拉萨市近49年低层大气中氧气含量的变化特征分析
Analysis of variation characteristics of oxygen content in Lhasa for recent 49 years
摘要
Abstract
People who enter the plateau has been also influenced by the hypoxia to some extent,oxygen plays an absolutely vital role in the global biochemical cycle.Based on the meteorological observation data from 1970 to 2018 in Lhasa,it was supposed that the air in the troposphere was dry and the molecules were in equilibrium.According to the density of oxygen molecules and the oxygen tension,using the equation of state for an ideal gas,the daily mean oxygen content was calculated.The Fourier analysis was needed for fitting the distribution curve.The results showed that there may the seasonal changes for the oxygen content in Lhasa,the oxygen content was greatly affected by the temperature,followed by the vapor pressure, much the same as the atmospheric temperature in the periodical distribution.Perhaps this helps explain the oxygen content is significantly lower in summer than in winter.It was concluded that oxygen content would decrease gradually by analyzing the changing trend of oxygen content.In addition,based on the mathematical model,this paper also made a simple discussion of the variation trend of oxygen content in Lhasa in the关键词
