Under the three body abrasive wear, the cutting is main reason of wear of the hard materials (3M and 2M). It is an important wear form of material 4M and several austenitic manganese steel at high load condition. b. The plastic materials form the block debris after deforming many times, forming the block-shape debris is the major waar form of this kind of material under several given wear conditions.

在三体磨粒磨损条件下，切削是造成编号为2M和3M等硬质材料磨损的主要原因，也是4M和几种奥氏体锰钢在高载荷下磨损的重要形式；块状屑的形成是塑性较好的材料在各种磨损条件下磨损的主要形式。

The sizes of the self-assembly micelles of the amphiphilic block copolymers and the effects werestudied by dynamic light scattering and UV-visible spectrophotometer. The micelle sizes werelargely influenced bythe hydrophobic chain content in the copolymer, the properties of the solvent and the copolymer concentration in the organic phase. The morphology of the micelles was investigated by transmission electron microscopy. Theresults showed that the micelles appeared spheres with inner core and outer shell. The critical association concentrations were determined by pyrene monomer fluorescence probe technology. The degradability of copolymer was studied by the loss of the intrinsic viscosity in the degradation process. The results indicated that the degradation rate of PECL was slower thanthat of PELLA and PEDLLA. The stability of the copolymer micelle dispersion was examined by measuring the critical flocculation concentration, which gradually decreased with increasing the content of thehydrophobic chain in the copolymer. The rheological results showed thatthe viscosity ofthe micelle dispersion with higher content of PEG segments was firstly decreased and then increased with the increasingthe temperature. Otherwise, the variation of viscosity was irregular. The viscosity of the micelle dispersion increased with the increase of the electrolyte (Na 2SO 4) concentrations. Polymer micelles paclitaxel was prepared by self-emulsification/solvent evaporation method and solid dispersion technique with amphiphilic block polymers as the carrier material.

运用动态光散射和紫外分光光度计研究了两亲性嵌段共聚物自组装胶束的粒径及其影响因素，结果表明，自组装胶束的形成机理受制备方式的控制，胶束的粒径随着共聚物相对分子质量或疏水嵌段相对分子质量和有机相中共聚物浓度的增大而增大，随着有机溶剂的水溶性的增强而减小；采用透射电镜观察胶束的形态结构，发现胶束呈具有核壳结构的均匀球形；采用芘荧光探针法测两亲性嵌段共聚物的临界聚集浓度；通过降解过程中共聚物特性粘度的变化研究两亲性共聚物的降解性能，发现与PELLA和PEDLLA的相比，PECL 降解速率较慢；随着共聚物中疏水嵌段含量的增大，纳米分散液的稳定性逐渐下降；PEG含量高的PEDLLA纳米分散液随着温度的升高，纳米分散液的粘度先下降然后增大，反之，没有规律性，且随着电解质Na 2SO 4浓度的增大，体系粘度增大。

Through once again on the M14-6-X55 to take measures to reduce the balance of the block, the well balanced conservation block 2, balance rate from 60% to 87.5%, saving 28 degree day, the pilot was a success.

通过再次对M14-6-X55采取减少平衡块的措施后，该井节约平衡块2块，平衡率从60%上升到87.5%，日节电28度，试验取得了成功。

We'll go through the important parts block by block in detail.

我们将通过的重要组成部分，详细的块体块。

Block: block of data, which is a subset of the piece specified by index.

piece消息是一个变长的消息，X是的长度。

"In economic terms there is no reason to block Chinese ownership of U.S. assets just as there was no reason to block Japan from buying U.S. assets in the 1980's," Mr. Reich said.

&就像上世纪80年代没有理由阻止日本购买美国资产一样，没有任何经济术语能够限制中国拥有美国资产，&Reich先生说道。

Early this year the Chinese government undertook a bold step: They began systematically bulldozing the Old City block by block and moving the inhabitants into a new compound on the edge of town.

今年早些时候中国政府又有大胆的新举动：他们开始一片区域一片区域地铲平这座古城，居民被迁往这座城边缘地带的复式居民区。
