不同轴向的径向加速度对科里奥利错觉的影响

目的 X、Y轴向的径向加速度对科里奥利错觉的影响。方法 分别对10名青年男性健康志愿者在GL－2000高级空间定向模拟器上，由X轴向径向加速度为 0.27Gx与0Gz时，Y轴向径向加速度为 0.27Gy或0Gy时等量的科里奥利加速度刺激（0.16cm/s^2)引起的科里奥利错觉形态、持续时间、强度进行了比较。结果 同无径向加速度作用相比，在X轴向径向加速度为0.27Gx及Y轴向径向加速度为0.27Gy时，等量的科里奥利加速度刺激引起的科里奥利错觉形态不改变，错觉持续时间明显降低（P＜0.05)，错觉强度明显增强（P＜0.05)。结论 X、Y轴向径向加速度对科里奥利错觉形态无影响，对错觉持续时间及强度均有一定影响，必须加强对径向加速度作用下的科里奥利错觉的预防与克服措施的研究。

The effect of Gx and Gy on Coriolis illusion

Objective To explore the effect of different axial(X or Y axis) radial acceleration on Coriolis illusion. Methods Ten healthy young men served as subjects. The experiments were performed in GL 2000 advanced spatial disorientation simulator. The form, duration, and intensity of Coriolis illusion induced by equated Coriolis acceleration stimulations with and without the effect of 0.27 G x or 0.27 G y were observed and compared. Results As compared with those without the effect of G x or G y, under the effect of 0.27 G x or G y, the form of Coriolis illusion remained the same, while its duration was significantly shortened( P <0.05), and its intensity significantly increased( P <0.05). Conclusion Viewing that radial and angular accelerations often occur simultaneously during maneuvers of high performance fighter, it is suggested studies about measures for preventing and overcoming Coriolis illusion under the effects of radial acceleration should be strengthened.
