【摘要】 研究钢的裂纹,要确定裂纹的特征和产生裂纹的影响因素。经过分析,初步确定出裂纹产生的原因,然后采取改进措施,反复实践,直到最终消除裂纹。提出研究钢的裂纹,要注意结合各种专业知识,善于积累现场经验和借鉴他人的工作成果;掌握数理统计及物理检验的方法,提高调查研究的能力等方面的建议。更多还原

【Abstract】 To research on cracking of the steel,it is necessary to identify the crack characteristics and the elements responsible for development thereof. Based on related analysis,the causes for development of the cracks are initially identified,and accordingly actions for improvement are taken. Thanks to repeated efforts,the cracks have been finally eliminated. Proposals for researching on cracking of the steel are put forward,including appropriate application of knowledge of all the disciplines concerned,gathering site experiences and successful experiences of others,getting command of relevant mathematic statistic methods and physical testing methods as well as enhancing research ability,etc.更多还原
