摘　　要：在典型相量图法的基础上提出基于磁路KCL、KVL导出定解约束方程的解析方法,并采用基于多元函数在约束条件下的极值分析和基于枚举法的数值分析方法对分框磁通幅值极小值存在条件进行理论分析,从而获得分框磁通的谐波成分,最后对理论计算工作进行了验证性试验。A solution based on typical .vector analysis and equations derived from KCL and KVL rule has been developed. Studies based on extreme value for multi- variables functions and enumeration method have been employed to analyze the condition of the existence of the minimum value of the magnetic flux distribution in the would core. The studies aim to get the components of the harmonic waves in the magnetic flux. Finally, the above theorecital work will be verified experimentally.
