偶极子功率的源区计算
Source-region calculation of dipole power
摘要：
对速度扩展到三阶的单个电荷系统的源区域中的延迟电场的精确计算表明，系统中所有非相对论加速电荷都以拉莫尔速率发射偶极电磁能。一般来说，一些发射的偶极功率通过对系统中的其他电荷做功而被重吸收，而一些则被辐射。如果系统的净偶极矩为零，则所有发射的偶极功率都被重吸收，而没有辐射。
英文摘要：
An exact calculation of the retarded electric field in the source region of a system of individual charges, expanded to third order in velocity, shows that all nonrelativistic accelerated charges in a system emit dipole electromagnetic energy at the Larmor rate. In general, some of the emitted dipole power is reabsorbed by doing work on other charges in the system, and some is radiated. If the system has zero net dipole moment, all the emitted dipole power is reabsorbed, and none is radiated.
