Making use of the data of 2005 elevation of Qomolangma Feng, the paper implements the detailed analysis and research of calculation principle, method and change characteristic and trend of atmosphere temperature vertical gradient and atmospheric vertical refraction.
本文根据2005年珠峰高程测量实际数据详细分析研究了大气温度垂直梯度与大气垂直折光系数的计算原则、方法及其变化特征与变化趋势,结合同以往(1975、1992年)珠峰高程测量中大气温度垂直梯度与大气垂直折光系数变化趋势的比较,得出气温垂直梯度与大气垂直折光系数均存在周日变化并给出了它们的变化趋势,提高了珠峰高程的计算精度。
