目的:采用不同孔径钛铝金属间化合物多孔材料(TAICPM)分离大黄虫丸,探讨经不同孔径TAICPM处理后的大黄虫丸抗动脉血栓形成的作用及机制。方法:选择70只SD雄性大鼠随机分为7组,其中正常组、模型组、对照组各10只,TAICPM组40只:1-5μm组、5-10μm组、10-15μm组、15-20μm组,每组各10只。血栓干重、血小板计数、血栓素B2(TXB-2)和6酮前列腺素F1α(6-keto-PGF1α)作为观察指标,评价经TAICPM分离后大黄虫丸抗动脉血栓形成的效果。结果:①对照组及TAICPM组血栓干重、血小板计数明显少于模型组(P

Tooth stiffness of face gear is one of the components of meshing stiffness of face gear drives. Its resolve can build excellent base for calculation method of meshing stiffness and analysis of dynamic for face gear drives. Based on Buckingham's standpoint, along the length direction of the tooth of face gear, any one of its sections can be considered as a section of rack with varying pressure angle. According to above theory, the tooth form of face gear is simulated successfully. The method of calculation of the tooth's stiffness of face gear is obtained. Compared with conclusion of tooth's st...
