1·Ultrasonic flaw detection technology combines the characteristic of ultrasonic with modern electronic technology as well as microcomputer technology.
超声波探伤技术是超声波特性与现代电子技术以及微电脑技术相结合的产物。
2·Defects of crankshaft surface and body will produce important effect on engine reliability. This paper probes into flaw detection technology of forging steel and nodular cast iron of crankshaft.
曲轴表面及本体的缺陷，对发动机的可靠性有重要影响，对锻钢和球墨铸铁曲轴的探伤技术进行探讨。
3·The company also owns hardness, metallographic microscope, the mechanical properties of aircraft, non-destructive flaw detection equipment.
公司还拥有硬度计、金相显微镜、力学性能实验机，无损探伤等设备。
4·Ultrasonic flaw detection in large-grained materials is difficult because of multiple scattering from material microstructure (grain noise).
由于粗晶材料中材料微结构引起的散射(结构噪声)，使得超声探伤比较困难。
5·So, the continuous casting was improved, the qualification rate of wide plate during flaw detection was increased.
于是对浇注过程作了改进，使宽厚钢板探伤合格率提高。
