，这大爷真难伺候，上面我也提到了，我是个典型的双面例子，以后各位站长做站时可千万不要用重定向等类似不利于收录的代码！

Since the B-spline is a locally supported function, the smoothing formula can be strictly limited in a neighborhood of each point. The smoothing surface defined by the smoothing formula has the same convexity as that of the original image.
