调查攀钢女行车１９３名，平均年龄２７．８岁、工龄８．８年。驾驶室内主要职业有害因素为不良气象条件、噪声、振动、ＣＯ和粉尘。结果表明，女行车工远视力、立体视觉和视觉调节功能处于良好状态，能胜任本职工作，视疲劳指标中，视觉运动反应时、阅字数和脑力工作能力指数均明显较对照组差；班前班后自身对照比较，工作日后的集体近点距离、视觉运动反应时、错误率等均显著较班前差，表明产生疲劳。认为视觉运动反应时指标对判断女行车工机体疲劳的意义更大。
Survey 193 women Panzhihua vehicles, the average age of 27.8 years, length of service 8.8 years. The main occupational hazards in the cab are bad weather conditions, noise, vibration, CO and dust. The results showed that female drivers had good visual acuity, stereoscopic vision and visual adjustment in a good condition and were able to perform their own tasks. In visual fatigue, visual readings and mental work ability index were significantly lower than those in control group After class comparison, the collective near distance after working day, visual motor response, error rate, etc. were significantly worse than before class, indicating fatigue. It is considered that the index of visual motor response is more meaningful to judge the fatigue of female driver’s body.
