摘　　要：针对常用红外烟幕遮蔽能力测试方法存在的问题,提出了一种利用热像仪对红外烟幕遮蔽率进行测试的方法.文中详细介绍了测试的具体方法,引入了等效温度的概念,采用相对测量法,提高了测量结果的准确性,并通过举例对红外烟幕遮蔽率的计算过程进行了说明,该方法简单实用,具有广泛的实用价值.In order to solve the problem exists in the common measuring method of the obscuring ratio of anti-infrared smoke, a method which uses an thermal imaging instrument to measure the obscuring ratio of anti-infrared smoke is proposed. In this paper, the particular measuring method is presented and the concept of equivalent temperature is introduced. Through the use of the relative measuring method, the accuracy of the measured result is improved. The calculation procedure of the obscuring ratio of anti-infrared smoke is illustrated. This method is simple and practical and is of great value to practical applications.
