Mercury is in many ways similar to the Moon: its surface is heavily cratered and very old; it has no plate tectonics.

水星在许多方面是相似的月球：其表面严重坑和非常古老的，它没有板块构造。

From a cosmic perspective, the impact of Comet Shoemaker-Levy 9 into Jupiter was unremarkable: the cratered surfaces of rocky planetary bodies and satellites already bear testimony that the solar system is a shooting gallery.

从宇宙的观点，修梅克–李维9号彗星撞击木星是件小事：岩石态行星与卫星凹凸不平的表面，早已说明了太阳系就像个靶场。

Its surface is heavily cratered. Its most impressive feature is perhaps the 800-mi (1,300-km) Caloris Basin, formed by a huge meteorite impact.

它的表面布满陨星坑，给人印象最深刻的也许是它半径达1，300千米的卡路里盆地，是由一个巨大的陨石撞击而成。

Some of the plains are heavily cratered while others are not.

不过也有有很多撞击坑的平原。

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。
