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。

弹性半空间；本文用线载荷积分方程法研究嵌在弹性半空间的刚性变直径圆轴的轴对称扭转。利用将"半空间的点环力偶"这一虚的基本载荷沿对称轴的圆轴区间中分布就能使本问题归结为一个一维的非奇异的Ferdholm第一种积分方程，且很易用数值求解。文中给出刚性圆锥，圆柱，圆锥柱嵌在弹性半空间的扭转的数值计算的例并和他人的已知结果相比较。

One flush end-plate external joint under monotonical loading and the other four joints under cyclic loading were tested. Failure modes and the effects of reinforcement ratio and concrete in column flange were synthetically considered during cyclic loading. Results of the experiments show that external flush end-plate composite joint also have quite hysteretic behaviors, better strength resistance and stiffness that are worth to promotion in seismic area.Based on experimental results and plastic analysis simplified formulas on moment resistance of semi-rigid composite joints were introduced.
