发现指数函数外推法引入数据处理后大大改进了大气温度的归算结果，而对气压归算的影响却很小。
It is confirmed that exponential function extrapolation contributes much to the improvement of inverted temperature; however it does much less for pressure inversion.
本文采用两种方法来解决高温温区的外推标定问题，即基于二次曲线的导数最小二乘法和基于修正指数模型的趋势外推法。
One is differential least square method based on conic, and the other method is trend extrapolation based on modified exponential model.
