It is synthesized that the principle observational features of solar surges, especially the magnetic features within the active region of surges. Using the plasma dynamical pinch theory and Petschek's mechanism, we present a possible mechanism of solar surges, namelya impulsive magnetic flux emergence in the active region--the periodical dynamical pinchof the plasma--the fast reconnection of the magnetic force lines--the ejection of surgeplasma. This mechanism successfully explains the periodicity of the surge ejection as well as the other main physical properties of solar surges.

In the present paper we deal with the axisyrnmetric problem of steady-state global magnetospherie configuration of a neutron star in cylindrical coordinates. It is assumed that the magnetic axis is parallel to the rotation axis. The gravity, inertial force and particle collisions are neglected. After a nonlinear relation connecting the toroidal component of magnetic field with the magnetic flux function is reasonably chosen, the numerical approach gives the solution of the magneto-hydrodynamaical nonlinear equations. The magnetosphere consists of the corotation region described by a linear equation and the wind region described by a nonlinear equation. The boundary face interlacing with both zones should be matched and is determi-ned by iterative calculation. And then, the values of Ψ and a series of electrical and magnetic parameters are obtained. The solutions are determined first in the light velocity cylinder, then, extended to the region outside the light velocity cylinder, and the results of both regions give the global solution of magnetospheric configuration for a neutron star. The solutions show that magnetospherie configuration of a neutron star is complex. The magnetospherie features in both regions are quite different. The magnetic force lines are closed in the corotation region, the magnetic force lines and charges are corotation with the neutron star. However, the magnetic force lines are open in the wind region. The electrons flow out from the region between the magnetic axis and the critical magnetic force line. The protons flow out from the ring region between the critical magnetic force line and the boundary of the corotation region. Eventually those positive and negative charged particles contribute steady state flows of equal magnitude. The magnetospherie characters in different regions are also discussed.
