The shock brigade burned the earth and got to the appointe 原文:The shock brigade burned the earth and got to the appointed position in 30 minutes.

原译：那突击队在地上放了一把火，在30分钟内赶到了指定阵地。辨析：从字面看，burn the earth是&烧地&，原译者加了一点工，译成了。。。

A tunneling machine for producing large tunnels in soft rock or wet, clayey, unconsolidated or bouldery earth by simultaneously detaching the tunnel core by thermal melting a boundary kerf into the tunnel face and forming a supporting excavation wall liner by deflecting the molten materials against the excavation walls to provide, when solidified, a continuous wall supporting liner, and detaching the tunnel face circumscribed by the kerf with powered mechanical earth detachment means and in which the heat required for melting the kerf and liner material is provided by a compact nuclear reactor.

&…一个在软岩石，或湿的、粘土状的、疏松的，或巨砾泥土中挖掘隧道的隧洞掘进机，用先进的以上升暖气流进行隧道核心分离，将边界切口熔入隧道面，同时通过使偏倚在隧道壁上的熔融物料在凝固时提供一个连续墙来支持衬垫，形成一个支持挖掘的墙壁；破碎在切口周围划了界限的隧道核心-用有动力的机械土地分离的方法，在隧道核心中，需要如此操作的热力以及衬垫物料由一个小型的核反应堆提供……&

Caspar : That's right, but it was specifically caused by one part of the earth's crust colliding with another deep inside the earth.

卡斯珀：不错，但更确切的说法，是地壳的一块和地球深处的一块相撞，引起海啸。

Objective\ Study the contents of rare earth elements in normal fetal kidney and cerebella, and provide base data for the levels of rare earth elements in different phase o f human development.

目的 测定深圳市正常中期引产胎儿肾脏和小脑中多种稀土元素的含量，为研究人类生命不同阶段稀土元素水平提供基础资料。

The reason of the form of salt lake is disaster and the movement of the earth's crust,Qinghai-Tibet plateau was one part of ocean in the past,by long-term movement of the earth's crust,the surface was raise to be the biggest plateau in the world,as a result,seawater had been left in some bottomland then forming salt lakes and ponds,Chaka Salt Lake was one of them.

盐湖的形成是由于灾难或地壳运动，青藏高原从前是海洋的一部分，经过长期的地壳运动，这块地面抬起变成了世界上最大的高原，结果海水留在了一些低洼地带形成了许多盐湖和池塘，茶卡盐湖就是其中一个。

The results show that the rare earth element Ce can codeposit with cobalt-base alloy, and with increase of mass added of Ce in solution, the content of Co, Ni, Ce in alloy increases and the content of B decreases. Ce can increase plating rate of alloy in some range of content. The rare earth makes deposition potential mve in positive direction and polarizability decrease.

结果表明，在水溶液中稀土元素Ce可以与钴基合金实现共沉积，且随着镀液中Ce的浓度的增大，合金镀层中Ce、Co和Ni的含量逐渐升高，B含量降低；且Ce在一定范围内能够明显提高合金的沉积速度；稀土还使Co-Ni-B合金的析出电位发生了正移，减小了极化度。
