摘　　要：从前期参数测量数据确定预测的因子和预测对象(电磁骚扰值),并根据数据的统计特性对其分级,然后归并模糊蕴涵式语句确定模糊关系集,构造预测区间修正因子的隶属函数。在确定合理的判决原则下,代入设计参数或理论数据得到预测电磁骚扰值的方法。该方法避免了传统电磁兼容预测方法的模型求解困难性和应用局限性,算例表明该算法对汽车电子电磁兼容性设计是有帮助的。A technique of ascertaining the prediction factors and the prediction objects, e. g. the values of the electromagnetic interference （EMI）, from the early parameter measurement data was proposed. The data were classified based on their statistical character, the fuzzy relation set was ascertained from the merging of the fuzzy implication relations, and the membership functions as the correction factors of the prediction scope were constructed. The predicted values of the EMI were obtained from the designed parameters or the theoretical data under the rational judging criteria. The suggested technique can avoid the difficulties of the conventional electromagnetic compatibility （EMC） prediction method in model solution and application limitation. The computation example illustrated its usefulness in the vehicle EMC design.
