摘要
文章通过已有的大气压、水汽压和气温的数据计算出杭州、拉萨两地区大气中的氧气分压和氧气分子数密度,作出1月和7月杭州地区的大气压、水汽压、气温、氧气分压、氧气分子数密度随海拔高度变化的曲线图,并对这些曲线的特点进行分析、比较与解释。对比拉萨、杭州这两地高空的相关大气数据,找出它们之间内在的联系与区别,并加以解释,发现同纬度地区高空的大气状况基本相同,尤其是大气压。根据杭州上空海拔3650m处的大气压及拉萨地表的气温推测出拉萨地表的其他大气状况,并将拉萨地表的大气与杭州上空的等高大气进行对比,发现它们总体接近。指出地形地貌对于大气的影响仅局限于地表附近,且该影响要小于季节、海拔对大气的影响。文末对文章的某些撰写思路进行了必要的解释。
Based on the data of atmospheric pressure,water vapor pressure and air temperature,the partial pressure of oxygen and molecular number density of oxygen in Hangzhou and Lhasa are calculated.The atmospheric pressure,water vapor pressure,air temperature,partial pressure of oxygen and molecular number density of oxygen vary with altitude in January and July in Hangzhou are plotted.The characteristics of these curves are analyzed,compared and explained.By comparing the relevant atmospheric data at high altitude in Lhasa and Hangzhou,we can find out the inherent links and difference between them,and explain them.It is found that the atmospheric conditions at high altitudes in the same latitude are basically the same,especially for the atmospheric pressure.According to the atmospheric pressure at 3650 m above sea level in Hangzhou and the surface temperature of Lhasa,other atmospheric conditions on the surface of Lhasa can be inferred.By comparing the surface atmosphere of Lhasa with the equialtitude atmosphere over Hangzhou,it is found that they are generally close to each other.It is pointed out that the influence of topography and geomorphology on the atmosphere is limited to the vicinity of the surface,and the effect is less than that of season and altitude.At the end of the article,some writing ideas are explained.
