Be based on） The film is based on the novel by Sinclair Lewis.

该影片是根据辛克莱-刘易斯的小说改编的。

The results showed that hydrogen peroxide, silanols species and TiO〓 didn't have solvolysis activity of propylene oxide. While framework Al, coordinatively unsaturated Ti〓 ions as Lewis acid sites in the framework, Ti-OH and the five member ring active titanium species formed by TS-1, hydrogen peroxide and solvent can catalyze the solvolysis of propylene oxide.

研究结果表明：原料双氧水和TS-1沸石上的SiOH和TiO〓对环氧丙烷溶剂解反应无催化活性；而下列物种对环氧丙烷溶剂解反应具有催化活性：TS-1中的骨架铝，沸石骨架中配位不饱和的Ti〓形成的L酸中心，TS-1水解产生的钛羟基和由TS-1，双氧水和溶剂相互作用所生成的五元环中间活性钛物种。

Being combining with products distribution in styrene oxidation, we propose the styrene epoxidation carry out with Ti metallacyclo intermediates, And at the same time Ti-ZSM-5 have properties both catalytic epoxidation and acid-catalysis, namely the skeletal Ti can catalyze styrene epoxidation to styrene oxide and the skeletal Ti and Al can provide Lewis acid site to cause the rearrangement of styrene oxide to phenylacetaldehyde rapidly, the solvolysis to glycols and the cleavage of C=C double bond. Ti-ZSM-5 can also provide Bronsted acid site simultaneously, which is also catalytic center for the solvolysis to glycols.

同时结合Ti-ZSM-5催化选择性氧化苯乙烯反应的产物分布结果，提出苯乙烯环氧化反应可能是通过金属有机环机理进行；Ti-ZSM-5同时具有催化环氧化和酸催化两种功能，其骨架钛可催化苯乙烯环氧化生成环氧苯乙烷，而骨架钛和骨架铝等可提供Lewis酸位使环氧苯乙烷迅速发生重排生成苯乙醛从而使其成为反应的主要产物，同时还可发生加成以及碳碳键的裂解等副反应：Ti-ZSM-5也提供Bronsted酸位，它也是生成加成产物的活性中心。

Now as the Sonics head down the stretch of the season, Lewis is more confident, more comfortable that he's found his place.

尽管是在第二轮但是超音速还是给了刘易斯一个两年的合同，而这将是刘易斯成长真正NBA球员的两年。

"I think that will be moved upward and our hope is that we will be able to accommodate the features so they don't have a stack-up," Lewis told Reuters.

Lewis告诉路透"我想能提前装完，这样就不会让影片都堆在一起等待播出"

The results show that the metal stannate combined with Mg2 can be used as a highly effective flame retardant for flexible PVC, and it can be seen that the Mg2 enhances the flame retardant properties of the samples through the endothermic dehydration, the stannate may act in both the condensed and vapor phases, but mainly in the condensed phase as a Lewis acid.

结果表明：锡酸盐和Mg2复合使用能明显提高对软PVC的阻燃效率，Mg2主要通过脱水吸热作用使材料的阻燃性能提高，而锡酸盐可分别在凝聚相和气和起作用，但主要为凝聚相Lewis酸催化机理。

"CNN"-- Bank of America CEO and Chairman Kenneth Lewis has been issued a subpoena by the New York State Attorney General's Office, which is investigating whether the bank violated state law by withholding information from investors, a source familiar with the investigation told CNN.

"有线新闻网"--美国银行CEO和主席Kenneth·刘易斯被纽约州总检察长办公室已经发起传唤，调查银行是否通过从投资者那儿拒绝给于信息违反州法律，一名熟悉调查内情的消息人士告诉有线新闻网。

And Lewis method is used in the calculation of responses, because it is simple one, and then the statics of vessel swing are calculated.
