【摘要】 用不透明圆盘模型计算了两粒子在同轴条件下的成象光强，计算结果表明，散射光的作用将使粒子象象质变坏，象畸变情况与粒子间的平均远场数有关．在乎均远场数Ｎ＝０．１附近影响最大，称该区为强影响区；此外，小粒子信号容易丢失．更多还原

【Abstract】 Disc-particle model is used to calculate the imaging light intensity of two on-axis payticles, and results show that the region near N=0.1 has effective interaction of two particles.Because of scattered light of particles, the image and dthected figure of particles have been distorted which relates to averaged number of far-field particles; small particle signsls can be missed with easy.更多还原
