摘要
利用200 ~ 1200nm波长范围内的激光发射机,测定了肯尼亚蒙巴萨县海水和浅层井水两种不同但关系密切的光介质的透射率和总消光系数。结果用兰伯特-比尔定律解释,适用于非常小的浓度范围。结果表明,在638 nm波长下,海水和浅层井水的总消光系数分别为µt = 7.734 (g/ml) -1 mm -1和µt = 127.6 mm -1,两种水的总消光系数呈线性关系。
Transmittance and Extinction Coefficient of Sea and Well-Water in Mombasa County, Kenya
Using a laser transmitter in the range of 200 nm to 1200 nm, transmittance and total extinction coefficients were determined for two different but close related optical media which are ocean water and shallow well water in Mombasa County, in Kenya. The results were interpreted using Lambert–Beer’s law as applied for very small ranges of concentrations. It was established that the total extinction coefficients for two forms of water showed linearity with values of total extinction coefficients found to be µt = 7.734 (g/ml) -1 mm -1 and µt = 127.6 mm -1 at a wavelength of 638 nm for ocean water and shallow well water respectively.
