超细的

According to the classifing method of Geldart,ultrafine powders belong to group C particles.It is difficult to fluidize because of such cohesiveness.However,it was discovered recently that some powders can be fluidized smoothly through forming larger agglomerates at high gas velocity,and the fluidization quality of some powders can be improved by external force.

按Geldart的分类法，超细粉属难流化的C类颗粒，但近年来的研究表明，某些超细粉在高气速下可以形成较大的聚团，而以聚团形式实现平稳流化；对在高气速下难以流化的超细粉，人们通过引入外力场等方法来改善其团聚特性，提高流化质量。

The results shows that in the binary system, with the increase of reactive powder, the viscosity and relative degree of compaction of fresh paste increased whenas the fludity decreased; the strength of PRC of C+UPFA+SF is high than that of the C+UPFA and C+SF, and the strength of RPC related to the cementitious materials' relative degree of compaction and fluidity as in C+UPFA+SF system, when the relative degree of compaction was 0.699 and the fluidity was 182mm, the 7d compression strength of RPC was 150.4MPa.

实验结果表明：(1)双掺硅灰和超细粉煤灰，随活性粉末掺量的增加，新拌浆体的黏度增加，流动性下降，相对密实度提高；(2)双掺硅灰和超细粉煤灰的RPC强度远高于单掺硅灰时的强度；(3)RPC强度与体系中胶凝材料的相对密实度和流动度有关，复掺硅灰和超细粉煤灰，当密实度为0.669，流动度为182mm时，其RPC的7d抗压强度高达150.4MPa。

A novel submicron particle agglomeration technique was developed to control the emission of submicron particle.The submicron particles were agglomerated by an agglomerant solution which was sprayed into the inlet of electrostatic precipitator, thus, the agglomerated submicron particles could be captured by the dust collecting equipment.

提出一种燃后区烟尘团聚促进新方法，通过在燃后区烟道喷射团聚促进剂，利用絮凝理论，增加超细颗粒之间的液桥力和固桥力，促使超细颗粒物团聚长大，进而被现有除尘装置捕获，减少超细颗粒的排放。

Results The intramural capillary lymphatics of rat's rectum were observed in deep lamina propria of tunica membrane and the dermal papilla layer of anal pectin. The intramural capillary lymphatics and lymphatics were both observed in tela submucosa, reticular layer, hypodermis and intermuscular and serosa. The capillary lymphatics in rectums' wall have the similar ultrastructure feature to normal ones. Three kinds of endothelial cells junctions are overlapping junctions, embedding-junctions and end to-end-type junctions. About 21% of cell-junctions are opening types. There are normal organelles and many vesicals in the endothelial of capillary lymphatics.
