摘　　要：目的通过地面模拟低氧环境,观察不同低氧环境对心理旋转能力的影响,探索低氧训练新模式。方法选择16名健康男性依次在地面、模拟海拔5000 m高空低氧环境、模拟海拔7500 m高空低氧环境下,进行心理旋转测验,正像和镜像的字母F、G、L、P、Q、R,顺时针和逆时针旋转0°、60°、120°、180°,测量指标包括错误率、反应时。结果 (1)错误率:海拔7500 m错误率(0.073±0.014)最高,海拔5000 m错误率(0.052±0.008)最低,二者比较差异具有统计学意义(P<0.05);随着旋转角度(0°、60°、120°、180°)增加,错误率依次递增(0.020±0.004、0.031±0.008、0.062±0.013、0.133±0.020),除了00和600之间没有显著性差异,其它角度之间均存在显著性差异(P<0.01)。(2)反应时:随着高度由地面、海拔5000 m、海拔7500 m的增加,反应时由(798.585±34.583)ms、(766.580±36.665)ms、(744.845±37.231)ms依次递减,地面与海拔7500 m间反应时比较差异存在统计学意义(P<0.05);与正像反应时(706.870±28.218)ms相比,镜像反应时(833.137±43.028)ms显著延长,二者比较差异具有统计学意义(P<0.01);随着旋转角度(00、600、1200、1800)增加,反应时[(692.309±32.886)ms、(710.697±32.648)ms、(782.300±35.384)ms、(894.708±42.794)ms]依次增加,两两比较均存在显著性差异(P<0.01或P<0.05)。结论低氧暴露对心理旋转能力有较大影响,可开展缺氧体验训练与心理旋转测验相结合的航空生理训练新模式。Objective To observe mental rotation ability of ground-based simulation in different low-oxygen envi- ronments and explore new hypoxia training pattern. Methods Sixty healthy males were successively performed with men- tal rotation tests （rotated erect and mirror image of letter F, G, L, P, Q and R by 0°, 60°, 120°, 180°, respectively, clockwise and anticlockwise） in ground-based simulation, simulating under high-altitude hypoxic environment about 5000 and 7500 rn. The measurements including error rate and reaction time were recorded. Results OError rate： error rate of 7500 metres was highest, and error rate of 5000 metres was lowest（0. 073 ± 0. 014, 0. 052 ± 0. 008, P〈Z0. 05）. With the increase of rotation angles （0°,60°, 120°, 180°）, the error rates were significantly increased in turn, except 0° and 60° （0. 020±0. 004, 0. 031 ±0. 008, 0. 062 ± 0. 013, 0. 133 ± 0. 020, P〈0. 01）. （2）Reaction time： with the increase of altitude （ground, 5000 m, 7500 m）, the reaction time decreased in turn. There was significantly difference between ground and 7500 m [（798. 585 ± 34. 583）, （744. 845 ± 37. 231） ms, P（0. 05]. Compared with the reaction time of normal group ,that of mirror group was significantly longer [-（706. 870 ± 28. 218）, （833. 137 ± 43. 028） ms, P（0. 01-]. With the in- crease of rotation angles（0°, 60°, 120°, 180°）, the reaction time were significantly increased in turn [-（692. 309 ± 32.886）, （710.697±32.648）, （782.300±35.384）,（894.708±42.794）ms, P〈0. 01 or P〈0.05].Conelusiun Hy- poxia exposure has a strong influence on the mental rotation ability, and aviation physiology training can carry on new pattern about hypoxia experience combining with mental rotation tests.
