摘　　要：本文对大地震前(数月至一两年前)大范围低温与大震间的关系进行研究。确立了这种关系的普遍性;并对这种寒-震机制做出解释:震前地壳内裂隙增多,使大量(土壤)气溶胶进入大气,从吸收、反射太阳入射辐射及作为水蒸气凝结核造成降水两方面导致低温。据此对汶川大震前的南方雪灾成因进行了探讨。The paper analyzed the relationship between low temperature showed in large areas （several months to one or two years before） and strong earthquakes. These phenomena can be well explained by the growing in number of （soil） aerosol raised into the atmosphere from the Earth because of the increasing of fractures in the crust before earthquakes. The aerosol would reflect and absorb the radiation of the Sun, as well as coagulate water vapours to precipitate, so the temperature went down. The reason for the forming of snow disaster in southern China before Wenchuan Earthquake was also discussed according to the mechanism related above.
