Beer–Lambert lawbiophysical model applicationsModels of primary production in aquatic systems must include a means to estimate subsurface light. Such models often use the Beer-Lambert law, assuming exponential attenuation of light with depth. It is further assumed that the diffuse attenuation ...
这些体均代表了相同的材料,但我们只会在内部域求解 Beer-Lambert 定律,即激光束唯一加热的区域。 如要模拟 Beer-Lambert 定律,我们需要先增加广义型偏微分方程接口,并设定因变量及单位,如下图所示。 实现Beer-Lambert 定律的设定;请注意单位的设定。 接下来,方程本身通过广义型偏微分方程接口实现,如下图所示。方程...

Quantitative spectroscopy is based on the Beer-Lambert law which states that for a homogeneous and non-scattering liquid sample, the amount of radiation absorbed by a sample constituent, A is directly proportional to the product of its molar absorptivity (ɛ), path length (b), and concentration...
叶面积指数(LeafAreaIndex,LAI)是表征植被冠层结构的核心参数。在地面对LAI的间接测量是遥感反演算法验证和改进的重要手段,而目前基于Beer-Lambert定律的森林LAI地面间接测量方法存在着严重的低估问题。本文通过理论分析,指出Beer-Lambert定律在应用到森林叶面积指数测量时,
