Objective To study the role of fibroblastic stromal cells in aseptic loosening.

目的 研究成纤维母细胞样基质细胞在人工关节置换术后无菌性松动中的作用。

To investigate the presence of specific adhesion activity, the mrkD adhesin gene of the established type 3 fimbriae expression system was replaced respectively by each of the fimbrial adhesins. Transmission electron microscopy and western blot analysis revealed that most of the recombinant type 3 fimbriae expressed and assembled properly.

位於纤毛末端的黏附蛋白为决定细菌黏附专一性的主要因子，为了测试黏附蛋白的活性，我们进一步以过去建立的第三型纤毛表现系统为平台，将MrkD黏附蛋白基因分别置换为kpa、kpb、kpc、kpd、kpe、kpf或kpg的黏附蛋白基因，并经西方墨点法确认这些重组第三型纤毛的结构蛋白的表现和组装正常。

The phenol in the wastewater from fluorobenzene production was recovered by replacement extraction with TBP as extractant and NaOH aqueous as reverse extractant.

以磷酸三丁酯为萃取剂、NaOH水溶液为反萃剂，采用萃取置换法回收处理氟苯生产废水中的苯酚。

At the same time, the K, G, Vp, and Vs of forsterite decreased too because of density decrease 3.0% caused by H atoms replacing Mg atoms in the crystal. Water also increases the total energy of the forsterite system, i. e. the crystal stability and the power of bond were reduced at high pressure and temperature.

在常温常压下，2个氢原子置换1个镁原子会使镁橄榄石的密度降低3.0%，是波速及弹性模量减小的原因，同时使镁橄榄石体系的基态总能增加，降低矿物的稳定性和键之间的强度。

In this study, we first synthesize a conducting polymer, P3HT, via Grignard metathesis method. And we functionalize the polymer chain end of P3HT into vinyl group. After characterize from 1H NMR spectroscopy, we use the end functionalized P3HT to proceed coupling reaction with P2VP anion.

为了达到这个研究目的，我们先利用格林纳置换法合成导电高分子P3HT，并将其尾端乙烯化，在经核磁共振仪确定结构后，利用此尾端乙烯化之P3HT与P2VP阴离子反应进行接合。
