In some 2012 doomsday prophecies, the Earth becomes a deathtrap as it undergoes a 'pole shift,' courtesy of an asteroid impact, a rare alignment with the center of the Milky Way, and/or massive solar radiation destabilizing the inner Earth by heating it.

在一些关于2012世界末日的预言中，地球将变成一个死亡陷阱，它将遭受着"轴心移位"，小行星的撞击，和银河系的中心对齐，或是大量的太阳辐射对地球的加热，使地心不稳定。

President Lin Chun-shin pointed out that rock had recorded many past events of the earth in addition to geological changes after many times of plate movements. The decipherable messages were not enough to trace the whole looks of the earth in the past.

林俊兴董事长表示，虽然岩石记录著过往地球所发生的事件，但历经多次的板块动运、地形变迁，能够被解读出来的讯息，并不足以还原过去地球的全貌。

At that time the main danger had come from the Polemarch, and Bean wrote an anonymous letter to a couple of opinion leaders on Earth, Locke and Demosthenes, urging them to get all the Battle School children back to Earth so they couldn't be seized or killed by the Polemarch's forces in the League War.

在那个时候，最主要的危险是来自官员的，而豆子给地球上的两名对立意见的领导者，洛克和德摩斯梯尼写了一封信，建议他们掌握所有战斗学校的孩子带他们回地球，这样他们就不会被国家官僚在联盟战争中所控制或谋杀。

As such, it rejects not only radiometric and isochron dating of the age of the Earth, arguing that they are based on debatable assumptions, but also approaches such as ice core dating and dendrochronology, which make the barest of assumptions of uniformitarianism, and which hint that the Earth is far older than the Ussher-Lightfoot Calendar suggests.

如同这个，不仅拒绝放射性和等时线地球年代测定方法，争论基于可争论的假定，而且采用这类冰核和树木年代学测定，树木年代学使得均变论假定一览无遗和暗示了地球比Ussher-Lightfoot日历更为古老。

The experimental results of cyclic operation indicate that, sulfuric acid concentration in feed solutions decreases and sulfuric acid concentration in dialyzate increases in the operational process, furthermore, rejection ratio of rare earth is very high, and DD can achieve the purpose of sulfuric acid separation from rare earth sulfate solutions.

循环式结果表明，渗析过程中，料液中硫酸浓度不断减小，而渗析液硫酸浓度不断增大，而且由于对稀土具有较高的截留率，扩散渗析法能达到硫酸与稀土有效分离的目的。

The polymer carriers,the immobilization of rare earth compounds,the properties of polymer-supported rare earth metal complex es and their catalytic characteristics in the polymerization of diene was reviewed with 25 references.

对聚合物载体的合成、稀土金属化合物的固定和聚合物载体－稀土金属络合物的性质及其催化双烯烃聚合的特征进行了论述。

The matrix composites for diamond tools were tested with such modern testing instruments and equipments as DTA-7 differential thermal analyzer, JCXA-733 electronic probe and scanning electron microscope, JEM 2000 FX Ⅱ transmission electron microscope, eXL energy spectrometer, and humidity test instrument. The analysis, comparison, and induction of the testing results prove the enhancing effects of the rare earth on the matrix composites: degeneration, micro-alloying, purification, and catalytic activation. The comprehensive function of these effects leads to the decrease in the porosity of the matrix composites and to the increase in such actual indexes as the flexural strength, hardness, and impact ductility of the whole rare earth Fe-based diamond tool materials.

由DTA-7型差热分析仪、JCXA-733型电子探针及扫描电镜、JEM2000FXⅡ型透射电镜、eXL能谱仪以及莱茨2AP高温显微镜材料润湿性测试仪等现代测试仪器设备对金刚石工具材料进行了测试实验，对测试实验的结果进行了分析、比较和归纳，证实了稀土对胎体材料具有变性、微合金化、纯化和催化活化等四大强化作用机理，这些机理的综合作用导致了胎体材料孔隙率的降低和整个稀土Fe基金刚石工具材料抗弯强度、硬度及冲击韧性等实际使用性能的上升。
