摘　　要：介绍了支持向量机基本理论,首次将正交设计和SVM建模相结合用于含聚油泥分离剂的优化实验,通过网格寻优对算法参数进行优化后,所建立的回归模型即能够找到理论上的全局最优点,也可直观的表现因素之间的交互作用,在同等情况下,降低了正交设计的实验次数,优化效果明显,效率提高,是一种可行、有效的优化方法。得到的最高原油回收率为92.70%,对应复配分离剂的质量分数比为YH:YC:YE=1%:1.94%:2.76%;最低油中固含量为16.69%,对应复配分离剂的质量分数比为YH:YC:YE=1.16%:2%:2.04%。The basic theory of SVM was introduced in the thesis. Orthogonal Design was first combined with SVM modelling, and used to the experiments in optimizing separation agents of Polymer sludge. By optimizing the Algorithm parameters through gird search, the regression modelling could be found out optimal point on theory, but also revealed the interaction of different inspects. Under the same situations, it decreased the times of experiments, which proved to be a feasible and effective optimizing method as highly effective and efficiency. The highest crude oil recycling rate was 92.70 % when the mass fraction ratio of mixed separation agents was YH ：YC ： YE=1% ： 1.94 % ：2.76 %; while the lowest solid content in oil was 16.69 % when the mass fraction ratio of mixed separation agents was YH： YC： YE=1.16 % ： 2 % ： 2.04 %.
