The researchers estimate that there also was about a 70% probability that the prominent Tycho crater on the moon, formed 108 million years ago and measuring about 85 kilometres across, was also carved out by a remnant of the earlier asteroid collision.

研究人员估计，月球上著名的第谷陨石坑形成于1.08亿年前，直径约85公里，也是那次较早小行星碰撞造成的。这种可能性为约70%。

One little prince from a new asteroid in the solar system left because its beauty and naughty. He traveled around various planets. He recognized the king, the vaunter, the drunken men, the businessmen and geologists. At last, he came to the earth, establishing a good relationship with the fox and deriving the essence of life. In the fairy tale, we appreciate sorrow and joy with the little prince and recall the details of their neglected episode.

一个来自太阳系中某颗小行星的小王子，因为和他那美丽，骄傲的玫瑰闹了别扭，便只身出走，在各星球间游历，见识了国王、自负的人、酒鬼、商人、点灯人和地理学家；最后，他降临地球，在这里同狐狸建立了友谊，并且得到了人生的真谛……在童话里我们跟着小王子一起体味忧伤和快乐，回想生活里曾一次次被自己忽略的细节片段，被长大了的我们弄复杂的问题，那些来去如风，经过我们生命的人们。

According to our present broadcasting situation,the thesis proposes using new technology to update and reform the present HFC. It also suggests broadcasting using self-advantage and arranging EPON in order to win the supermarket.

论文从我国广电的现状出发，结合实际，积极倡导采用新技术更新、改造我国现有的HFC网络；倡导广电现阶段利用自身优势，部署EPON网络来赢取市场。

A new general kinetic equation was derived in which the effect of the removal of condensation water was taken into account completely, and was applied to the polyesterification kinetic study of AA/HPHP and AA/NPG. It was found that the reaction order of self-catalyzed polyesterification was not constant. For these polyesterifications, the reaction order was 2.5 at a low temperature, while 3.0 at a high temperature.

考虑缩合水的排除对反应体系的影响，用体积浓度单位推导出一个新的聚酯反应总包动力学方程，并应用到AA/HPHP和AA/NPG两个聚酯化反应的动力学研究中，研究发现，自催化聚酯反应的反应级数并不是固定值，对于AA/HPHP和AA/NPG两个聚酯化反应而言，低温时反应级数为2.5，高温时反应级数为3.0。
