查询词典 have the better of

We have used GC to follow up the formation of epoxy acid and established the acidify condition; we have done series of parallel experiments to better the pivotal condensation reaction between acid and amine; In the cyclization step, we use cheap and available reagent-Lithium amide , rather than expensive LiHMDS, to proceed the reaction; and at last, we introduced green reagent-ozone to clear the phenyl group of nitrogen to avoid using heavy metal reagent-CAN. The total yield for this method is 29.8%.

通过GC监测，确定环氧酸的最佳酸化条件；对关键的酸和胺的缩合步骤，平行试验了多种条件；在环合一步，用价廉易得的氨基锂及催化量的HMDS代替昂贵的LiHMDS进行反应；氮上苯基的脱除采用臭氧，避免了重金属试剂-硝酸铈铵的使用，总收率为29.8％。

The influence of position of the substitution, strength and number of donors and acceptors, and their coplanarity and asymmetry is discussed. The results indicate that the molecules may have larger first hyperpolarizabilities when the molecules have stronger and more donors and acceptors, large asymmetry of HOMO and LUMO, better coplanarity and higher accentricity. This work attemps at finding out the relationship between the structure and the property, thus providing theoretical basis for designing nonlinear optical molecules.

The tests have Simulated the rainstorm state and the order state, and the results indicated the disposal of microorganisms-aquatic plant system is efficient. The optimization removal rate time was ascertained under the static state test, in dynamic test, comparing and analyzing the effect on removal rates of different concentration wastewater. The results showed, without aeration, the removal rate of CODCr, TN was 85.9%,75.1%, respectively, the highest removal rate of TP was 64.6%, and the concentration of DO increased steadily from 2mg/L to 7mg/L during experiment. In dynamic test, the microorganisms-aquatic plant systems have also appeared better effect on freshet, and the removal rate of TN,TP and CODCr, was 64%,69% and 81%, respectively.
