By site inspection , microscope analysis of broken hole, OM, SEM, EDAX of sample of broken wall and H2S content measurement, we confirm that the reasons of the accident is the hydrogen brit-tleness caused by water solution of H2S corrosion.

• 通过现场勘察、破口分析、断口取样、金相检验、电镜和能谱分析、H_2S含量测定,确认钢瓶爆破的原因是H_2S水溶液腐蚀钢瓶产生氢脆所致。
