标题： Initial accelerations of pulsars caused by electromagnetic kicks

摘要： 基于能量考虑的半定性论证表明，观测到的脉冲星高速度的物理起源是电磁性质的。 指出，半径为10公里、质量为$1.4 M_\odot$的脉冲星的初始加速度$a$可以通过关系式$a\sim k^{-1}vB^{-2/3},$估算，其中$v$是脉冲星的速度，$B$是其磁场，$k\approx10^{-17}$G$^{-2/3}$s。对99个脉冲星样本（年龄为$\leq 10^{6}$年）的分析得出结论，脉冲星出生时的初始加速度约为$10^{13}$g。 显示英文摘要

摘要： A semiquantitative argument based on energy considerations suggests that the physical origin of the observed high velocity of pulsars is of electromagnetic nature. It is pointed out that the initial acceleration $a$ of pulsars of radius 10 km and mass $1.4 M_\odot$ can be estimated by the relation $a\sim k^{-1}vB^{-2/3},$ where $v$ is the velocity of the pulsar, $B$ its magnetic field and $k\approx10^{-17}$G$^{-2/3}$s. An analysis of a sample of 99 pulsars (with ages $\leq 10^{6}$yr) leads to the conclusion that the initial acceleration of pulsars at birth is of the order of $10^{13}$g.
