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？

In order to produce environment-friendly new formulated gasoline to meet stricter requirement of environmental protection and to supply the data for the development of β zeolite catalyst and the design of reactor,the macrokinetics of TAME liquid-phase synthesis catalyzed by β zeolite was studied,where isoamylene was etherified with methanol.

为了生产有利于环境友好的新配方汽油，以适应环境保护的更高要求，为β沸石分子筛催化剂的开发和反应器的设计提供数据，对异戊烯和甲醇在β沸石分子筛催化剂作用下合成TAME液相醚化反应的宏观动力学进行了研究。

A series of rosin pentaerythritol ester polyoxylethylene ether with different polymerization degree of epoxy ethane were synthesized.

The effects of different of categories surfactants, the proportion of surfactant and cosurfactant , the chain lengths of alcohol and alkane, temperatures and pH values on the W/O microemulsion phase areas are systematically studied in the dissertation. SEM and laser scatting techniques are used to verify particles'sizes of W/O microemulsion. Consequently, a system TritonX-100/n-C〓H〓OH (weight ratio 1: 1)/C〓H〓/H〓O is obtained which is a stable system with relatively large W/O microemulsion phase area.

本文系统研究了表面活性剂种类、助表面活性剂的链长、表面活性剂和醇的配比、烷烃的链长以及温度、pH值等对W/O微乳液相区域的影响，并用SEM、激光光散射等对微乳液粒度进行了表征，从而获得一种稳定的、W/O微乳液区域较大的体系：壬基苯酚聚氧乙烯醚(TritonX-100)/正戊醇(质量比1：1)/环己烷/水体系。

By the bio-assay directed fractionation of the volative constituents.dimethyl disulfide,allyl methyl trisulfide,allyl methyl sulfide and diallyl disulfide were found to increase the beating rate and beating amplitude in a standard medium,but the compund 2-pentanone without sulfide did not affect either of them.

从具有生物活性的挥发性提取物中分离得到的二甲基二硫、烯丙基甲基三硫、烯丙基甲基硫醚和二烯丙基二硫对培养心肌细胞心率和振幅均有不同程度的增强作用，而不含硫的2-戊酮则没有作用。

The effect of the mixture was 98.4 to 71.5% against powdery mildew of cucumber at 10-40 mg/L. The results showed that the mixtures in 1﹕10 had obvious synergistic interaction, and it can postpone fungicide resistance.
