| 摘 要： | 对拉萨市空气含氧量进行了研究,分析了该值的日变化、逐日变化,并结合气象因子分析了可能导致该变化的原因。结果表明:拉萨市含氧量一天内有明显的峰值和谷值;含氧量变化与相对湿度显著负相关,与温度、气压不能通过相关性检验;与海平面地区含氧量相比,拉萨市含氧量变化不大;含氧量与每立方米空气中氧气的质量没有直接关系,不能用来衡量空气中氧气的绝对含量。

| Abstract: | This paper investigated diurnal variation and daily change of the oxygen content in the air over Lhasa city, and analyzed the cause with meteorological factors.Resultsshow:1) the content has a obvious peak and valley value.2) the oxygen content has negative relation with relative humidity and it has no close relation with temperature, air pressure.3) Comparing with the content over sea-level area, the oxygen content over Lhasa city is smaller than the mentioned area.4) There is no direct relationship between oxygen content with oxygen quality per cubic meter of air, it can not be used to measure the Absolute content of oxygen in the air. |
