介绍了一种新型的无色渗透检测方法，与着色渗透检测和荧光渗透检测不同的是，其使用的是一种环境友好型无色透明的渗透剂，因此检测过程比较简单，只需渗透、观察两个操作过程。通过试验分析，发现此无色渗透检测方法适合于检测表面光亮的零部件，对线型、面型缺欠的检测灵敏度较高。

This paper introduces a new kind of colourless penetrant testing. Differing from the conventional colour contrast techniques and fluorescent techniques, the colourless penetrant it uses is a kind of environmentally friendly and transparent penetrant, so the testing process is simple and is of only two operations of penetrant and viewing. According to experiment and research, it is concluded that colourless penetrant testing is suitable for the inspection of surface shining components, and is high sensitivity for the detection of linear and planar imperfection.
