人们认为，重联是导致大量空间和天体物理物体中等离子体加速的原因。重联的发生通常与电流片平衡的不稳定性有关。平衡电流片（Harris平衡）的解析自洽模型是已知的非相对论等离子体和相对论等离子体的一些特殊情况。本文给出了非相对论和相对论无碰撞等离子体中广义Harris平衡的描述。分析了磁场的可能形状。
Reconnection is believed to be responsible for plasma acceleration in a large number of space and astrophysical objects. Onset of reconnection is usually related to instabilities of current sheet equilibria. Analytical self-consistent models of an equilibrium current sheet (Harris equilibrium) are known for non-relativistic plasmas and some special cases of relativistic plasmas. We develop a description of generalized Harris equilbria in collisionless plasmas, non-relativistic and relativistic as well. Possible shapes of the magnetic eld are analyzed.
