建立了在不变横向磁场中任意边界金属薄板的功的互等定理,并应用该定理计算了在横向磁场中两对边简支另两边固定金属薄矩形板的固有频率。%Reciprocal theorem for metal thin plates with arbitrary boundaries in constant transverse magnetic fields is established,and the theorem is applied to calculate natural frequencies of a metal thin rectangular plate with two opposite edges simply sopported and the other two edges clamped in transverse magnetic fields.
