比尔-朗伯定律(Beer-Lambert Law),又称比尔定律、朗伯-比尔定律或光吸收定律,是光学吸收的基本定律。它描述了物质对某一波长光吸收的强弱与吸光物质的浓度及其液层厚度之间的关系。该定律指出,当一束平行单色光垂直通过某一均匀非散射的吸光物质时,其吸光度(Absorbance, A)与吸光物...

lambert -beer定律 The Lambert-Beer law, also known as Beer-Lambert law, is a fundamental principle in spectroscopy that relates the absorbance of light by a substance to its concentration and path length. According to this law, the absorbance of a solution is directly proportional to the ...
Beer, August, German physicist, 1825-1863. Beer-Lambert law - the absorbance of light is directly proportional to the thickness of the ligand through which the light is being transmitted multiplied by the concentration of absorbing chromophore. Beer law - the intensity of a color or of a lig...
The units of concentration and path length must be specified. See Absorption Coefficient . Note − In Europe, it is called the Law of Lambert-Beer. (DeLevie R (1996) Principles of quantitative analysis. Mc-Graw-Hill Higher Education, New York; Willard HH, Merritt LL, Dean JA (1974) ...
The Beer-Lambert Law, also known as Beer's Law, describes the relationship between the concentration of a substance in a solution, the path length of the sample, and the absorbance of light by that sample. It is mathematically represented as: ...

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 (c) [2...
朗伯比尔定律（lambert-beer law）lambert-beer law The Lambert (Lambert) law states that the ratio of light absorbed by a transparent medium is independent of the intensity of incident light, and that each equally thick layer absorbs light of the same value on the optical path.Catalog 1 concepts...
Beer-Lambert Law Introduction The Beer-Lambert law (or Beer's law) is the linear relationship between absorbance and concentration of an absorbing species. The general Beer-Lambert law is usually written as: A = a(lambda) * b * c where A is the measured absorbance, a(lambda) is a wavel...
