| 摘 要： | 本文着重考察了日全食时F_2层的形态,对其形成机制进行了理论探讨。按实测的形态特征可将F_2层分为三个区域,在该三区中光化学与动力学效应的相对作用是不同的。作者认为,日食时电子温度变化引起电离层等离子体的热收缩,是这次日食时F_2层形态形成的主要原因。

| Abstract: | The morphology of F2 layer during the solar eclipse is examined, and the mechanism of its formation is discussed theoretically. It is found that there are three different types of the electronic density behavior in F2 layer. Correspondingly, this layer can be divided into three regions according to the relative effects of photochemistry and dynamics. The authors consider that the thermal contraction of the ionospheric plasma produced by the change of the electronic temperature may be the principal cause of the morphological behavior of F2 layer during this solar eclipse. |
