摘　　要：　当载流圆环和无限长螺线管所通的电流为低频时谐载流时必将激发感生电场,文章利用 ×E k=- B t求解载流圆环和无限长螺线管的感生电场,通过理论分析获得低频时谐载流圆环和无限长螺线管全空间感生电场的表达式。The time-harmonic-curren-carrying annulus and the infinite solenoid will produce the induced electric field. In this paper, using the formula ×E_k=-Bt, the formutation of the induced electric field of low frequency time-harmonic-curren-carrying annulus and the infinite solenoid is derived, and some discussions are also given.

关 键 词：低频时谐电流 圆环 螺线管 感生电场
