Effects of trace levels of nitrous oxide on psychomotor performance.
研究了24名男性志愿者在暴露于50ppm一氧化二氮4小时后，其精神运动测试表现未出现统计显著变化。
Twenty-four male student volunteers were exposed to 50 ppm of nitrous oxide or air in an exposure chamber for 4 h in two experimental sessions. The subjects completed a battery of psychomotor tests during the final 40 min of the exposure sessions. Nitrous oxide, at this low concentration, did not produce any statistically significant changes in performance.
