航海者中晕船很常见,无航海经验者60~90%患晕船病,有经验者亦可达15~60%,因此预测晕船发生的可能性和估价适应海洋情况的客观标准对海员的选择极为重要。前庭眼反射(VOR)是维持视网膜影象稳定的主要生理机制。前庭器传导的头部加速度运动可以代偿性地产生与头运动速度相同但方向相反的共轭性眼运动。这样,在头部运动时,视网膜上的影象保持不动,使我们能在运动的同时看清物体,当VOR不能适应新的情况时,即导致视网
Sea-sickness is common in sea voyagers, with 60 to 90% of nautical-no experience of seasickness and 15 to 60% of experienced experience. Therefore, the possibility of predicting seasickness and the objective criteria for assessing sea conditions is extremely high for seamen important. Vestibular reflex (VOR) is to maintain retinal image stability of the main physiological mechanism. Vestibular-mediated head acceleration movement compensates for conjugal ocular movement of the same velocity as the head but in the opposite direction. In this way, during head movement, the retinal image remains motionless so that we can see the objects while moving, and when the VOR does not adapt to the new situation,
