许多足月前胎膜早破的发生是由于亚临床感染造成羊膜特发性改变引起的，其它引起胎膜早破的因素还包括羊水过多，宫颈内口松弛和羊膜腔穿刺术。

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.

然后，研究固定化酶降解甲基对硫磷，从不同材料的膜载体固定有机磷水解酶的比较中，发现亲水膜比疏水膜适合作固定化酶载体；在此基础上，将有机磷水解酶固定在聚醚砜微滤膜上，并制成酶膜生物反应器，用于降解甲基对硫磷；戊二醛化学交联法固定时，酶液与10%牛血清白蛋白溶液的比例在3：1~2：1，与交联剂的比例在7：2~7：4范围内，固定化效果较好，并发现牛血清白蛋白和膜载体有降低酶活损失的作用；将固定化的酶膜装于酶膜反应器降解甲基对硫磷，实验结果表明：反应器的降解速率与固定化酶量呈正比，也随底物浓度的增加而加快，当流速低时，降解速率随流速增大而加快，到7ml/min以上时，降解速率不随流速脑黾佣洌到獾淖畹团ǘ任？

Most of the commercialized hollow fiber membranes are hydrophobic and need to be pre-treated by ethanol before use.

已有的TIPS法制备的商品化中空纤维大多数是疏水的，在使用前必须进行亲水化处理。

This article is to make use of the monolayer membranes and liposome to study that interaction of hypericin with model membrane to understand the influence of hypericin on the biomembrane.

本文是利用分子单层膜与微脂质粒系统探讨金丝桃素与拟生物膜之间的交互作用，来了解金丝桃素对生物膜的影响。

我们在分子单层膜中发现金丝桃素必须要有胆固醇才能稳定处於单层膜上，而且至少要三个胆固醇分子才能支撑一个金丝桃素分子。

As protein substances embed or impenetrate in membranes, a hydrophilic passage is formed in the three dimensional structure of protein, called ion-channel.

细胞膜上有蛋白质性质的物质嵌在膜上，或者贯穿细胞膜，从而在蛋白质三维结构内部形成一个亲水性通道，称作离子通道。

Ambient salinity and dietary protein level only had significant interaction on the body ash content, while no significant interaction effects were observed in other parameters. Tubules of shrimp fed with CP30 and CP40 had the normal structure, though CP40 increased the number of R cells. Tubules of shrimps fed with CP20 had relatively fewer R cells and arranged incompactly. And the basal membranes of partial tubules were in disrepair. While tubules of shrimps fed with CP50 compactly arranged with much ambiguous materials in B cells.
