It indicates that the extinction capability and concentration of bubble solvent can seriously influence the light absorption in some wavebands, bubbles can change the direction of light propagation and reduce the energy density, the transmission intensity and light energy decrease rapidly with the increase of times that the light passes through the bubbles, and bubbles′ floating nature can cause the uncertainty in the emergent ray direction and energy distribution.

结果显示：泡沫溶液的溶质/溶剂的消光能力、浓度等对特定波段光波的吸收产生关键影响；泡沫通过改变光线的传播方向，大大分散出射光线的能量密度；随着光线穿过泡沫液膜界面的次数增多，透射光强迅速衰减，透射能量迅速下降；其漂浮运动还将导致出射光线方向和能量密度分布的不确定性。
