本文提出了多次倍率减差分光光度法直接测定多组分混合物含量的原理。并以APC片为对象进行了验证。还对该法的应用及选择测定波长的原则进行了讨论。
In this paper, the principle of direct determination of the content of multi-component mixture by multiply-rate reduction spectrophotometry is proposed. And the APC chip as the object has been verified. The application of this method and the principle of choosing the wavelength of measurement are also discussed.
