获得了轴对称脉冲星的静止无力磁层的某些精确性质。特别地，表明磁分线相对于赤道面具有77.3度的倾角。电磁场在光柱附近的分界线内具有 R(-1/2) 奇点。提出了磁层的数值模拟，它粗略地再现了这些特性。数值结果用于估计轴对称脉冲星的功率：L=(1+/-0.1)mu(2)Omega(4)/c(3)。因此，所有令人费解的脉冲星现象发生的背景磁结构现在已经有了一定的把握。
Certain exact properties of the stationary force-free magnetosphere of an axisymmetric pulsar are obtained. In particular, it is shown that a magnetic separatrix has an inclination angle of 77.3 degrees to the equatorial plane. The electromagnetic field has an R(-1/2) singularity inside the separatrix near the light cylinder. A numerical simulation of the magnetosphere which crudely reproduces these properties is presented. The numerical results are used to estimate the power of an axisymmetric pulsar: L=(1+/-0.1)mu(2)Omega(4)/c(3). Thus, the background magnetic configuration, on which all the puzzling pulsar phenomena are taking place, is now known with some confidence.
