结合粒子数守恒和能量动量守恒方程以及麦克斯韦场方程，研究了电子、正电子对在外场中产生后随场的相干振荡和漂移。从振荡偶的电流出发，我们得到了电磁偶极辐射的能谱。这种狭窄的光谱是如此奇特，以至于对这种辐射的检测可以识别强激光场中的电子对产生和振荡。我们还从振荡对和振荡场的能量动量张量得到了引力四极辐射的能谱。因此，我们在强激光场迅速发展的基础上讨论引力波的产生。
Integrating equations of particle-number and energy-momentum conservation and Maxwell field equations, we study the oscillation and drift of electron and positron pairs coherently with fields after these pairs are produced in external electromagnetic fields. From the electric current of oscillating pairs, we obtain the energy spectrum of electromagnetic dipole radiation. This narrow spectrum is so peculiar that the detection of such radiation can identify pair production and oscillation in strong laser fields. We also obtain the energy spectrum of gravitational quadrapole radiation from the energy-momentum tensor of oscillating pairs and fields. Thus, we discuss the generation of gravitational waves on the basis of the rapid development of strong laser fields.
