摘　　要：应用概率统计理论推导出现行电站焊接抽查方法的特性函数,澄清了与该抽检法有关的诸概念,并据此分析估计了现行抽检法在典型工程条件下的质量控制水平和范围,为现行抽检法的正确应用和改进提出若干建议。Using the probability statistical theory, the characteristic function of the current sampling method for non-destrutive test of power plant pipe weldment is derived and, with which, the concepts con- cerning this sampling method can be quantified and the correct application and improvement of the current sampling method are suggested.
