为观察急性中度缺氧对人计算能力的影响，利用低压舱模拟３００ｍ（对照）、３６００ｍ、４４００ｍ、５０００ｍ高度的缺氧暴露，考察１６名健康男性青年的连续计算、系列加减及心算测验综合绩效的变化。结果显示，３６００ｍ缺氧暴露１ｈ，连续计算测验的错误率增加、系列加减运算的反应时延长、综合绩效下降，均达到显著水平（Ｐ＜０．０５）。４４００ｍ缺氧暴露各项测验的绩效均显著下降（Ｐ＜０．０５）。５０００ｍ暴露时各项测验的绩效进一步降低（Ｐ＜０．０１）。提示：急性中度缺氧１ｈ对人的计算能力有一定影响，且随高度的增加而加重 In order to observe the effect of acute moderate hypoxia on human computational ability, the hypoxia chamber was used to simulate the hypoxia exposure of 300m (control), 3600m, 4400m and 5000m altitude to investigate the continuous calculation, series addition and subtraction and cardiological test of 16 healthy male youth Changes in overall performance. The results showed that at 3600m hypoxia exposure for 1h, the error rate of continuous calculation increased, the response time of series addition and subtraction increased, and the comprehensive performance decreased, reaching significant level (P <0.05). The performance of 4400m hypoxia exposure test decreased significantly (P <0.05). The performance of each test at 5000m exposure was further reduced (P <0.01). Tip: acute moderate hypoxia 1h on the human computing ability to some extent, and increased with the increase of height
