摘　　要：11名健康男性被试分别给予相当于地面和4300米高度的氮氧混合气．记录听觉事件关联电位．用多分辨小波变换方法分析两种供氧状态下被试的事件关联电位，并对变换系数进行了统计学分析．结果表明，小波变换的细节成份对缺氧敏感，与正常供氧时相比呈显著差异．This study recorded the event-related potentials (ERP) of eleven healthy male subjects who were in the condition of acute altitude hypoxia caused by in halation of 1ow oxygen mixture. The multiresolution wavelet transform and statistics were used to analyze the ERP. The result demonstrates that the detail components are sen-sitive to the hypoxia.
