Block-copolyimide film from pPDA/ODA-PMDA was studied by TEM, SEM, PLM, ultra-deep three-dimensional microscope, TMA, and WAXD, which showed that the extensile strength and modulus of b-PI film were higher than that of irregular copolyimide film. It was also revealed that there was a large amount of crystallite formed in b-PI film, which was mainly attributed to its chain structure: rigid pPDA-PMDA chains were easy to form crystal nucleus because of phase separation, based on which semi-rigid PMDA-ODA molecular chains began to crystallize.

以pPDA／ODA-PMDA型嵌段共聚酰亚胺薄膜为对象，借助TEM、SEM、PLM、超景深三维显微镜、TMA、WAXD等手段，研究结果表明：b-PI薄膜的拉伸强度、弹性模量均高于无规共聚酰亚胺薄膜；b-PI薄膜中形成了大量的微晶，这是由于刚棒状的pPDA-PMDA分子链段因相分离容易形成晶核，然后半刚性的PMDA-ODA分子链段以PMDA-pPDA为晶核进行晶体生长造成的，而且ODA-PMDA分子链的结晶和酰亚胺化反应基本上是同步进行的。

The unoperated sides of the treated animals also served as controls. Six normal rats were treated as normal control group. Three different siRNA plasmid solution containing RC2-Ⅰ, MAFbx-Ⅱ, CON (50μl , 0.8μg/μl)was injected and transfected by electroporation as methods mentioned above, respectively. The changes of RC2 and MAFbx mRNA levels and RC2 protein levels after 3 days were determined by real-time quantitative PCR and Western blot, respectively. On postoperative 2, 3 and 4 weeks, the rate of wet muscle weight preservation, mean diameter of muscle fiber and mean cross-section area of muscle fiber and muscle protein content were checked and then compared between group CON and group RC2 or group MAFbx, respectively. The differences between groups were analyzed by one-way ANOVA. Ultrastructural changes of muscle fiber were observed at 2, 3, 4 weeks postoperation.Results GFP plasmid was efficiently deliverd into muscle by electroporation and robust GFP expression in muscle could be observed more than three weeks. Histology shows that injected plasmid DNA diffuses extensively in muscle tissue.

The silica surfaces polished with ion beam of 400ev energy and 100mA density in 35°incident angle for 2hrs was found to have a roughness less than 0.5nm . The SFM was also used to measure the surfaces to be bonded by SAB method and the deformations of the surfaces during contact each other. The micro roughness of the surfaces was found to produce great effect on the SAB strength. The rougher the surfaces are, the weaker the bonding forms.
