Abstract
目的 对飞行人员夜视体验训练结果进行统计分析,研究影响该训练结果的相关因素,为进一步规范现行试用的夜视训练方案提供参考数据.方法 本研究介绍了基于T2/YSX-1型夜视生理现象体验系统现行试用的夜视生理体验训练方案,分析影响训练结果的相关因素.结果 明视力在夜视镜(night vision goggles,NVGs)调焦和旁中心训练结果分布概率中差异有统计学意义(P＜0.05);不同机种在深度觉测试中差异有统计学意义(P＜0.05);扫视与注视相比对克服夜间近视差异有统计学意义(P＜0.05);试行规范中裸眼平视和佩戴NVGs平视在深度觉测试中差异无统计学意义(P＞0.05);佩戴NVGs俯视与裸眼平视、佩戴NVGs平视测试结果比较差异均有统计学意义(P均＜0.001).结论 明视力是影响NVGs调焦和旁中心训练结果的重要因素;扫视可以有效缩短近视距离,较早地发现目标;而机种和视觉角度则是影响距离判断和立体视觉的相关因素.
Objective To provide reference data for further standardizing the current scotopic vision training pro-gram by analyzing the results of scotopic vision experience training of aircrews and studying the related factors that affect the training results.Methods This study introduced the current trial scotopic vision physiological experience training pro-gram based on T2/YSX-1 scotopic vision physiological phenomenon experience system,and analyzed the related factors affecting the training results.Results Photopic vision in the night vision goggles(NVGs)calibration and paracentral training in the probability distribution was statistically significant(P＜0.05);there was significant difference in depth perception test between different aircraft types(P＜0.05);saccade and gaze had statistical significance in overcoming scotopic myopia(P＜0.05);in the trial standard,there was no significant difference between head-up with naked eyes and head-up with NVGs in depth perception test(P＞0.05);there were statistically significant differences in the results of over-head test with NVGs between head-up test with naked eyes and head-up test with NVGs(all P＜0.001).Conclusion Photopic vision is an important factor affecting the results of NVGs focusing and paracentral training;sac-cade can effectively shorten the myopic distance and find the target earlier;the type of aircraft and the visual angle are the related factors affecting the distance judgment and stereo vision.
