Study on the Mechanics and Tribological Behavior of POB Filled PTFE Composites 聚苯酯填充聚四氟乙烯复合材料的力学及摩擦学性能研究
Experimental results show that POB reduces the friction coefficient and increases the wear resistance of PTFE. 结果表明,添加POB降低了PTFE的摩擦系数,提高了PTFE的耐磨性。
Objective To investigate the proliferative and osteogenic activity of periosteal osteoblasts ( POB), calvarial osteoblasts ( COB) and bone marrow stromal cells ( MSC) from the same embryo. 目的比较从同一胚胎来源的骨膜成骨细胞、颅骨成骨细胞和骨髓基质干细胞的分裂增殖能力和细胞的功能状态。
