根据经典的单粒子运动方程和加速电子产生辐射的规律，计算得到了静态均匀正交场 E0×B0飘移电子时产生自发辐射的谱函数．结果对具有任意速度量值的电子均适用．作为特殊 情况，讨论了非相对论(γ0=1)和强相对论(γ0》1)电子注入时自发辐射情况．
The angular spectrum of spontaneous radiation from crossed electric and magnetic field E0 × B0 drifting electrons is derived on the basis of the classical single-particle motion equations and the radiative law of the electron with accelerated motion. The result is applicable to those cases of the nonrelativistic and the relativistic electron incidence. The spontaneous radiation for the energy factor γ0 = 1 and γ0 》1 is discussed particularly.
