查询词典 whereas

Liquid-phase epoxidation of allyl chloride with hydrogen peroxide was carried out over Ti-MWW, a novel titanosilicate with the MWW structure, to synthesize epichiorohydrin selectively and effectively. Ti-MWW proved to be superior to the conventional TS-1 catalyst in both catalytic activity and product selectivity. Ti-MWW prefers aprotic solvents of acetone and acetonitrile, both of which can restrain the solvolysis of epichiorohydrin, whereas TS-1 favors a protic solvent of methanol.

研究了具有MWW结构的新一代钛硅分子筛Ti-MWW催化剂对烯丙基氯液相环氧化高效合成环氧氯丙烷的催化性能结果表明，Ti-MWW的催化活性以及产物选择性均优于传统的钛硅分子筛TS-1，对于Ti-MWW，合适的溶剂为非质子性溶剂丙酮和乙腈，在该溶剂中环氧化物不易发生溶剂化开环反应；而对于TS-1，合适的溶剂是质子性溶剂甲醇，但甲醇可导致醇醚副产物的生成。

This is only a sophism founded on this, that it is of no importance to the human race to believe that a certain man exists, whereas it is extremely useful for them to believe the existence of a God.

而如果你作为个人开始质疑，你会发现在这个质疑中你会创造冲突，而从这些冲突中，你会理解-而不是仅仅接受一个新的体系，新的体系仅仅是另一种安眠药，它让你睡着，把你变成另一架机器。

It is when we are in this state that a literart thought springs to mind; that silence is a ray of sunshine whilst the word is mist; that silence is certainty whereas the word is doubt, and that silence is gold and the sord silver.

As soon, however, as a spoken part came in, nature herself found the appropriate metre.
