聚氯乙烯

Step procedure. Firstly, glycidyl rnethacrylate was photo梘rafted onto the surface of PVC without degassing. An activated surface with active epoxy groups was formed. The grafted polymer can also act as the spacer between heparin and PVC; Secondly, heparin is attached to the grafted surface through its functional groups reacted with the epoxy groups.

第一步，通过紫外光接枝反应将甲基丙烯酸缩水甘油酯接枝到PVC材料表面，接枝链作为肝素和聚氯乙烯材料之间连接的间隔基，同时也得到了带有环氧基团的反应性表面；第二步，通过肝素分子所带功能基团与PVC材料接枝表面上的环氧基之间的反应将肝素共价键合到PVC材料表面。

Then, basing on the practical problems of the studying area-the thickness of aquifer is little, the capability of depositing water is finite, the Quaternary loose stratum directly superimposes the bedrock strong breeze girdle, the writer thinks it is difficult to answer for the water use of the polyvinyl chloride project by the centralized tube well pumping.

根据研究区含水层厚度小、储水能力差，第四系松散层直接叠加在基岩强风化层之上的具体特点，认为管井集中开采难以满足聚氯乙烯工程的需水量要求，采用集水廊道最大限度地激发河流对地下水的补给，是在这一地区获得较大开采量的有效方式。
