It is found that there exist quasi-45 d,quasi-23 d and quasi-14 d low-freque ncy precipitation over the plateau and that the lower of the frequency,the more likely of their propagation from south- and east-side of the plateau to the pl ateau itself,and v.v.

研究表明，准45 d、准23 d和准14 d等3类低频降水的频率愈低，低频降水愈趋向于从高原东侧和南侧向高原传播；反之，频率愈高，低频降水愈趋向于由高原向高原东侧和南侧传播。

Due to the complicated nature of the coupling processes between polar ionosphere and magnetosphere as well as thermosphere, however, here still remain lots of questions need to be further studied, such as the relationship between convection electric field and polar ionosphere, the mechanism of auroral particle precipitation, the origin of magnetospheric particles and so on.

如，极区电离层背景变化的气候学特征，对流电场与极区电离层的相互作用关系，以及极光区粒子沉降的机制和磁层粒子起源等等。
