摘要
当一束单色光照到某物质时,根据朗伯——比耳定律,在测得入射光强与出射光强之后,该物质的含量可以测得。对不同灰度不规则面积的样片,通过扫描,可自动分类测出。经计算机处理,最后自动打印结果。
According to the law of Lambert-Beer, when a monochromatic light shines on a mattr, the guantity of the matter can be surveyed after incidencd light intensity and outgoing light intensity being surved. For different grey scale no rules area, it can be auto-classify surveyed through being sweeped. It can automatically print the result with computer's operating.
