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。

In the one half part, according to the strontium nature, thermodynamic calculation of correlative reaction and the principle of the vacuum aluminothermy reduction process, with the laboratory findings of preparation strontium by vacuum aluminothermy reduction compared and analyzed in different parameter conditions, a variety of factors which effect the decomposition rate of SrCO_3 and the percent reduction of strontia are gotten out. The factors include that the decomposition rate of SrCO_3 is influenced by different addition and pressure. They also include that the percent reduction of strontia is influenced by excess coefficient of reducing agent aluminium powder, the particle size of raw material or reducing agent, the pressure of barbecuing, temperature and reduction time. According to those, we can draw the conclusion as follows:(1) Decomposition temperature of SrCO_3 is decreased by adding carbon and alumina in different degree.(2) With quantitative carbon added under the vacuum condition, the decomposition temperature of SrCO_3 is decreased obviously, which can fall 150℃ compared with atmospheric pressure.(3) In keeping 1150℃ of 2.5h, under the 5Pa vacuum condition, the decomposition rate of SrCO_3 nearly keeps in 99% steadily.

在前半部分的真空铝热还原法中，根据锶的性质、相关反应的热力学计算及真空铝热还原法原理，通过对不同参数条件下的真空铝热还原法生产金属锶的实验结果的分析比较，得出了影响SrCO_3的分解率和氧化锶的还原率的种种因素，具体因素包括不同添加剂、不同气压对SrCO_3分解率的影响，还原剂铝粉的过量系数、原料与还原剂的粒度、制团压力、温度和还原时间等对氧化锶还原率的影响，得出具体结论如下：(1)添加碳和Al_2O_3能不同程度的降低SrCO_3的分解温度；(2)真空条件下加入一定量的碳可显著降低SrCO_3的分解温度，比之常压下可降低150℃之多；(3)在1150℃恒温2.5h、真空度达到5Pa的条件下，SrCO_3的分解率几乎保持稳定在99％；(4)氧化锶的还原率随还原剂过量系数的增大而增大，但是趋势越来越小，当过量系数超过25％后，氧化锶的还原率几乎不再增加；(5)氧化锶的还原率随原料与还原剂的粒度的变细而增加；(6)氧化锶的还原率随制团压力的增加而增加，但超过一定值后，氧化锶的还原率反而会下降；(7)氧化锶的还原率随还原温度的升高而增加；(8)氧化锶的还原率随还原时间延长而增加，在本实验条件下，超过2.5h趋于稳定。
