摘　　要：光导池吸光度表达式的推导与计算──小矩形横截面入射光束刘占军，王云飞（中国科学技术大学应用化学系，合肥，２３００２６）关键词光导池，全反射长毛细管池，吸光度表达式魏磊等［１］分别提出全反射长毛细管池（ＴＲ－ＬＣＣ）中按子午光线和螺旋光线反射行进时的好...With small rectangular cross-section incident light beam(SRCSILB) focused by a flat-convex lens and all the lights propagating through a straight-line-type optical wave-guide cell(OWGC) by total reflection within its meridian planes,an expression was induced for the calculation of absorbance A of OWGC.According to this expression and a number of given parameters,numerical calculations were conducted and Fig.3 was drawn.Very good linearities of the dependence of A on the concentration C of specimens and the length l of the OWGC are obtained for all the linear lines.These results indicate again that Wei Lei et al.and Dasgupta's conclusion of nonlinearities between A and C or l is not unconditionally tenable.
