朗伯比尔定律

采用o衍射光作为样品测量光束，根据朗伯比尔定律对汽车尾气中HC、CO和CO2的含量进行在线监测；

The o-diffracted light is used as the signal light to online measure the concentration of HC , CO , CO_2 in the auto gas based on Lambert-Beer law .

该方法基于朗伯比尔定律，提取相应的脉动动脉血液的吸光度，由这些吸光度组成的光谱，经过傅立叶变换提取需要的频谱信号，识别出动脉血液脉搏波。

The method is based on Lambert-Beer Law , extract the corresponding pulse of arterial blood absorbance . The Spectrum formed by these absorbance , after Fourier transform to extract the spectrum of the signal , could identify the arterial pulse wave .

光谱生化分析的理论基础就是朗伯比尔定律，分析了影响朗伯比尔定律的一些因素，以及吸收光谱与光谱带宽之间的关系。

The factors influencing the Lambert Beer law are introduced . And the relation between absorption spectra and the spectral bandwidth is analyzed .

但是，对于混合溶液而言，有许多客观存在的因素会对朗伯比尔定律的结果产生影响，本文分析了干扰朗伯比尔定律的四个因素，并针对其中的化学误差和噪声影响两个因素展开了讨论。

However , for the mixed solution there are some objective factors which will have a negtive effect on the result of Lambert-Beer Law . This paper analyses four reasons about that and discusses two of the reasons which are chemical error and noise influence .
