摘要

本文从理论上研究了在45°-90°天顶角变化范围内，电离层超热f区热电子在海拔150 ~ 350 km范围内的升温速率。得到了计算加热速率的通用公式。在广义Hoegy理论框架下，加热速率由超热电子的流动函数及其能量损失率决定。通过直接数值模拟和双指数函数（BiEX-function）两种方法得到了超热电子流动的依赖关系。利用Shkarofsky动力学方法得到了能量损失函数的解析表达式。结果表明，所得到的关系与广泛使用的Swartz近似很好地吻合。计算结果表明，用所得公式计算的升温速率与实验数据吻合较好

Numerical Modeling of the Energy Loss Function of Superthermal Electrons in the Ionosphere Taking into Account the Features of the Source Function

The article is devoted to a theoretical study of the heating rate of thermal electrons in the superthermal F-region of the ionosphere at altitudes of 150–350 km in a wide range of zenith angle changes of 45°–90°. A universal formula for calculating the heating rate is obtained. To obtain the formula, the generalized Hoegy theory was used, within the framework of which the heating rate is determined by the flow function of superthermal electrons and their energy loss rate. The dependence of the superthermal electron flow is obtained in two ways: direct numerical simulation and using the bi-exponential function (BiEX-function). An analytical expression for the energy loss function is obtained using the Shkarofsky kinetic approach. It is demonstrated that the obtained relationship is in good agreement with the widely used Swartz approximation. It is demonstrated that the heating rate calculations using the formula obtained in the work are in good agreement with the experimental data
