电离层S_q发电机理论的研究和数值模拟

本文回顾了近百年来（１８８９－１９９０）电离层发电机理论中Ｓｑ电流体系的研究进展，分别阐述了Ｓｑ电流体系的研究意义、获得Ｓｑ等效电流体系的正演和反演方法、给出了主要代表学者的研究成果及方法，并对Ｓｑ发电机理论存在的问题和需要进一步研究的课题进行了讨论，可以看出Ｓｑ等效电流体系研究虽然取得了很大进展，二维理论也在日渐完善，但三维发电机研究无论在理论上和计算方法上都还有改进的余地，如何最大程度上合理地解释Ｓｑ的变化规律，并与磁层物理和大气动力学联合起来综合考虑是今后三维理论工作所必须解决的问题。

RESEARCH AND NUMERICAL SIMULATION ON THE IONOSPHERIC S_q DYNAMO THEORY

The research progresses during 1883-1990 on the S_q current system of the ionosphere dynamo theory are reviewed. Discussions are made on the importance of research on the S_q current system and its direct and invesion methods. Aslo included are the results and methods given by some principal researchers. The existing problems and further research work are suggested. Although research on the S_q equivalent current system has gained a lot of progresses and 2-D dynamo theory has been much improved, there are still lots of problems in the 3-D dynamo theory and its simulation. So it is urgent in further research work to combine dynamo theory with magnetospheric physics and atmospheric dynamics for improving 3-D dynamo theory and explaining the S_q variation law.
