对于声放射检测技术,我们是陌生的。我们接受“声放射无损检测装置的研究”任务后,试图将其分解成两个步骤来完成。首先通过简捷的途径获得声放射信号,即称原理性试验。然后在此实践的基础上,研究有关声放射检测的各种实用仪器或系统。目前我们仅就原理性试验作了一些工作,草装了一台SFS—1型声放射检测仪,并准备进行第二个步骤的工作。 We are unfamiliar with acoustic emission detection technology. After we accepted the task of “Researching Acoustic Nondestructive Testing Devices”, we tried to break it down into two steps. First of all, through a simple and easy way to obtain acoustic emission signal, that is, the principle of experiment. Then, on the basis of this practice, various practical instruments or systems for acoustic emission testing are studied. For the moment, we have only done some work on prototype tests, weaving out an SFS-1 acoustic emission detector and preparing for the second step.
