Presumably if all life on Earth were extinguished, the Earth's atmosphere would fall back to a persistent equilibrium, and become as boringly predictable as Mars and Venus.

可能要等地球上所有的生命都寂灭之后，地球的大气才会回降至持续平衡状态，变得像火星和金星那样沉闷。

The Brahe theory stated that all of the planets except the earth revolved around the sun, which in turn revolved around the earth. Brahe's assistant, German astronomer Johannes Kepler (1571-1630), used induction to analyze the data collected by Brahe over a twenty-year span. Kepler supported the heliocentric theory by proposing three laws of plant revolution.

在哥白尼思想的影响下，泰革(Tycho Brahe， 1546-1601)在观察的基础上，提出了哥白尼式的地心说︰地球以外的行星都绕太阳转；但太阳及其行星都绕地球转﹗泰革的助手、德国天文学家凯普勒(Johannes Kepler， 1571-1630)用归纳法分析泰革二十年积累的数据，提出了"行星运行三大定律"，支持了日心说。

This earth is ours, it is not the earth of the Brahmin, the Russian or the American.

地球是我们的，它不是婆罗门的地球，俄国人或者美国人的。

Follow both that of text summarize reinforced earth breast wall collapse mode and stability require, the design and calculation method of the introduce adoptive constitutive model research reinforced earth retaining wall.

接着，本文总结了加筋土挡土墙的破坏形式和稳定性要求，采用的本构模型的介绍，研究了加筋土挡土墙的设计与计算方法。

So my parents asked me to carry earth for the brickyard, believing that it would pay me by earth weight I did.

当时正好有一个外村来找活的表叔也要去挑土，父母就让我和他一起去。

In this case,the source of the earth's magnetic field is the current produced by displacement of a double electrical layer's plates appearing on the boundary of the solid and liquid phases of the nucleus (the layer F of Bullen's earth's model).

在这种场合下，地球磁场的本源就是电流，这种电流是由在地核固相与液相边界上的一对带电层的相对运动产生出来的(Bullen地球模型中的F层)。

This invention discloses a new technology for preparing rear earth ionic doped fiber prefabricated rods with DC-RTA technology in a sol-gel method including preparing sol containing necessary doped ions, coating said sol uniformly on the inner wall of the quartz glass tube and burning it under high temperature to coagulate and vitrify them to a doped layer and repeating the above process to form a fiber prefabricated rod by oxygen and hydrogen flame after the doped layer reaches to a designed thickness and the fiber prefabricated rod can be made to various rare earth ionic doped fibers by an ordinary drawbench technology.

本发明属于光纤制造和光纤激光技术领域，具体公开了一种利用溶胶凝胶方法中的DC-RTA技术制备稀土离子掺杂光纤预制棒的新工艺。该工艺步骤包括预先配制好含有所需掺杂离子的溶胶，将该溶胶均匀涂覆在石英玻璃管的内壁后高温灼烧，使之凝结并玻璃化为一层掺杂层。反复上述涂覆灼烧过程，在掺杂层达到设计厚度后由氢氧焰高温收棒形成光纤预制棒。该方法所得到的光纤预制棒可以通过普通拉丝工艺拉制成各类稀土离子掺杂光纤。
