摘　　要：利用FOI-PERFECT程序对X箍缩进行了3D数值模拟研究,给出了X箍缩的物理图像和动力学过程,探讨了Z箍缩中出现磁重联的可能性,并指出如果双丝Z箍缩中能够出现磁重联,那么X箍缩是更有利于磁重联出现的位形,并且,X箍缩中出现多重X射线暴的一个可能原因是z轴上多个位置出现磁重联。3Dsimulations of X-pinch are performed with FOI-PERFECT which is a 3D Rad-MHD program specifically developed for Z-pinch simulations.The physical picture and dynamic processes of X-pinch are given out.The possibility of magnetic reconnection occurring in Z-pinch is discussed.We point out that if the magnetic reconnection can occur in parallel two-wires Zpinch,then the X-pinch is a more conducive configuration to magnetic reconnection,and the magnetic reconnection occurring in multiple z-axial locations is a possible reason for the multiple X-ray bursts appearing in X-pinch.
