沈阳至大连区间397km。乘务员实行轮乘制。选正、副司机各6名,在他们分别担当白班和夜班快车牵引任务时,进行疲劳测验。指标有视—运动反应时,寻找黑红数字时间,两位数表效率,闪光融合频率,脑电信号功率谱和疲劳主观症状询问。夜班乘务后,视—运动反应时延长,寻找黑红数字时间增加,两位数表效率下降;白班乘务后脑电信号α_1/θ比值减少,以及闪光融合频率在白班和夜班乘务后均有降低,这些都反应乘务后呈现一定的精神疲劳现象。
Shenyang to Dalian interval 397km. Flight attendant implementation of rotation system. Selected positive and deputy drivers of the six, respectively, when they were on duty and night shift train towing task, the fatigue test. Indicators are visual - motor response, looking for black and red digital time, double-digit table efficiency, flash fusion frequency, EEG power spectrum and fatigue subjective symptoms query. After night shifts, the visual-motor reaction time prolonged, the time for finding black and red numbers increased, the efficiency decreased on the two-digit table; the ratio of α_1 / θ decreased after day shift and the frequency of flash fusion decreased after day shift and night shift, These reflect the crew after a certain degree of mental fatigue phenomenon.
