Construct PLXRN-IL-1Ra and PLXRN-IL-10 vector, lapine synoviocytes were first transduced in culture by retroviral infection. The genetically modified synovial cells were then transplanted by intra-articular injection into the knee joints, assay of joint lavages confirmed that the gene expression was not lost after 14 days of transfer. Knees receiving the hIL-1Ra had significantly reduced cartilage breakdown. Delivery of the hIL-10 was less effective, When both genes were used together, there was a greater inhibition of cartilage breakdown and a considerable reduction of cartilage matrix degradation.

With the dose of 7.04 mC/cm2, ODT/Au will become a more strengthened structure and then form a negative resist in the correlation with cross-linking from alkyl matrix, partial breakdown of S-Au bonding and surface adsorption by air-borne species. Thus, it can obtain a gold pattern via gold-etching process. Besides, as a result of massive breakdown of alkyl matrix and S-Au bonding from ODT/Au under irradiation with doses of 64.06 and 128.13 mC/cm2, ODT SAMs would form a loose-packed structure on the gold substrate. The ODT/Au becomes less resistive for gold-etching and a positive gold pattern would form after gold-etching.

结果发现：以50 eV 低能量电子在照射剂量7.04 mC/cm2微影并曝露於大气后，受到来自於ODT/Au碳链间的交联、部分的S-Au键结破坏以及照射后立即曝露大气所吸附於表面的碳氧化物种的共同影响下，ODT SAMa於Au膜基材上将形成更紧密复杂的结构而作为负型阻剂，经后续湿式蚀刻15分钟后将显影出来Au的负型图案；当提升照射剂量至64.06及128.13 mC/cm2后，由於ODT/Au上碳链及S-Au键结的大量破坏，将使ODT/Au结构不能稳固且紧密地排列於Au膜基材上，显影时Au蚀刻液将容易穿过ODT SAMs抵达S/Au界面而移除Au，而形成正型图案。

The influence of impulse voltage waveshape on particle-initiated breakdown voltage of a GIS system in SF6 and SF6/Air mixtures is reported. The results are compared with the characteristics of air gaps. For the SF6 gaps, breakdown voltage depends on wave-front duration but almost independs on wavetail duration. For the gaps in SF6/Air mixtures, the influence of impulse waveshape also depends on SF6 contents and electrical field non-uniformity

作者研究比较了正极性冲击电压波形对SF_6、空气、SF_6/空气的 GIS 电极装置由固定导电微粒引发的击穿电压的影响，结果表明：SF_6间隙的击穿电压受冲击电压波前时间长短的影响较大，而与波长的关系不大，当采用SF_6/空气混合气体时，则这种影响随SF_6含量增大而愈明显，并与电场不均匀程度有关。
