利用超灵敏的痕量气体检测方法对运动员比赛和训练前后的呼出气体进行了探测分析;采用激光光谱电流的探测的方法,设计的探测范围达到1×10-12～1×10-10 mol,且测量时间为0.5s,为运动员比赛的身体状况检测提供有效的生理参数。关于光腔增强光谱和磁致旋转光谱的研究,为特殊环境与场合下,气体浓度测量提出了新的方法。
The ultrasensitive trace gas detection method was used to detect and analyze exhaled gas of athletes before and after training. The detection range of laser spectroscopy current was 1 × 10-12 ~ 1 × 10-10 mol, And the measurement time is 0.5s, which provides effective physiological parameters for the physical condition test of athletes. On the optical cavity enhancement spectroscopy and magnetostrictive spectroscopy research, for special circumstances and occasions, the gas concentration measurement proposed a new method.
