基于Matlab Web Server和WWW构建了空间虚拟实验室(VLSP),并简单介绍了数据分析系统。通过一个具体的电流片结构分析事例阐述了电流片结构分析模块的具体实现。应用该系统具体分析了2003年8月6日Cluster卫星观测到的重联耗散区附近的电流片结构。该系统具有良好的实用性和可扩展性,极大地方便了科研人员的研究工作。
Magnetic reconnection is a fundamental process in plasma,which is thought to play important roles both in laboratory and natural plasmas through affecting magnetic topology,heating and accelerating particles. During an event on Oct. 1st,2001,the Cluster tetrahedron circled around the magnetic reconnection region several times,and Xiao et al. first identified the null pair and found that the spectrum of the null-point oscillation shows the maximum power near the lower-hybrid frequency. In this paper we report the observation of electromagnetic and electrostatic wave enhancements near lower hybrid frequency associated with the reconnection process near the null pair. The lower hybrid waves(LHWs) with quasi-perpendicular propagation were identified and also confirmed by the power law of the spectrum of electric and magnetic fields.
