摘要
摘要:地基大功率电波加热电离层是通过地基大功率短波发射机向电离层发射无线电波，通过波-粒和波-波的相互作用将无线电波的能量注入电离层.通过这种有目的可操控的方式改变电离层电子密度和温度的分布，可以深入研究电离层中等离子体能量和物质的非线性演化过程，特别是电离层电子的非平衡态分布和加速问题.本文通过对电离层加热中几个比较重要物理过程的评述，对过去20年来我国研究****在这一研究方向上取得的重要进展进行了介绍.

Abstract:Ionospheric heating by powerful radio wave is realized through radio wave injection into ionosphere by ground-based shortwave transmitter emission. Energy of radio wave can be transferred into ionospheric plasma through wave-particle and wave-wave interaction. By utilizing this object-oriented and manipulative operation, ionospheric electron density and temperature can be artificially changed. The most important physical processes includes the nonlinear evolution of ionospheric plasma, electron non-equilibrium distribution, electron acceleration, etc. In this paper, we present the principal process of ionospheric heating and introduce the recent research progress achieved by Chinese scholars.
