据《朝日新闻》报道,日本近日开发出检测钢筋混凝土建筑损伤的新方法,一些肉眼看不到的导致损伤的物质通过红外线照射“暴露无遗”。东京大学生产技术研究所开发的新方法是:利用物质具有吸收特定波长光的性质,通过分析建筑物受红外线照射后反射光的波长,调查建筑物的表面物质。然后再用电脑画面以不同颜色分别显示出建筑材料中由海水和路上融雪剂而产生
According to Asahi Shimbun, Japan recently developed a new method of detecting damage to reinforced concrete buildings. Some of the materials that can not be seen by the naked eye are exposed through infrared rays. A new approach developed by the Institute of Technology at Tokyo University of Technology is to investigate the surface material of buildings by analyzing the wavelength of light reflected by infra-red illumination of buildings after they have been used to absorb light of a particular wavelength. And then use the computer screen in different colors were shown in the building materials from sea water and snowmelt on the road and produce
