1.The principle of PVC modified by MBS resin and the properties of SBR latexes reeded were briefly introduced.

1.本文简介绍了MBS树脂改性PVC的原理及对所原料丁苯胶乳特性的求。

2.The constructed solving process is to establish a general SBR model firstly, then to derive the suboptimum solution by trial and error method with the help of simulation tools.

2.所构造的解法是首通的序批式反应器模型;然后借助仿真工具试差求取次优解。
