采用电子响应的漂移动力学描述，对具有零线和强垂直引导磁场的二维无碰撞磁场重联的非线性演化进行了解析和数值研究.在固定的平行正则动量的电子分布函数的叶理，使我们能够建立一个明确的联系流体和动力学制度的碰撞重联不稳定性的平流和混合的拉格朗日不变量。
The nonlinear evolution of the two-dimensional collisionless magnetic field reconnection in a configuration with a null line and a strong perpendicular guide magnetic field is studied analytically and numerically by adopting a drift-kinetic description of the electron response. The foliation of the electron distribution function at fixed parallel canonical momentum allows us to establish a clear link between the fluid and the kinetic regimes of the collisionless reconnection instability in terms of the advection and mixing of Lagrangian invariants.
