摘要
目的探索新的晕机病易感性预测方法。方法采用诱发试验的方法对３１０名飞行学员进行了晕机病易感性的预测。刺激手段是阶梯式增加的Ｃｏｒｉｏｌｉｓ加速度刺激，并采用Ｇｒａｙｂｉｅｌ急性运动病症状分级标准作为反应高低的评定依据。预测结论共分Ａ、Ｂ、Ｃ、Ｄ、Ｅ和Ｆ六级。然后在检验飞行中对２３４人的实际晕机反应情况进行了观察。将此观察结果同预测检查的结论进行了对比分析。结果不同晕机病易感性预测等级的飞行学员其晕机反应程度存在显著性差异（Ｐ＜０．０１），其晕机病停飞率也不相同：晕机病易感性预测为Ａ、Ｂ两级的学员晕机病停飞率为零；Ｆ级的全部因晕机病而停飞；Ｃ、Ｄ、Ｅ级者的晕机病停飞率分别为５．３％、１５．２％和５１．６％（Ｐ＜０．０１）。结论本研究建立的飞行学员晕机病易感性预测方法及相应的评定标准。
Objective To set up a new method for predicting air sickness susceptibility. Methods Using step up growing Coriolis acceleration as the stimulation, 310 student pilots' air sickness susceptibility were graded into A, B, C, D, E and F grades according to Graybiel's grading criteria for acute motion sickness severity Then 234 student pilots' airsick response during test flight were observed. The relation between air sickness severity during test flight and grades of response to Coriolis acceleration were analysed. Results The differences of air sickness severity during test flight among subjects with different grades of response to Coriolis acceleration were significant (P<0.01) The rates of grounding in subjects with different grades of Coriolis acceleration susceptibility were also different. None of the student pilots with A and B grades was grounded, while all of the subjects with F grade were grounded. The rates of grounding in subjects with C, D, E grades were 5.3% 15.2% and 51.6% (P<0.01) respectively. Conclusion The method of step up cumulative Coriolis established in this study can be used for predicting air sickness susceptibility of student pilots.
