But when the cholesterol was substituted by its oxide result, the membrane life time extended to nearly 60 hrs ;besides the diameter of the hole on which the membrane exists 、temperature、PH value cause great effects to the life time of the membrane, and the diameter was the most important element. When the diameter larger than 3mm it is almost no way to form a membrane on the hole under experiment condition. Between 1mm and 3mm it has a better result by change the prescription of the membrane. when it is 0.5mm all the membrane can last more than 40 hrs ,and the prescription like Och : phosphatidylcholine / cephalin＝4:1; 3:1; 2:1; 1:1; 2:3 need the request of the experiment basically, when cooperate with multi hole structure it is very to detect the concentration and found the model.

研究结果说明，成膜在普通胆固醇/磷脂配方下不能达到满意的结果，无论如何改变外界条件成膜始终超不过7小时，而将胆固醇换成氧化胆固醇再和磷脂按照一定配比的时候，成膜时间则大大延长，可达60h左右；另外除成膜配方，成膜孔径、温度、PH值等因素对成膜有着很重要的影响，成膜孔径对膜的影响最为关键，在3mm以上的孔径时成膜比较困难，在1－3mm适当提高成膜液浓度可以改善，孔径为0.5mm左右成膜比较稳定基本都能达到40h以上，合适的几个配方如卵/脑磷脂：氧化胆固醇＝4：1；3：1；2：1；1：1；2：3基本满足实验要求，配合一板多孔结构，可以保证单位时间的离子传输量的检测和计算。

The DSC results showed that calcium carbonate,sodium benzoate and terephthalic acid were the nucleating agents of polypropylene with high thermal stability of the nucleating effect,while the thermal stability of nucleating effect of pimelic acid,suberic acid,azelaic acid,and the two component nucleating agents suberic acid/calcium carbonate and azelaic acid/calcium carbonate were poor.

研究了碳酸钙、苯甲酸钠、对苯二甲酸和脂肪二元酸：庚二酸、辛二酸、壬二酸及其与碳酸钙组成的双组分成核剂对聚丙烯结晶成核效果的热稳定性。结果表明，高熔点物质碳酸钙、对苯二甲酸、苯甲酸钠的成核效果的热稳定性高，而脂肪二元酸的成核热稳定性低。庚二酸与碳酸钙组成的双组分成核剂的成核热稳定性高，但辛二酸、壬二酸与碳酸钙组成的双组分成核剂的成核热稳定性没有得到改善。
