以相对论的Xα方程为基础,提出了一种新的计算模型,即耦合表 象下的自旋极化模型。该模型综合地考虑了相对论效应和电子的自旋状态,把处于自旋混合 态的电子并入已有的自旋极化模型中。用此模型计算了第三周期至第六周期的ⅢA~ⅧA原子 的电离势。计算结果与自旋极化模型,自旋非极化模型的计算结果以及实验结果进行了比较 。该模型在一定程度上优于其它计算模型,在核电荷数较大的体系中计算结果更接近实验值 。
本文选取由国际GPS服务中心(IGS)提供的北美中纬度地区GPS网TEC观测数据,通过多通道最大熵频谱分析方法研究了2005年(太阳活动低年)地磁活动平静期间日出和日落时由于日夜交替线的移动而激发的中尺度电离层扰动(MSTID),并统计分析其季节变化特性.结果表明:(1) 日出或日落期间,在中纬度地区经常观测到由日夜交替线移动激发的中尺度电离层扰动.扰动主要沿日夜交替线运动方向传播,平均持续时间约...
地球热层和电离层是近地卫星运行的主要场所,也是空间天气对人类活动影响的重要区域.气辉和极光是高层大气中的重要发光现象,其辐射特性、特别是紫外波段的辐射特性,是高层大气和电离层物理化学过程信息的重要来源.本文详细分析了国外远紫外极光/气辉探测和相应探测器的发展里程,并结合我国相关研制技术和水平,提出了发展星载极光/气辉探测的基本考虑和建议。
