摘　　要：为探究管制模拟下人体空间视敏度节律特征,设计并开展了36 h睡眠剥夺状态下的管制模拟实验。首先,根据国家标准设计测绘了高精度对数视力表,以提高测量精度;其次,记录12名被试不同时间段的任务绩效和空间视敏度;最后,分析空间视敏度与管制模拟成绩的变化趋势,提出人体空间视敏度节律模型。研究结果表明:各被试管制模拟成绩与空间视敏度均值变化趋势基本一致。被试的空间视敏度周期为24小时且整体呈现出“三波峰三波谷”下降趋势,依次在7:30、15:30以及23:30达到峰值,在11:30、19:30以及3:30达到谷值,空间视敏度的节律曲线模型为c (t)=-0.00073+0.00190cos (πt/(12)-0.03095)+0.00130cos (πt/6+0.37739)+0.01029cos (πt/4+0.40371),该模型为基于视敏度的管制绩效预测提供了一种可能。To explore the rhythmic characteristics of human spatial visual acuity under regulatory simulation, a 36 hour sleep deprivation control simulation experiment was designed and conducted. Firstly, a high-precision logarithmic visual acuity chart was designed and surveyed according to national standards to improve measurement accuracy;Secondly, task performance and spatial visual acuity of 12 participants at different time periods were recorded;Finally, the trend of changes in spatial visual acuity and control simulation results was analyzed, and a human spatial visual acuity rhythm model was proposed. The research results indicate that the simulated results of each test tube system have a similar trend to the average change in spatial visual acuity.The spatial visual acuity of the participants has a period of 24 hours and shows a decreasing trend of "three peaks and three valleys", reaching its peak at 7 : 30, 15 : 30, and 23 : 30, and reaching its valley at 11 : 30, 19 : 30,and 3 : 30. The rhythm curve model of spatial visual acuity is c(t) =-0.00073 + 0.00190cos(πt/(12)-0.03095) +0.00130cos(πt/6 + 0.37739) + 0.01029cos(πt/4 + 0.40371), which provides a possibility for predicting regulatory performance based on visual acuity.
