Among them:a: absorbency, k: aspirated index, b: liquid layer’s thickness, c: solution’s consistency, i0: incident light’s strength, i: transmit light’s strength.
According to the above formulas, under the condition of the certain liquid layer’s thickness and incident light’s strength, as long as test the strength of transmit light which goes through the liquid, so we can calculate the consistency of the solution.
