DEM合成实验的优化设计

正交实验法就是一种研究多因子实验问题的重要数学方法,目前已在冶金,化工,橡胶,纺织,无线电,医药卫生等方面得到了广泛的应用。根据前人的试验总结出影响DEM合成产率的因素主要有反应时间,催化剂比例和原料配比。本文采用三因素三阶梯的正交表设计了的DEM合成实验方案,并根据该方案进行了9组实验（每组均包含2-3次平行实验）。由实验结果并根据正交实验的统计分析方法,分析了上述三因素对DEM产品含量的影响,确定了主要影响因素,并得到了最佳反应条件。

Optimal design of synthesis experiments DEM

Orthogonal experimental design is a important mathematics method to study many factors experiment.At present,it is already widely applied in many field such as chemical industry,the rubber,textile,radio,the medical and health.In according to test of forefathers,the producing rate of DEM is influenced by responsing time,proportion of catalyst and raw materials matching.The Orthogonal form of three factors-three ladders was used to design the project of composing DEM,and 9 groups of experiments have been done（per group contains 2 to 3 parallel experiment）.The result of experiments and the analytical method of the Orthogonal experimental design have been used to analysed the influence of the three factors above-mentioned,and Main factor and the best response condition have been confirmed.
