摘　　要：材料对激光吸收的研究工作对激光加工的发展有着非常重要的意义 .而吸收率测量方法的研究是材料对激光吸收研究工作的基础 .从量热的角度出发 ,利用传热学中的集总参数法建立了测量吸收率的方法 ,设计了相应的试验装置 ,并测量了几种常用工程材料对激光的吸收率 .The research for the absorptance of materials is significant to the development of laser material processing. The measurement method is the foundation of the absorptance research. In this paper the lumped method based on heat transfer is established for the absorptance of laser,and the measuring apparatus is also built up. As examples,the absorptance of laser is measured for several ordinary engineering materials.
