磁力探伤中新的缺陷显示方法──缺陷显示板

One New Method of Magnetic-Field Testing Fault Indication Board

介绍了一种新的磁力探伤显示装置─—缺陷显示极的原理及其应用，说明其可代替现有的磁粉和磁悬液，灵敏度高于干磁粉，接近磁悬液，A型试块可清晰显示。

It describes the principle and its application of the defect indication board as a new method of nondestruc tive detection for ferromagnetic material. It workes as the magnetic-particle and magnetic liquid, while it is more sensitive than magnetic - particle and is equal to that of the magnetic liquid The testing block result is shown clearly.
