| 摘 要： | 一、引言 等离子体诊断中的低频涨落,包含了反映带电粒子随机运动和集体运动(如等离子体波、不稳定性过程)的信息。前者的信号呈“噪声”状态,后者则有一定规律。对涨落信号作相关分析,可从涨落信号的“噪声”背景中提取有规信号,并识别出不同来源的涨落信号

| Abstract: | Our study concerning the application of correlation analysis to identify waves and instabilities in plasma is presented. First,the principle of correlation analysis and its application to diagnose plasma fluctuation signals are given. Then, the data acqusition system, application program and calibration method are described. Finally, experimental results from a mirror device are given. |
