前言 与其它感觉形态相比,视力受加速度的影响最重。视力降低、周边光感丧失和黑视是研究+Gz增加引起的血管负荷的最常用的行为测量方法。这些测量是粗糙的。它们本身不能判定与加速度有关的心血管失调引起的视功能变化。选择高效扫视形式和高效处理视觉信息的能力显然是判定扫视效能重要的决定因素。平稳跟踪系统的功能是产生平稳眼动以保持 Preface Compared with other sensory modalities, visual acuity is most affected by acceleration. Reduced vision, loss of peripheral light and dark eyes are the most commonly used behavioral measures to study the increased vascular load caused by + Gz. These measurements are rough. They can not by themselves determine the change in visual function due to acceleration-related cardiovascular disorders. The ability to choose efficient scanning patterns and efficiently process visual information is clearly the decisive factor in determining the effectiveness of scanning. The function of a smooth tracking system is to produce a smooth eye movement to maintain
