Experiments are conducted on the effect of different types and different molecular structures of polymers on HPAM removal existed in solution or sewage. It is found out that only cationic polymer has a better removal effect of HPAM among the non-ion, amphoteric ion and hydrophobical cation polymers, especially the DMDAAC cationic polymer has an optimal result. The removal capacity to HPAM can be further improved by using appropriate molecular weight and cationic capacity and gas floatation technique.

试验研究了不同类别及分子结构的聚合物对溶液或污水中HPAM的去除效果，发现非离子、两性离子、疏水改性阳离子聚合物对HPAM无去除作用，只有阳离子聚合物去除效果较好，其中尤以DMDAAC系列阳离子聚合物效果最优，而适当的分子量和阳离子化度以及气浮技术均可以进一步提高其对HPAM的去除率。

It is proposed that the most important factor to determine the AC flashover criterion is the recovery condition, but not the reignition condition as proposed by others.

In order to understand the mechanism of pollution process around insulator under the wet condition better,based on the principle of computational fluid dynamics CFD, the numerical model,which was used to analyze three-dimensional two-phase uncompressible turbulent flow field around composite insulator in wet weather and convection-diffusion of dust particles,was established.Then,the dynamic simulation of the general approach,which was used to analyze solid dust particles' wet deposition process around composite insulator with application of CFD software-Fluent,was proposed.

为深入了解绝缘子外部在湿润条件下的积污机理，基于计算流体力学原理CFD建立了求解湿润气象条件下复合绝缘子外部三维两相粘性不可压缩湍流流场的基本控制方程组和尘埃颗粒对流扩散的基本方程，提出应用CFD软件Fluent可对复合绝缘子表面固体尘埃颗粒湿沉降过程进行动态模拟的一般方法。
