The experimental results were followed:(1) LY402 could degrade chlordane in an aerobic environment. The percent of chlordane degradation at 1.0 mg /L was more than 94% after 4 days at 30℃. When exposed to a concentration as high as 10.0 mg/L, LY402 could still degrade 61% of chlordane. There was no obvious difference between cis-chlordane and trans-chlordane in the mixture on biotransformation rate.

实验结果表明：(1)在好氧条件下，LY402能够有效降解氯丹，对于1mg/L的顺式氯丹和反式氯丹混合物，在30℃下，经过4天的好氧降解，其总降解率接近95%，进一步将氯丹混合物的总量增加到10.0mg/L，其4天的总生物降解速率仍然能够达到64%，其中，顺式氯丹和反式氯丹的生物降解速率没有明显区别。

Propylene oxide is an important chemical intermediate. At present, the industrial production of PO includes mainly Chlorohydrin process and Halcon process.

环氧丙烷是一种重要的工业原料，目前工业上生产环氧丙烷的方法主要有两种：氯醇法和Halcon法。

The further development of conventional industrial processes of propylene oxide using the chlorohydrin route or oxirane technology is limited due to environmental pollution and its high production cost,so that the demand of exploring novel,economical and clean technologies for PO production becomes important.

环氧丙烷传统的工业生产方法如氯醇法路线或共氧化技术由于环境污染或成本较高等原因阻碍了其进一步发展，开发既清洁又经济的绿色合成技术是环氧丙烷工业今后的发展方向。

Propyleneoxide is produced with chlorohydrin method or Halcon method which gives rise toenvironmental pollution or a large amount of co-product.

是最洁净、廉价的氧源，但工业上除乙烯外，其它环氧化合物还不能通过〓直接高选择性环氧化相应的烯烃制得。

In my opinion, Cu complexes with unsaturated alcohol to form a complex compound; the nitrogenous compound introduced serves as the complex compound's stabilizing agent and reduces activation energy of reaction; TMPO serves as oxygen carrier and displays it's selective oxidation function. This new method and mechanism also demonstrates significance to other similar organic reactions.3 In the chlorohydrin reaction, NaCIO is replaced by Ca2see Chapter4.4.3.4(2 .A, this method hasn't been reported in previous literature,which exerts more buffer action to the react system, the yield increased from 52% to 88.6%; at the same time it solve the problem of poor stability and low percentage composition of NaCIO.

认为：CuD与烯醇形成络合物：含氮有机物的引入起到稳定络合物，降低活化能的作用：而TMPO则充当携氧子起传递氧的作用，并具有选择氧化功能：这种新的方法和理论对类似的反应(不饱和醇类在络合体系下选择性催化氧化为对应的醛也具有重要的指导作用。3在异戊二烯的氯醇化反应中，用次氯酸钙代替次氯酸钠见第4章4.3.4(2.A，本方法未见文献报道，使反应系统更加温和，收率由52%提高到88.6%：并解决了次氯酸钠稳定性差、有效氯含量低的实际问题，具有重要的实用意义。

Under the same conditions of illumination and the concentration of nutrition, copper chlorophyll has advantage of no-repollution, no-poison, better effect, long-time effect of restrain and so on, comparing with copper ion, and the mechanism that copper chlorophyll and copper sodium chlorophyllin have very strong influence to growth of microalga is analyzed in the theory.
