摘　　要：为提高KNO3/Mg-Al红外诱饵剂红外辐射强度,采用药剂中添加硼(B)粉的方法,借助远红外热像仪对诱饵剂燃烧及红外辐射特性进行了实验研究。结果表明,添加B粉后诱饵剂的质量燃速、燃烧温度、辐射亮度增大。当B粉含量由0%增加到2%时,诱饵剂的质量燃速从0.394 g·s-1提高到0.564 g·s-1。当B粉含量由0%增加到4%时,燃烧温度和辐射亮度分别从727.71℃、995.68 W·m-2·sr-1增加到1046.19℃、1681.59 W·m-2·sr-1。辐射强度随B粉含量增加呈现出先增加后减小的趋势,B粉含量为4%时辐射强度达到极值2.64 W·sr-1,显示一定比例B粉可有效提高诱饵剂的质量燃速、燃烧温度及红外辐射特性。To improve the infrared radiation intensity of KNO3/ Mg-Al decoy,the combustion and infrared radiation characteristics of the decoy were experimentally studied via the method of adding boron powder in the decoy by a far infrared thermal imager. Results showthat the mass burning rate,combustion temperature and radiation radiance of the decoy increase by adding boron powder. With the content of boron powder increases from0% to 2%,the mass burning rate of the decoy increaseing from0. 390 g·s^-1to 0. 564 g·s^-1. When the content of boron powder increases from0% to 4%,the combustion temperature and radiation radiance increase from727. 71 ℃,995. 68 W·m^-2·sr^-1to 1046. 19 ℃,1681. 59 W·m^-2·sr^-1respectively. With increasing the content of boron powder,the radiation intensity reveals the trend to increase firstly and then decrease. When the content of boron powder is 4%,the radiation intensity increases to the maximumof 2. 64 W·sr^-1,revealing that adding a certain proportion of boron powder can effectively improve the mass burning rate,combustion temperature and infrared radiation characteristics of the decoy.
