摘要
提出并采用了一种研究GM管失效规律的新方法,利用该方法研究了两种GM管的失效规律,并据此确定其使用寿命为18～20年,在此期间的失效率分别为5×10-6/h和4×10-6/h。
The reliability of GM counter tubes is described by useful time before failure - life and failure rate during life. A new method to study the failure regularity of GM counter tubes was presended. Using this method, the failure regularity of two kinds of GM counter tubes are studied. According to the failure regularity, the useful life and failure rate is determined. The conclusion is that the useful life is 18 -20 years and the failure rate is 5 × 10-6/h and 4 × 10 6/h respectively .
