日本长崎水产公司制成了一种可用于测定鱼鲜度的激光仪器。该仪器用激光照射鱼的眼睛，再从鱼眼反射光线的不同来测定鱼的新鲜程度。原来，刚死的鱼眼睛巨射光量最多，周波数最高；随着鱼死亡时间的延长，鱼眼反射光量逐渐减少，周波数也慢慢下降。这样，就可根据鱼眼反射光量? Japan Nagasaki Aquaculture Company made a laser apparatus can be used to determine the freshness of fish. The instrument uses a laser to illuminate the eyes of the fish and then determine the freshness of the fish from the difference in the light reflected from the fisheye. It turned out that the fish died just the largest amount of light jets, the highest number of cycles; as the fish died longer, fisheye reflected light gradually decreased, the number of weeks is also slowly declining. In this way, according to the fisheye reflect light?
