摘要：
The configuration and the detection of solution concentration are the basic steps of scientific research. Most of solution concentrations can be obtained by indirect method. In this paper, by using the numerical relationship known between the alcohol concentration and refractive index, the relationship between the alcohol concentration and spectral transmission characteristics of the resonance peak can be calculated. The relationship between transmittance and concentration of alcohol solution can be described in a certain nonlinear mathematical expression, which is simple and inversible. Such method provides a novel way to detect alcohol solution concentration and puts forward the expression of the nonlinear correction. The linear relationship that has been using for long time is revised. And it can be reasonable to predict relative parameter that is unknown. This paper provides a new way to reasonable configuration and application for the concentration of solution.
