【Abstract】 According to the effection of hydrogen to the crackle’s forming in metals,some important functions of fracture strain--fracture probability,reliability,and lifetime are discussed.The emphases based on the stack model of the wrong place and detailed calculation were posted on insearching distribution function of the macroscopic crackle caused by hydrogen.Also the fracture probability of the crackle caused by hydrogen has been insearched.更多还原
