1·The results show that the defaults places can be exactly determined by penetrant method which is more visual and accurate than acid leaching method.

结果显示，表面渗透探伤法能准确确定连轧坯和轧后钢板表面缺陷的位置。与酸浸法相比，表面渗透法更加直观、准确。

2·Ultrasonic detection of defects in heat-affected zones of stainless steel pipe welds is discussed. The feasibility of the method is verified by penetrant inspection of dissected pipes.

本文讨论不锈钢管道焊缝热影响区内缺陷的超声波检测方法，应用着色渗透探伤对解剖后的样品进行了验证，证明超声波探伤法的可行性。
