| 摘 要： | 利用WGD-8A型多功能光栅光谱仪测量了不同汽油体积含量的乙醇汽油溶液对波长为300.0～430.0 nm光的吸收光谱,分析了乙醇汽油吸光度和汽油浓度的关系,在稀溶液吸光度的朗伯-比尔定律基础上,进一步研究了2种高浓度混合溶液吸光度的计算方法,并得出了入射光波长为377.0,382.0,391.5,410.9 nm时乙醇汽油的吸光度与汽油体积浓度的关系式.

| Abstract: | The Absorption characteristics of ethanol gasoline has been explored with a WGD-8A grating spectrometer.The Absorbance of ethanol gasoline of different concentrations has been measured in the range of 300.0~430.00 nm.Ethanol gasoline has strong Absorption at wavelengths shorter than 415 nm.Absorbance of different concentrations of ethanol gasoline at wavelengths of 377.0,382.0,391.5,410.9 nm has been calculated.Formulas of Absorbance are given as functions of concentration and wavelength.We extend the Lambe... |
