【摘要】 一种被众多学者承认的论点是：孕震结构是彼此间即相互牵连又有共同成因的断裂构成的。我们知道，前震的地震活动征兆明显增加表明破裂的速率应遵从一种幂律关系。幂律关系的物理内涵是──大破裂是众多小破裂（看作众多子系统）之间的一种相互作用的结果（又称多体互作用）。深入讨论这种互作用是本文的核心。更多还原

【Abstract】 To pregnant with structure of earthquake tie up with each other, the structure hassame cause of formation of breaking. When earthquake prediction the sign of activity ofeaarthquake increase clearly that express the speed of breaking to follow the relation ofpower law that existence prove great breaking in the little crack is a multisystem result ofinteraction. This is the discussing core of the paper.更多还原
