摘　　要：本文导出了描述汽轮发电机端部涡流场的边值问题及其与之对应的等价条件变分问题。对ＱＦＳ－３００－２型发电机的端部场作了实例计算，计算结果与实例结果相吻合。本文对影响发电视端部场的各种因素进行了详细的定性和定量分析，为大型汽轮发电机端部结构的改进提供了理论依据。The boundary value problem and the variational problem of eddy current electromagnetic field in the end region of turbogenerators are derived. The field in the end region of QFS-300-2 turbogenerators is calculated. The calculated results are identical to the measured results. The factors which affect the field are studied using quantitative method and qualitative method. This provides the basis to im prove the end structure design of large turbogenerators.
