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。

Results and conclusion: The expression of NF-κB p65,TNF-α and IL-8 was higher than that of other groups.They may play a vital role in parturiens with PRD associated with IAI .In the placenta tissues of the mice with PRD associated with simulating IAI, after an application of PDTC, TNF-α and IL-8 decreased and the gestion time could maintain longer.

实验主要结果与结论如下：1、通过检测足月妊娠和早产胎盘组织中NF-κB和细胞因子的表达，发现在感染性早产时，NF-κB和细胞因子TNF-α、IL-8的表达增加，提示NF-κB可能为感染性早产分娩启动的关键环节，炎性细胞因子TNF-α与IL-8在感染性早产中起重要作用。

Each letter is used exactly once.1{"ABC","FED","GAI"}"ABCDEA"Returns: 2Once we get to the ''E'', we can choose one of two directions for the final ''A''.2{"ABC","DEF","GHI"}"ABCD"Returns: 0We can trace a path for "ABC", but there''s no way to complete a path to the letter ''D''.3{"AA","AA"}"AAAA"Returns: 108We can start from any of the four locations.

在例1的find字符串的第一个字符是''A''，我们可以看到在相应的grid中，''A''在两个位置上出现，由于起点不限，所以我们搜索到的起点有2个；find的第2个字符是B，我们可以看到grid中只出现了1个B，而按照题目要求移动的话，显然只有左上角的那个A可以移动到这个B的位置。

By anchoring an imaginary spring between each data point and deformable curve or surface, the fairing model is established. Then FEM is used to solve the deformation problem of the model caused by imaginary springs and a bicubic B-spline surface patch is taken as one element. Lastly the B-spline active surface model is applied to surface reconstruction from layer data and the problem resulted from fitting for uneven cross-sectional curves can be solved.

通过在数据点与模型之间连接虚拟弹簧，建立光顺模型，并以双三次B样条曲面片作为单元，运用有限元法对模型在虚拟弹簧作用下的变形问题进行求解，得到光顺后的B样条曲面；并在此基础上，提出了一种新的基于断层数据的表面重建方法，可很好地解决不均匀截面族的曲面生成问题。
