The coking and deactivation process of benzene and ethylene alkylation reaction over AB-97 zeolite has been studied systematically. The results of acceleration deactivation reaction indicate that deactivation process go through three phases, high level activity stability period, activity decline period and low level activity stability period. The mechanism of this phenomenon was analyzed by the way of the experiment research of pore structure and acid quality of coked zeolite. It is concluded that reducing the strong acid active centers and crystal outer-surface active centers are benefit to improve the activity stability of zeolite.

在AB-97型分子筛催化剂上对苯/乙烯烷基化制乙苯反应体系的结焦失活历程系统实验研究，催速失活实验结果表明失活历程经历高水平活性稳定期，活性衰退期和低水平活性稳定期三个阶段，并通过对失活催化剂的孔结构及酸性质的实验研究，对这一现象进行了机理分析，认为催化剂改性研究中采用降低强酸活性位和晶粒表面活性位这两种手段都有利于改善催化剂的活性稳定性。

As far as the Fe catalytic system, the higher the Al/Fe molar ratios, the stronger Lewis acidities and the higher reactivates of carbon-aluminum bond in the cocatalysts resulted in the higher polymerization activities.

以铁配合物为主催化剂时，各种助催化剂催化乙烯聚合活性随Al／Fe比的增加而升高；助催化剂的Lewis酸性越强，其分子内碳—铝键的反应活性越高，聚合体系的聚合活性则越高。

We have no common name for a mime of Sophron or Xenarchus and a Socratic Conversation; and we should still be without one even if the imitation in the two instances were in trimeters or elegiacs or some other kind of verse--though it is the way with people to tack on 'poet' to the name of a metre, and talk of elegiac-poets and epic-poets, thinking that they call them poets not by reason of the imitative nature of their work, but indiscriminately by reason of the metre they write in.

索夫农 、森那库斯和苏格拉底式的对话采用的模仿没有一个公共的名称；三音步诗、挽歌体或其他类型的诗的模仿也没有——人们把&诗人&这一名词和格律名称结合到一起，称之为挽歌体诗人或者史诗诗人，他们被称为诗人，似乎只是因为遵守格律写作，而非他们作品的模仿本质。

The relationship between communicative competence and grammar teaching should be that of the ends and the means.
