It proves , the computer could help operator to make ultrasonic testing and deserve popularizing 说明利用计算机可以很好的辅助操作人员进行超声波探伤,具有应用推广价值。
The blocks were the same with the ultrasonic testing of wheelset in rolling stocks , the benchmark for the spot inspection was provided 该试块适用于在役轮轴超声波探伤，为现场检测提供了统一的探伤基准。
Abstract : this paper discusses the problem of the acoustic distance compensation in the process of ultrasonic wave flaw detections . the digitized schemes is put forward 文摘:探讨关于超声波探伤过程中涉及到的声程补偿问题，并提供出相应的数字化解决方案
It has set up physical & chemical inspection center , helium leakage indicator ( shimadzu , made in japan ) lab , ultrasonic crack detector lab , x - ray fault indicator lab 已建有理化检验中心、 （日本岛津）氦质普检漏室、水压泄漏检测室、超声波探伤室、 x射线探伤室。
Ultrasonic flaw detection technique is used broadly in fields of the large - sized boiler , group of electromotor , petroleum pipeline , bridge , aviation and spaceflight , and so on 超声波探伤技术在大型锅炉、发电机组、输油气管道、铁路、桥梁和航空航天等领域有着广泛的应用。
The circuit module satisfactorily solves the existing demerits of low anti - interference capacity and low sensibility of traditional ultrasonic defect detectors when doing on - line inspection 该电路模块较好地解决了超声波探伤在在线检测时存在抗干扰能力差、灵敏度低等缺点。
Currently , methods of radiation testing , magnetic particle crack testing , penetration testing , eddy current testing and ultrasonic testing ( ut ) have been wildly used by the industries 目前常用的无损检测方法有五种：射线探伤、磁粉探伤、渗透探伤、涡流探伤和超声波探伤。
Abstract : the irrelevant signals in ultrasonic testing of cast steelrollers are described including their occurence mechanism , the calculation and experiment for their positions , and their removal method 文摘:介绍铸钢轧辊超声波探伤中非相关显示的出现机理、出现位置的理论计算和试验分析及其排除方法。
The development of half axle block used for ultrasonic testing of rd2 , the fast vehicle and df4 axle in rolling stocks was mainly introduced , the main specification and the manufacture technology were also introduced 摘要主要介绍了rd2 、提速车和df4轴型超声波探伤半轴试块的研制，同时介绍了主要的技术要求及制作工艺。
