Analysis of the treated aqueous solution was conducted with GC-MS,and the main intermediates during phenol degradation were isobutyric acid,malonic acid,benzoquinone,butenoic acid,oxalic acid,maleic acid,succinic acid,hydroquinone,catechol and resorcin.

利用GC-MS分析了苯酚降解主要中间产物为异丁酸、丙二酸、对苯醌、丁烯酸、乙二酸、顺丁烯二酸、丁二酸、邻苯二酚、对苯二酚及间苯二酚等，并据此推测了苯酚电催化氧化的可能反应途径。

The mass transter can be enhanced ,when we introduce sulfuric acid and cuprous oxide into this system.The model is formed to describe the transference of the martial between the four phases: gas-liquid-liquid-gas, which can explain some problems. We analyze the dead of the catalyst, and make a conclusion that the surface of the catalyst is covered with some compounds such as bluestone, which lessen the activity points of the catalyst and debase the activity.

在SO_4~(2-)／ZrO_2-La_2O_3催化的反应系统中加入稀硫酸和氧化亚铜促进了异丁烯和一氧化碳的传质、使反应得以快速，高选择性的进行，异丁烯的转化率达95％以上，特戊酸的收率达47％；讨论了g-l-l-s传质过程；对催化剂作了失活分析，催化剂失活的原因是因为反应后的催化剂表面覆盖了一层硫酸盐，使催化剂的活性中心数减少，活性降低。

D. of the catalyst increased, i. e. the acid volume of the catalyst increased, the conversion for isobutene and the selectivity for trimer increased also, while the selectivity for dimer decreased, and the selectivity for tetramer was almost unchanged.

D。增加时，即催化剂的酸量增加时，异丁烯的转化率和三聚物的选择性也增加，但二聚物的选择性降低，四聚物的选择性则几乎没有变化。

In comparison with the organic solvents as reaction medium, higher conversion was achieved the tert-ethyl valerate could be formed in the ionic liquid medium.

当反应体系中存在水时，有特戊酸生成。表明反应中2，2，4-三甲基戊烷首先发生β-断裂反应，生成叔丁基正碳离子和异丁烯。

A four-ball tester was used to evaluate the load carrying and antiwear properties of bismuth dibutyldithiocarbamate,bis-dibutyldithiocarbamates(V7723),sulfurized isobutylene,molybdenum ester non sulfur and phosphorus in a mineral oil respectively and their synergistic effects.

利用四球试验机评价了二丁基二硫代氨基甲酸铋与二丁基二硫代氨基甲酸酯(V7723)、硫化异丁烯和非硫磷钼酸酯添加剂的极压和抗磨性能，以及它们之间的极压和抗磨协同作用。

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.

交际能力和语法的关系应该是目标与途径的关系。
