摘　　要：目的 :探讨舰船环境因素复合作用对舰员影响的作用规律。方法 :采用综合平衡法对模拟舰船 3种物理因素复合作用的实验结果进行分析。结果 :影响听阈偏移和视觉对比敏感度函数的主因素分别是噪声和照明 ,而温湿度是影响视、听反应时和肛温的主因素 ,同时获得了 3种物理因素对舰员影响的最佳和最差量级组合。结论 :为了舰员的健康 ,对最差量级组合 ,即高噪声、低照度、高温高湿应予控制。Objective:To explore the rule of combined e ffe cts of certain shipboard physical factors on the shipcrew. Methods: Simulated experiments were made on the combined effects of such f acto rs as noise, illumination, heat and humidiy on human performance. Combined e ffec ts of principal factors were obtained by using overall balance method. Results：The principal factor that induced hearing threshold shift wa s noise, while the factor that affected the visual contrast sensitivity function value was illumination. Our experiments also indicated that heat and humidi ty we re principal factors affecting auditory and visual reaction time but rectal te mperature as well. At the same time, the best and worst combination of the thr ee p hysical factors were obtained pertaining to the combined effects on the shipcrew . Conclusion:It is suggested that the worst combinations o f intense noise, low lighting, high temperature and humidity, should be cont rolled for the health of the shipcrew.
