航空管制作业人员神经精神紧张影响的调查研究

EFFECTS ON NEURO-PSYCHENTONIA IN AIR TRAFFIC CONTROLLERS

对航空管制作业人员的神经精神紧张状况进行了调查。结果表明：作业人员工后主观疲劳感觉明显增强；闪光融合频率和明视持久度降低；神经行为功能下降；尿中肾上限素、去甲肾上腺素和１７－羟皮质醇含量升高。以上提示航空管制作业紧张程度较高，长时间的精神紧张可使作业人员产生精神疲劳。

Neuro-psychentonia state of 11 male air traffic controllers(ATCs) was investigated.The results indicated that after a working session the ACTs' subjective feeling of fatigue obviously strengthened, critical flicker frequency and watching lasting time decreased ’function of neurobehaviour lowered,and urinary excretion of catecholamine and cortisol increased.All above implied a high degree of intensity for air traffic control work.and a long time working session might cause obvious mental fatigue in ATCs.
