起核心作用，氢水泡成长并且裂开试验性地并且理论上被调查了。结果证明那原子氢在金属导致极多的空缺。Thesuperabundant 空缺和氢总数进 ahydrogen 空缺簇(微洞) 。在微洞的 Thehydrogen 原子成为能稳定簇的氢分子。Andthe 氢水泡起核心作用。与空缺和氢原子的入口，水泡原子核成长，在洞的压力增加。当氢压力在水泡上导致的压力直到连贯的力量时，裂缝将从水泡的墙开始。

英文摘要：

The nucleating, growing and cracking of hydrogen blister have been investigated experimentally and theoretically. The results show that atomic hydrogen induces superabundant vacancies in metals. The superabundant vacancies and hydrogen aggregate into a hydrogen-vacancy cluster （microcavity）. The hydrogen atoms in the microcavity become hydrogen molecules which can stabilize the cluster. And the hydrogen blister nucleates. With the entry of vacancies and hydrogen atoms, the blister nucleus grows and the pressure in the cavity increases. When the stress induced by hydrogen pressure on the blister is up to the cohesive strength, cracks will initiate from the wall of the blister.
