At first,the curve of charge distribution,ionizable state of nonisothermatity sphere,Was obtained by computer to calculate ionized state according to distribution data of temperature and dinsity within Earth. Secondly,the pussibility of microgravitational testonosphere,Within the isothermality sphere,was found by balance between pressure and volumetric forcein Earth's interior.The thickness is 1 000 km or so.Finally,the result come into commom use various geophysical process withi...

首先依据地球内部温度和密度不均匀分布数据，用计算机计算它的电离状态，得到非等温分层电离状态的电荷分布曲线；其次从地球内部存在的流体压力与两类体积力：重力和静电力的平衡方程讨论中，发现在某一等温层内可能存在微重力构造圈，其厚度约为1000km左右；最后在地学研究向整体化和深部化发展趋势下，预期这个结果将有助于理解地球深部发生的各种物理过程且与地震S波在核－幔之间层中消失观测事实相一致。

The experimental results showed that SiC ultrafine powder was synthesized at 1500℃for 120 minutes by used rare earth lanthanum as additive. Its primary particle size was about 100nm and aggregated particle size was about 360nm and the particle shape was regulation, non-aggregation and well dispersibility. While the rare earth ceria used as the additive, SiC ultrafine powder was synthesized at 1500℃for 150 minutes but the particle shape was irregulation and seriously agglomerated and had numerous crystal whiskers.

实验结果表明：以稀土镧为添加剂时，在1500℃×120min合成工艺下，可以合成出一次粒径为100nm左右，二次粒径为360nm的SiC细粉，且SiC粉体颗粒形状规则，无团聚，分散性好；以稀土铈为添加剂时，在1500℃×150min合成工艺下，也可以得到单相的SiC，但SiC粉体颗粒形状不规则，有大量晶须存在，且团聚严重。

The activated hydroxyl of the rare earth complex reacted with the -NCO of the of isophorone diisocyanate,and a new bonding-type rare earth polymer materials was prepared. We studied the optical property, thermodynamic properties of the materials were, and the results obtained show that the materials have high light transmittance and thermal stability as well as good fluorescence properties.

同时利用配合物的活性基团羟基与异佛尔酮－二异氰酸酯中的异氰酸根活性基团进行反应，制备出一种新型的键合型稀土高分子材料，并考察了该材料的光学性能、热力学性能等。

As the Earth-bound scientists toil, Rosetta itself will continue to zoom across our Solar System, next swooping again by the Earth in 2009 November, flying by asteroid 21 Lutetia in 2010 July, and finally landing on comet Churyumov-Gerasimenko in 2014 November.

当科学家在忙碌的同时，罗塞塔号也将继续在太阳系中飞驰，预定于2009年11月越过地球、2010年7月飞越小行星21Lutetia ，并于2014年11月最终降落在 Churyumov-Gerasimenko 彗星之上。

The development of magnetic materials was extremely rapid during the 1990's,when magnetic alloys of the rare earth-3d iron group,such as rare earth permanent magnets,giant magnetostriction materials,giant magnetocaloric materials,magnetooptic materials,magnetic amorphous materials,and nanocrystalline magnetic materials,appeared one by one.

稀土-3d过渡族磁性合金材料，如稀土永磁、巨磁致收缩材料、巨磁热效应材料，磁光效应材料等，以及非晶，纳米微晶磁性材料相继问世。1988年巨磁电阻效应的发现已获广泛应用，如读出磁头、传感器以及磁随机存储器等，并发展成为自旋电子学的新学科。
