Abstract : the attention has focused on quantifying the capability of nondestructive testing ( ndt ) system for guaranteeing structural safety through damage tolerance analysis. a method of reliability assessment for engine blades ndt is presented, which can determine exactly the probability of flaw detection （ pod ） and assess the probability of flaws missed （ pom ） in the engine blades, as well as control the largest size of the flaws missed at inspections with high probability of flaw detection and confidence level. this method also raises the flaw detection probability and prevents the flight accidents caused by the missed flaws in engine blades
文摘:提出了一種發動機葉片無損檢測可靠性分析方法，利用該方法可以有效地提高葉片中裂紋（缺陷）的檢出概率（ pod ） ，並能對裂紋的漏檢概率（ pom ）進行準確地評估和控制，使因葉片裂紋漏檢而引起發動機故障的可能性降至最低程度，從而確保發動機的安全運行；該方法簡單方便，易於工程實施和應用。 -
Generally, the size of the flaw is distinguished by x - ray radiographic system, described by density resolution and space resolution, but it is proved experimentally that the space resolution is not always high while the density resolution is high, and the density resolution is not always high while the space resolution is high
通常x ?射線成像系統可分辨疵病的大小，常用密度解析度和空間解析度來描述，但試驗證明，當系統的密度解析度高時，系統空間解析度不一定高，而空間解析度高時，系統的密度解析度也不一定高。
