摘要 两个强震震涡中心连线的中点处,因为共振和“拍”的作用,会形成“地热涡”,它使得位于其上的地幔与地壳抬升,地温升高(3.2m地温亦升高),因此将其称为“拍地热涡”(简称“拍涡”).本文对近30年出现在我国的“拍涡”进行了统计,结果表明:凡两个强震符合下述条件者:1)两强震的震级差≤1.5级,其最强地震≥6.5级(除1982年12月6.4级例外);2)两强震的震中距相差1500-6000km;3)两强震的时间差≤2个月.半年之内在其“拍涡”的数百公里范围内会出现一块R’%〉100%的强大多雨区,这为水灾预测提供了依据.同时对少数不符合上述条件的个例进行了成因解释. Because of the resonance and the "beat" effect, the mid-point of two seismic vortexes can constitute a geothermal vortex and lift up its over mantle and crust to increase the ground temperature (including the 3. 2m), we describe it as a "beat geothermal vortex" ("beat vortex"). In this paper, the "beat vortexes" appeared during 1980- 2011 in China are investigated, Find that if the two earthquakes match the conditions as follows: 1)The difference is not more than 1.5 in magnitude and the stronger is not less than 6. 5 (excluding the 6. 4 rank one in Dec. 1982). 2) The epicenter interval is about 1500 to 6000 kin. 3)The time difference is less than 2 months. A heavy rainfall area with R'〉100% will be caused within several hundred kilometers around the "beat vortex", which provides a scientific basis for flood forecasting. At the same time, we also discussed the reason for few cases inconsistent with the above conditions.
