摘　　要：在窄矩形横截面入射光束被平凸透镜会聚后，其入射光线全部沿直线型光导池的子午面反射行进的情况下，推导出光导池吸光度表达式．按此式用计算机进行数值计算并作图，发现吸光度Ａ与待测样品浓度和光导池的长度均成很理想的线性关系．With a narrow rectangular cross-section incident light beam focused by a flat-convex lens and all the lights propagating through straight-line-type optical wave-guide cell(OWGC) by total reflection within its meridian planes, an expression is induced for the calculation of absorbance of OWGC. According to this expression and give values of parameters, numerical calculation is conducted and figure 3 (a)to (d)are drawn. Very good linearities of the dependence of absorbance A on the concentration c of specimens and the length of the OWGC are obtained for all the linear lines.
