Polyethersulfone with cardo was a developed engineering thermoplastic and membrane material with high glass transition temperature,PES-C ultrafiltration membranes were prepared by phase inversion method using dimethylacetamide as solvent and oxalic acid and polyethylene glycol as additives.The membrane morphology forming and evolution could be observed by the experimental system and method.The effect of additive and polymer concentration on cast solution and the gelation kinetics of polyethersulfone with cardo asymmetric membrane were studied.

采用耐高温工程塑料——含酚酞侧基的聚芳醚砜为膜材料，草酸和聚乙二醇为添加剂， N，N -二甲基乙酰胺为溶剂，并利用改进的凝胶动力学实验装置和方法，使之能真实地再现不同膜孔结构生长及发展演化的过程，借助相关软件对图像进行处理，考察了添加剂、聚合物浓度对铸膜液凝胶速度的影响，对酚酞基聚芳醚砜非对称膜的凝胶过程的动力学进行研究。

The causes of shield tunnel defections could be divided into six branches: the segment dislocations, lining material deterioration and seepage. etc. Fault trees are also founded to illustrate each branch. 23 quantitative elements from the fault trees are selected to serve as the diagnosis indexes, all of which could be applied in engineering practice. By using the AHP method, a 3-level diagnosis index system is established. Afterwards, the procedure of setting up the quantitative judging criteria is given, as well as the relative index weight of index layer, by using the improved Analytic Hierarchy Process-multiplication scale method. At last, the values of corresponding parameters of membership functions are set, with the Cauchy distribution model.

将盾构隧道常见病害成因分为管片错位、衬砌材质劣化以及渗漏水等6个子系，对每个子系构建了病害故障树；从工程应用角度出发，从故障树中选取了23个可定量化因素作为评价指标，通过层次分析法建立了三层病害评价指标体系；对体系中单一评价指标的定量化分级方法进行简述，并给出所有指标的建议分级标准，采用改进的层次分析法－乘积标度法确定了各评判指标之间的相对权重；确定了基于Cauchy分布模型的隶属函数的关键参数。
