【摘要】 厚度宽容度是变截面工件射线检测的重要参数。本文分析了典型工件的厚度差,以及不同灵敏度级别的厚度宽容度。应用胶片特性曲线、曝光曲线,从实验角度测量了厚度宽容度,并对结果作了分析和讨论。更多还原

【Abstract】 Thickness tolerance is an important parameter in radiographic testing of thickness changed object.The paper analyzed the thickness difference in typical objects,and thickness tolerance required for different sensitivity classes.Using film characteristic curve and exposure curve,the thickness tolerance was measured experimentally,and the result was discussed.更多还原
