Radiation protection evaluation of harbin pharmaceutical factory ' s industrial x - ray flaw detection room 射线探伤室的辐射防护评价
The noise of x - ray system is researched and the method of reducing the noise is taken up due to the environment of factory . 4 研究了x射线探伤图像中噪声的来源与消除方法，并根据工业实际生产条件，采用了相应的消噪方法； 4
This paper mainly research methods and technological problems that discern of drawing and recognizing fault from picture of ray - defect film with computer 本文主要研究用计算机对射线探伤底片图像的缺陷提取与识别的方法与技术问题。
Abstract : this paper ues the example of the gas processing plant ofyacheng 13 - 1 gas field project to intoduce the type of protections in operation 文摘:以崖城13 - 1气田陆地处理厂工程施工为例，介绍用射线探伤所应采取的防护措施，以确保操作人员的安全。
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。
Abstract : by a discussion on k value , the radiographic technology for thebutt welds in standard elliptic sealing heads consistent with current standards and regulations is presented 文摘:围绕k值展开讨论，提出一种符合现行标准、规程要求的标准椭圆封头拼接焊缝的射线探伤工艺。
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。
The measurement of defect and the common image processing methods are realized , such as histograms showing , invert transform , fake - color transform and curve transform . 3 设计并实现了x射线探伤图像中缺陷尺寸的自动测量及一些常用的图像处理算法，如：灰度直方图显示、负像、伪彩色以及锐化等； 3
