摘要: 求出了有氢和无氢条件下稳定解理裂纹核尺寸ａｃ（Ｈ）和ａｃ由于氢促进局部塑性变形，氢降低表面能以及裂纹核中存在氢压，故ａｃ（Ｈ）＜ａｃ．这就表明，氢能促进解理裂纹的形核以及稳定化．

关键词 ：氢促进解理, 裂纹形核

Abstract：The expressions of critical size of a stable cleavage crack nucleus in the absence and presence of hydrogen are given respectively as follows:It could be concluded that ac(H)

Key words： Hydrogen-facilitating cleavage Crack nucleation
