Based on thoroughly researching and comparing among many process control devices Total Plant Solution ( TPS ) the most advanced control device is selected from many Distributed Control System ( DCS ) to accomplish the production of Epoxy Resin .

在对过程控制系统进行深入了解和详细比较的基础之上，在众多的集散控制系统中选用最先进的全厂 一体化解决方案（ TPS）来实现环氧 树脂生产过程的自动控制。

The application of TPS in the production of Epoxy Resin is researched in the article Constructing the con-figure chart of Epoxy Resin in production process . Putting forward the systemic hardware constitute and net-work structure .

研究了 TPS 系统在环氧 树脂生产中的应用，构建了TPS系统在环氧树脂生产中的配置图，提出了系统的硬件组成和网络结构。

In present paper the authors have prepared TPs products which have little caffeine by using macroporous adsorption resin to extract and purify . The product rate is 18 % - 21 % 3 the purity > 70 % . EGCG > 20 % and caffeine < 2 % .

笔者采用大孔吸附 树脂层析法 从 茶中分离，纯化 茶 多酚，制得低含咖啡碱的 茶 多酚 粗制品，得率为18%～21%，纯度≥70%，EGCG＞20%，咖啡碱＜2%。
