摘　　要：现代飞行器广泛采用机内测试(Built～intest,BIT)技术,以便对其内部故障进行自动检测、诊断和隔离,但是常规BIT面临诊断能力不足和诊断模糊性等问题,导致BIT虚警率高,难以有效发挥其应有的作用。本文论述了BIT虚警的基本理论、虚警的危害及现状,并从BIT虚警产生的原因分析入手,提出了解决虚警问题的一些方法和措施。The buih-in test （BIT） technolo- gy which can automatically detect, diagnose and isolate the inter-fault is widely used in the modem aircrafts. But the normal BIT faces the problems of deficient diagnostic capability and diagnostic ambiguity, which will cause a high false alarm rate and BIT can not be used in the modem weapon system effectively. The basic theory, the harms and the status of the BIT false alarm are discussed in this paper. Some methods and measures are put forward by analysis of the reasons of BIT false alarm.
