First , divide the vocabulary into 5 categories (synonymy ; antonym; homophony; homomorphism; conjugate) Second, different strategies to different categories but to make the CAI visual, interesting, and systematic. The thorough strategies carried out in the experiment are as follows: Use picture-showing to differ some synonymies ; Use movie clip to learn some antonym; Use flash cartoon to create the mini-situation of homomorphism ;Use audio equipment to learn homophony; Use specific characters and design crossword to help students memorize the conjugates.

多媒体词汇教学在实践中的具体应用策略如下：近义词学习主要采用图片直观法，文本讲练法，图示辨析法，英英连线法进行实验；反义词学习主要采取下面三种形式，结合影片片段学习反义词，学生参与反义词教学，和游戏竞赛学习；形近词学习主要采取利用动画情境联想教学，利用歌曲的Flash动画学习形近词的策略；近音词、同音词学习方式主要采取利用音频手段比较学习，利用操练的形式学习近音词；同根词学习采取多变字效学习及crossword 学习的策略。

A new general kinetic equation was derived in which the effect of the removal of condensation water was taken into account completely, and was applied to the polyesterification kinetic study of AA/HPHP and AA/NPG. It was found that the reaction order of self-catalyzed polyesterification was not constant. For these polyesterifications, the reaction order was 2.5 at a low temperature, while 3.0 at a high temperature.
