This is due to the fact that AFP in the sample flows through the sample pad and binds the conjugate to form a complex. This complex then migrates down to the membrane and binds to the immobilized anti-AFP antibody A2 of the test line, resulting in the immobilization of the reddish conjugate.

如果样品中含有甲胎蛋白，膜上便会出现肉眼可见的微红色检测线，这是由于样品中的AFP与标记有单克隆抗体A1的免疫金结合形成复合物，复合物向膜上移动与固定在膜上的检测线单克隆抗体A2结合反应，结果在该处形成固定的微红色线条。

The result of immobilization showed that hydrophile membranes were more advantageous than hydrophobe ones to act as immobilization carrier. Crosslinking organophosphorus hydrolase by glutaraldehyde on polyethersulfone membrane is a simple and practical immobilization method. An appropriate amount of bovine serum albumin and crosslinker is necessary to get a good result of immobilization. In the biodegradation of methyl-parathion through enzyme membrane reactor, the effect of immobilized enzyme amount, flow rate of peristaltic pump, pH of the feed, and the methyl-parathion concentration on biodegradation rate was studied. It was shown that the biodegradation rate increased with immobilized enzyme amount and substrate concentration. Biodegradation rate didn't increase when the folw rate of the peristaltic pump was larger than 7 ml/min.

Both overlong or overshort bottom duration and overlong or overshort fluctuation period are unfavorable for reduction of non-diamond content. Only moderate ones have optimal effects on it.3 Compared with a smooth microwave, a fluctuating one can reduce the diamond nucleation density slightly.4 In fluctuating microwave, even if a higher CH〓 concentration chosen, diamond films with quality better than that of those deposited at a lower CH〓 concentration and in smooth microwave can be obtained.In smooth microwave, the influence of O〓 upon the diamond films＇MWPCVD was investigated. It is found that:1 In the range of lower O〓 concentration, its increase is beneficial to improvement of quality of diamond films, but in that of higher one, its increase conversely deteriorates the quality of diamond films.

在脉动微波下进行了沉积金刚石膜的研究，得到下述结果：1）采用合适的脉动微波，能使金刚石膜的沉积质量显著提高，并能使金刚石膜中的微晶石墨得到几乎完全的抑制。2）过长或过短的平底时间或脉动周期均不利于金刚石膜中非金刚石相碳含量的降低，只有适中的平底时间或脉动周期才有最佳的降低非金刚石相碳含量的效果。3）脉动微波会使金刚石的形核密度有所下降。4）脉动微波下，即使选用较高的CH〓浓度，也能得到沉积质量比在平稳微波下采用较低的CH〓浓度所制备的金刚石膜的沉积质量要明显提高的金刚石膜。

另外，选择惰性气体SF6作为微泡内气体，设计了基于两种非离子表面活性剂（Span 60和Tween 80）的包膜超声造影微泡的膜材料组成，使用声振法制备得到表面活性剂包膜的超声造影微泡；对制备过程中的声振条件进行优化，结果表明总体上振幅越大，处理时间越长，声振后溶液的总体积增加得越多，即产生的微泡量越大，并且平均粒径越小，但当声振幅度增大到90%时，随着声振时间的延长，主要增加的是大微泡的量，有效微泡的量无明显增加，因此最佳的声振条件选择为振幅90%，声振时间60s。

Results of the experimental groups: Comparison with the control groups, in 6h and 8h groups eminences of ependymal cells with cobblestone-like appearance were seen, their microvilli were further richer, and a number of microholes could be found on their base. In body part of SFO cell membrane of some ependymal cells were broken completely, their cytoplasm was no longer seen, and cell nucleus located at one side of the cell, 5-7μm in diameter and dividing lobe-like in shape.
