5.Object: To investigate the variance of expression of Paxillin (Pax) in human renal tubular epithelial cells (HKCs) during undergoing tubular epithelial to mesenchymal transition (TEMT) induceded by transforming growth factor β_1 (TGF-β_1) and the result of intervention of protein tyrosine kinase (PTK) inhibitor genistein (Gen).
目的：研究桩蛋白(paxillin，Pax)在转化生长因子β_1(transforming growth factorβ-1，TGF-β_1)诱导人肾小管上皮细胞发生小管上皮-肌成纤维细胞转分化(tubular epithelial tomesenchymal transition，TEMT)过程中表达的变化及酪氨酸激酶(protein tyrosine kinase，PTK)特异性抑制剂金雀异黄素(genistein，Gen)的干预结果。
6.Glass transition of single chain atactic polypropylene,conformational state transition of backbone bond of the polymer were studied by molecular dynamics simulation method through different temperatures,thus validating,developing a new method in characterizing the glass transition of polymers,specially for single chain glassy particles,where the volume of the particle is hard to be determined,without the indicator the glass transition could usually not be obtained

7.The Peierls instability in chain-like substances is re-examined and a stepped Peierls transition theory is developed. This is because the weak inter-chain coupling makes the usual Peierls transition modified: CDW transition and the associated metal-insulator transition occur no more simutaneously but at different temperatures.
重新考查了链状结构材料中的Peierls相变,提出了一种分步Peierls相变理论,原因来于弱的链间耦合导致通常的Peierls相变发生畸变:CDW相变和金属一绝缘体相变不再同时发生,而各出现于不同温度。
8.Based on Petri nets,control variable was added to DWF_net and transition was classified as transition entry and transition body.
工作流描述模型在Petri网的基础上增加了控制变量,并将变迁划分为变迁入口和变迁体两部分。
9.The author modified the Abu-Ghannam and Shaw Transition Model (AGS Transition Model) with ready test data,set out the concept of calculating the transition length with arc Reynolds number and compared the calculated value with the test value.
本文作者利用现有的试验数据对Abu -GhannamandShaw〔1〕转捩模型 (AGS转捩模型 )进行了修正 ,提出了利用弧长雷诺数模型确定转捩区长度的思想 ,并对计算结果与试验值进行了比较
10.We analyze the transition from the current networks to B-ISDN in our country and foreign countries. In the light of our current data communication networks and the technology of data communication:we also analyze the method of the transition from the current networks to B-ISDN,starting from the bottleneck,that is,network interconnect rate,And finally we present the possible method of the transition to B-ISDN.
本文首先分析了国内和国际通信网向B－ISDN过渡的发展状况，针对我国在数据通信网发展中的实际情况，从网络接入的速率瓶颈入手，结合我国主要采用的数据通信技术，分析我国通信网向B－ISDN过渡的路线； 我们给出了向B－ISDN过渡的可能路径的分析．
