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.
