神奈川大学工程系铃木教授领导的研究组,研制成功了用于测定金属中接触电势差的高灵敏仪器,这使探测金属疲劳在早期出现的裂纹成为可能。在金属表面上出现裂纹将影响它的形状。通过测定对金属(特别是对铝和它的合金)表面形状非常敏感的应力,新仪器能同时测出裂纹的发生和扩 A research team led by Professor Suzuki of Kanagawa University Department of Engineering has developed a highly sensitive instrument for measuring contact potential differences in metals, making it possible to detect metal fatigue in early-stage cracks. Cracking on the metal surface will affect its shape. By measuring the stress that is very sensitive to the surface shape of metals, especially aluminum and its alloys, the new instrument can simultaneously detect the occurrence and expansion of cracks
