If we consider a space uniformly filled with masses, as, for example, our space is filled with stars, galaxies and clusters of galaxies, we must conclude that, apart from localized large curvatures near particular stars or galaxies, space should possess an overall curvature due to the combined effect of all the masses- a regular tendency to curve uniformly over large distances.

如果我们考虑一个空间，被不均匀的质量块填充着，比如说，像我们的空间，被恒星、星系、和星系团填满，我们得出这样一个结论：除了局部在特殊的恒星或星系附近曲率很大的地方外，由于所有的质量块共同作用，空间应该有一个总曲率-一个在远距离上连续而不均匀的弯曲的趋势。

The program is good be about to begin to come true after my website, through the effort of a week, the structure of whole website came out, repass the test of period of time, basic function was finished, in April 20 I registered a domain name.cn, but the domain name that people says Cn does not use SEO to search (those who hear, do not know to whether be true), be in then in April 24 I registered a new domain name.com again, original plan buys a good space, but still hate to part with, after all fund is limited, but I am quite lucky still, sought a cheap space, and rate is quite good, also knowing because of me the space is speed also can affect a website to rank.

规划好我的网站后就要着手去实现了，经过一个星期的努力，整个网站的结构出来了，再经过一段时间的测试，基本的功能都完成了，4月20我注册了个域名。cn，但别人说cn的域名不利用SEO搜索，于是在4月24我又注册了个新的域名。com，本来打算买个好的空间的，但还是舍不得，毕竟资金有限，但我还是挺幸运的，找了个便宜的空间，而且速度都挺不错的，因为我也知道空间是速度也是会影响网站排名的。
