摘　　要：目的：探讨脑电活动在飞行员选拔与淘汰中的参考价值。方法：动态跟踪30名飞行（学）员（年龄18～20岁，平均飞行时间265h）从入学至航校，最后进入飞行部队服役期间的3个阶段的脑电图（EEG）变化特征，并与飞行训练成绩进行相关分析。结果：①在第3阶段，δ频段功率下降（F=18．39，P=0．00），α频段功率中的α1功率增加（F=18．59，P=0．00），而α2功率减小（F=7．15，P=0．04），与第1阶段比较，差异均有显著意义。θ、β频段功率在3个阶段比较，差异无显著意义；②EEG α波波幅呈逐年下降趋势变化，但左右脑变化无显著差异；③在第2、3阶段，左右脑的α波幅差显著减小，频率差无显著差异；④随着训练成绩的逐年提高，枕部α波（主要为a。）随年份的增加呈枕部向顶部分布的趋势变化。结论：EEG监测是评价飞行员脑功能的敏感方法。Objective：To provide the evidence of cerebral funtion for selecting and superseding pilats. Methods：The characters of in EEG of 30 pilot trainees（aged from 18-20 years old）were observed dynamically in 3 stages of learning, training and air force service. The correlation between the records of flying training scores and EEG of the trainees were analyzed. Results： In the 3rd stage of air force service, EEG power in δ frequency band decreased（F= 18.39 ,P=0.00） ; The increment of EEG power in α1 frequency band（F= 18.59, P = 0.00） and decrement of EEG power in α2 frequency band （F = 7. 15, P = 0.04）were observed. During the 3 stages, there were no significant changes in θ or β frequency band, the EEG amplitude in α frequency band decreased but there were no significant change in the right or left hemisphere. In the courses of training and air force service, the deviation of amplitude in α frequency band between the right or left hemisphere decreased but that of frequency in α frequency band had no difference. The increment of EEG power in αl frequency band changed as the following records of flying training. Conclusion： Diagnosis of EEG is a useful device for the evaluation of pilots＇ cerebral function.
