With EISCAT radar observations during 1988～1999, the climatologic features of electron densities in the auroral ionospheric Fregion have been investigated statistically and compared with the IRI2001 model for different seasons at different phases of the solar cycle.

利用1988～1999年欧洲非相干散射EISCAT雷达观测数据，对不同太阳活动周相、不同季节的极光椭圆区电离层F区电子密度进行统计分析，研究其气候学特征，并与IRI2001模式比较。

Using a perturbation method, these linearized equations are solved for a composite sphere with the charge densities of the rigid core surface and of the surface layer as the small perturbation parameters. Analytical expressions for the settling velocity and electrophoretic mobility of the composite sphere in closed form have been obtained from a balance among its hydrodynamic, electrostatic, and/or gravitational forces.

以复合粒子之固体核心表面的电荷密度和多孔性表面层内的固定电荷密度为二个微小扰动参数，应用正规微扰法来求解这些已线性化之主导方程式，再藉平衡作用於复合粒子的重力、静电力和流体阻力等三种力后，可得到带电球形复合粒子的沉降速度及电泳可动度的解析形式表示式。
