摘要
本文对强震前有时出现的大气偏红散射、赤日、红月等现象的成因进行了探讨。指出震前地壳中破裂增多,导致土壤气溶胶在大气中的增多,会使大气的选择性散射增强,引发上述现象。震前高浓度气溶胶粒子造成的衍射还会使日轮、月轮显得更大,而气溶胶浓度增大造成的空气折射增强会使日落时间延长。
Red-inclined scattering may show before strong earthquakes,as dark-red Sun and red Moon.Fractures increasing in the crust before quakes lead to the increase of soil aerosol in the atmosphere,so the selective scattering of the air increases and the scenes mentioned above show.The diffraction of the light passing by aerosol particles makes the Sun or the Moon look bigger,and the increasing refraction caused by aerosol increasing makes the sunset longer.
