| 摘 要： | 本文将Ｂｅｅｒ定律，化学平衡原理和数学方法结合起来，较为严格地论证了摩尔比法的原理。同时证明了若以试剂空白为参化液，则无论试剂在所选定的波长λ处是否有显著的吸收，从理论上讲用该法都可得到准确的结果。

| Abstract: | The paper demonstrates strictly the principle of mole-ratio which is usually used to determine the compos- ition of a complex in spectrophotometry by combining Beer's law with the principle of chemical equilibrium and mathematical method.The paper has also proved:no mat- ter what the reagent R has a marked absorption at the wavelength,the value of n:m will be accurate in theory by using this method. |
