动力设备运行过程中,其力学性能必须不断检查。要求检查是高效的、可靠的以及测量稳定的,并使各种影响因素达到最小程度。所以,对于金属力学性质无损探测检查仪的研制(包括各种零件和动力设备接点的硬度无损探伤仪的研制)是一个重要的问题。根据某些固定特性,强度性质无损探测法可以分成三种:即力学检查法,电磁检查法和音响检查法。动力设备的金属强度性质无损检
Power equipment operation, its mechanical properties must be constantly checked. Inspection is required to be efficient, reliable and stable in measurement, with a minimum of various influencing factors. Therefore, the development of nondestructive detection apparatus for metal mechanical properties (including the development of non-destructive flaw detectors of various parts and power equipment joints) is an important issue. According to some fixed characteristics, the strength and nature of nondestructive detection method can be divided into three kinds: mechanical examination, electromagnetic examination and acoustic examination. Power equipment metal strength properties of non-destructive testing
