中文摘要：

为进一步发展特种干扰泡沫这一新型多波段无源干扰技术，研究了稳定性强、流动性好的胶质气体泡沫（CGA）对IR／MMW的干扰特性．实验表明，CGA对IR／MMW的干扰能力可达普通干扰泡沫的十几倍．初步分析认为，由CGA气泡的半径小、液膜厚等结构特征产生的界面数优势和全反射优势，是保障CGA优良干扰特性的重要基础．研究结果可为干扰泡沫这一新技术的“涂覆型”使用提供一种更可行、高效的途径．

英文摘要：

The interference characteristics of colloidal gas aphrons （CGA） against IR/MMW were studied to further develop the special interference foam, i.e. a novel multi-band passive interfering technique. CGA is of strong stability and good fluidity. The experiment results show that CGA has much better interference ability against IR / MMW than ordinary interference foam. The theoretical analysis shows that CGA has more interfaces and total reflection advantage due to its structural characteristics such as the small radius of bubble and the thick liquid membrane. These advantages are the important basis of CGA＇ s excellent interference characteristics according to the theoretical analysis. The study provides a more feasible and effective approach for the use of coating interference foams.
