MPH plastic magnetic pump complies with JB/T7742-1995Standard for Small Magnetic Transmission Centrifugal Pump. Its flow-through parts adopt PPS with corrosion resistance to most acid, alkali and salt (except oxidable acid like strong sul-furic acid, nitric acid and aqua regia). Its performance is close to the chemical performance of F4, which can resist to most organic solvents under 100℃, especially to the mixture of gas and carbinol. Thus it is an ideal pump for acid and alkali industries.

MPH型塑料磁力泵符合JB/T 7742-1995《小型磁力传动离心泵》标准，过流部件采用聚苯硫醚，不受大多数酸、碱、盐的侵蚀(除氧化性酸如浓硫酸、硝酸和王水等)，其性能接近于聚四氟乙烯的化学性能，在100℃以下能耐大多数有机溶剂，特别能耐汽油和甲醇的混和液，是酸碱工业中的理想用泵。

The predominant wear mechanisms of Cu-nanosized TiB2 in-situ composites are plastic flow and oxidational wear at higher sliding speed.

在较高滑动速度下，塑性流变和氧化磨损为其主要磨损机制。

Despite his much-publicised eccentricities -- the plastic surgeries, dangling babies out of hotel windows and taking his kids shopping at 3am -- Jackson was a devoted father, said Oxman, and his children "are his greatest work".

尽管他有着所报道的那些怪癖---外科整容，在宾馆窗户前晃孩子，半夜三点带孩子逛商店----但是杰克逊是一个无私的父亲。他的孩子才是他最伟大的作品。奥克斯曼说。

The mechanical properties of coal filled polymer composites The mechanical properties of coal/PP composites were investigated, and the effects of coal rank, particle size, surface modification of coupling and alkylation were discussed. The results show that the anthracite and bituminous coal all can be used as filler of plastic after pretreatment of part devolatilization and surface modification; The modulus of composites increase with the content of coal filler; The coupling agent is of no effect for reinforcing the coal/PP composites, except that there are new oxygenous function group forming on the surface in the process of pulverizing; The F-C alkylation reinforce coal (under 10μm)/PP composites obviously.

4煤填充高分子复合材料力学性能超细煤粉填充聚丙烯复合材料力学性能的研究结果表明，烟煤和无烟煤经过脱除部分挥发分的预处理后，都可用于与塑料共混制备复合材料；偶联剂改性对低变质程度烟煤/聚丙烯复合材料的力学性能基本不起改善作用，而对于经气流超细粉碎后的小粒径高变质程度烟煤及无烟煤则有一定的增强作用；烷基化改性在煤表面接枝了烷基，使平均粒径小于10μm的煤/聚丙烯复合材料拉伸屈服强度普遍提高，煤填充高分子复合材料可在较高含煤量情况下维持良好的力学性能。

The feasibility of the equipment to measure Tg of amorphous powder is verified with a lot of experimentl results.The Tgs of some typical starches such as corn, pachyrhizus, buckwheat and pea in different water content are obtained by TDA. It is found that the water has plastic effect on starch and the Tg of starch decreases with the increase of water content. Through this study a quantitative expression is established to relate Tg and water content, and it is testified with experimental results for the sticky rice starch with different water content.
