基于Duysens对吸光度平坦化现象的描述，分析了圆柱形结构的测量吸光度、圆二色性、旋光度和其他光谱特性中的失真幅度。模型计算是针对具有与溶剂相同折射率的各向同性颗粒进行的。对于任意半径和高度的圆柱体，对于入射辐射，无论是随机取向还是垂直取向，都可以得到圆柱体粒子中的生色团与溶液中孤立生色团的光学性质相关系数的精确积分表达式。具体情况下的积分的数值计算结果表明，对圆柱体的高度，半径，消光系数和方向的平坦化的依赖。
An analysis is made of the magnitude of distortions in the measured absorbance, circular dichroism, optical rotation, and other spectral properties of cylindrical structures based on Duysens' description of the absorbance flattening phenomenon. The model calculations are made for isotropic particles having the same refractive index as the solvent. Exact integral expressions for coefficients relating optical properties of chromophores in cylindrical particles with those of isolated chromophores in solution are obtained for cylinders of any radius and height which have either random or perpendicular orientation with respect to the incident radiation. The results of numerical evaluation of the integrals for specific cases are presented to demonstrate the dependence of flattening on cylinder height, radius, extinction coefficient, and orientation.
