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。

When the receiving aperture is much larger than the scattering disk scale, the aperture-smooth effect is remarkable and the derived variance approximates the result given by weak-fluctuation theory for any zenith; when the receiving aperture is much smaller than the scattering disk scale, the low-pass filter effect of the scattering disk scale is dominating and weak-fluctuation theory is valid only for small zeniths.
散射盘尺度和接收孔径对到达角起伏起平滑作用，当接收孔径远大于散射盘尺度时，由于孔径平滑作用，导出的表达式在任意天顶角都可以近似为弱起伏理论给出的结果；当接收孔径小于散射盘尺度时，散射盘尺度的平滑作用明显，接收孔径的平滑作用相对较小，传统的到达角起伏理论仅在小天顶角是适用的，在大天顶角必须用新导出的方差表达式。
