目的观察垂直运动方向不同振动频率下歼击机飞行员视力变化情况,为建立该条件下歼击机飞行员运动状态视力的测试方法提供依据. 方法分别测试48名歼击机飞行员和46名健康地面受试者,在0、4、4.5、5、5.5、6、6.5、7 Hz振动频率和振动幅度10 cm条件下做持续垂直运动的视力,并进行F检验和t检验分析. 结果在振动幅度恒定的前提下,随着振动频率的增大,地面受试者和飞行员运动状态下视力都表现出下降的趋势,但在4、4.5、5、5.5、6、6.5和7 Hz频率,地面人群动态视力明显低于飞行员(f=10.20～14.90,P<0.01). 结论飞行员的动态视力具有不同于一般人群的特点,静态视力检查时不能发现这种差别,提示在飞行医学员鉴定时进行运动状态视力检查很有必要,可以作为一种评价前庭眼动反射和特殊职业人员鉴定的测试方法 .

Objective To obtain the characteristics of dynamic visual acuity (DVA) of pilot at different vertical vibration frequencies, and to provide experimental evidence for the establishment of vibration DVA test for pilots. Methods The DVA of 48 pilots and 46 subjects were measured re-spectively at 0, 4, 4.5, 5, 5.5, 6, ft. 5 and 7 Hz vertical vibration frequencies, as well as their static visual acuity. The data were analyzed by F and t test. Results In case of same amplitude main-tained the DVA was decreased with the vibration frequency increase both in pilot group and in subject group and there was significant difference in DVA between pilot group and subject group at all fre-quencies except stationarity(t=10.20～14.90, P<0.01). Conclusions Other than ground sub-jects, pilot group under vibration shows different DVA characteristics which can not be found in static visual acuity test. It suggests that it's necessary to implement a DVA test under vibration during pilot physical assessment, and it can be used as a method for evaluating and assessing vestibulo-oeular reflex of special personnel.
