我们描述了精确的光学衰减测量LAB的液体稀释器使用定制的光度计可变路径长度高达2米。结果线性烷基苯（LAB）和LAB为基础的液体澄清剂在405，430，450和470 nm的波长。对于这些测量，非常小心地控制液体和添加剂的纯度，以及光度计的材料以控制污染。这些数据应该是有价值的大型探测器的设计，如地下中微子探测器，使用这些材料作为媒体。
We describe precise optical attenuation measurements of LAB based liquid scintillators using a custom-built photometer with variable pathlengths up to 2m. Results are presented for linear alkyl benzene (LAB) and LAB based liquid scintillators at wave lengths of 405, 430, 450, and 470nm. For these measurements much care was exercised to control the purity of the liquids and additives, as well as the materials of the photometer to control contaminations. These data should be valuable for design of large detectors, such as underground neutrino detectors, using these materials as the media.
