中文摘要: 2000年8月在甘肃省玛曲县,利用Bigg型混合云室进行了四个温度下的大气冰核浓度的测量,分析了冰核浓度日变化的特点,以及随天气状况、气压等要素变化的关系。通过与北京、兰州、西宁等一些地区的观测结果的比较,可以看出在人为活动较少的玛曲,自然冰核和我国北方其他地区相比,接近于西宁、西安、北京(1 963 )和大连等地的浓度值,而比甸子山及北京90年代的观测值要少。

Abstract:In August 2000, the content of ice nuclei in the atmosphere in Maqu area of Gansu Province was observed with mixing chamber. Then the feature of content′ variation in the days different, weather conditions and pressures is analyzed. By comparation with the results of Beijing , Lanzhou City,Xining City and some other regions , the content of ice nuclei in Maqu area is less than those of some other regions, such as Beijing in the 90s and Lanzhou City.Moreover, the content in Maqu area is close to the result of Beijing in 1963.
