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。

Take the method of "subarea" and "conjunction" to segment the whole request model to three parts. Making use of boundary continuousness between medium and lining structure at stress and displacement, construct a wave function that can satisfy the stress boundary condition at horizontal surface by the scattering of SH-waves in circular part. And then, availing of the wave function, conjoin the circular part into the semi-circular hollow space at common boundary. The problem can be reduced to solve the question that can only meet the condition of "conjunction". Finally, the solution of the problem can be summarized to a series of algebraic equations and solved numerically by truncating the finite terms of the infinite algebraic equations.

The following points are emphasized:The operation models of adiabatic and diabatic distillation have been set up and the operation block, thermodynamics model and mathematical model in the simulation have been determined as well;(2)Based on the simulation and exergy analysis with Aspen Plus program, shortcut distillation design—DSTWU model and rigorous distillation design—RADFRAC model, the author has determined the heat duty, exergy losses and the distribution of exergy losses along the adiabatic column, which will help the simulation and optimization of the diabatic distillation;(3)Diabatic distillation under various operation conditions has been simulated by using energy balance method and exergy analysis;(4)How the different mixture and the various degree of separation, number of trays and feed location influence exergy saving in diabatic distillation have also been discussed;(5)On the basis of the total exergy losses along the column, different schema of the heat transfer distribution along the column have been compared and analyzed;they can be classified in three categories: heat duty equipartition approach, empirical approach, separation degree matching approach. In conclusion, different heat transfer distribution along the column will have effect on total exergy losses. In particular, most satisfactory results have been obtained by using separation degree matching approach. In order to diminish the exergy losses, heat transfer distribution should meet the needs of the request of separation degree.And on this premise, the author makes his suggestion in increasing the proportion of heat supplied to the tray with minimum exergy losses and decreasing the proportion of heat supplied to the tray with the maximum exergy losses.
