Williamson valves produced high quality valve and fitting products by adopting advanced quality control techniques and innovative inspection facilities in 1975 从1975年开始，通过采用先进的质量控制技术和检验设备的技术更新，威廉姆森阀门开始生产高质量的阀门和管件产品。
However , the common problem that still exits in these techniques is how to discriminate the variables that are really being out of control when the multivariate control charts are signaling 这些多元质量控制技术存在的共同问题是:一旦发现失控信号，由于相关性，很难判断哪个/哪些变量出现问题。

Coordinates and implements the activities for a group of employees , developing the controls that insure that the products satisfy the preset quality standards , using adequate control techniques and quality system requirements 协调和执行一组员工的活动，制订质量控制规定和流程，借助完善的质量控制技术和质量系统要求，确保产品符合预定质量标准。
The accuracy and reliability can be improved greatly if the appropriate quality control techniques are used to analyze and control factors during inspection process such as sampling , inspector , equipment , inspection data , defect evaluation , and so on 未用适宜的质量控制技术对检测过程的抽样、检测人员、检测仪器、检测数据和缺陷评定等因素进行分析与控制，可以提高检测与评价结果的准确性及可靠性。
The theories and application methods of some quality control techniques are introduced briefly , such as statistical sample , measurement system analysis , evaluation of measurement uncertainty , fault tree analysis bind even tree analysis , and their application in ndt & e is discussed 简要介绍了统计抽样、测量系统分析、不确定度评定，故障树与事件树分析等质量控制技术的理论及应用方法，并结合无损检测与评价过程进行了讨论。
The key technologies , such as mixing , such as mixing , transportation , pumping , curing , etc . for engineering application of hplc are analyzed systematically ; the program of the designation of hplc was made out and the quality control method is put out 系统研究了高性能轻集料混凝土的搅拌、运输、泵送、浇注、振捣和养护工艺等工程应用的关键技术，研制开发出高性能轻集料混凝土配合比设计程序，提出高性能轻集料混凝土的质量控制技术方法。
In this paper , the so preparing self - compacting concrete with low and middle strength using super fine mountain sand artifical sand and phosphorus slag is studied systemically . through the study the influence of the shape , the proportion of the dust and the grade of sand to the workability and the mechanical property of self - compacting concrete , it is found that super fine mountain sand artifical sand are not suit to prepare low and middle strength self - compacting concrete , but when they are combined and the additive and assistant band material are used , c20 - c40 high performance self - compacting concrete is prepared ; the corresponding additive is developed to solve the delamination caused by the low proportion of banding material ; the evaluating system for the workability of low and middle strength self - compacting concrete is built ; the controlling method for production , construction and curing was set up . and the result of the research is applied into several projects 通过分析特细山砂和机制砂的颗粒形态、粉末含量、颗粒级配等特性对自密实混凝土的工作性能和力学性能的影响，发现特细山砂、机制砂不宜单独用于配制中低强度等级自密实混凝土，宜将特细山砂和机制砂进行合理复配，并选择合适的外加剂和矿物掺合料，优化配合比设计，可生产c20 c40中低强度等级自密实高性能混凝土；研制开发出了具有高效减水、保塑、抗离析功能的外加剂，有效解决了中低强度等级自密实混凝土由于胶凝材料用量少而出现的离析、泌水问题；应用正交设计方法，对因素和水平进行合理选择，确定了生产中低等级自密实混凝土的最优配合比；建立了中低强度等级自密实混凝土的工作性评价体系；提出了生产、施工及养护的质量控制技术方法。
For the purpose to assure the quality and to achieve the expected technical performances we have formulated a detailed nda standards preparation scheme , and studied certain important quality control techniques in preparation and characterization of nda standards , those are the foundations in developing nda standards 我们制定了上述四套nda核标准样品的详细研制方案，研究了研制过程中一些重要的质量控制技术，这些研究是研制高质量的nda核标准样品的重要基础。
In this paper , thoroughly discussed are construction technology and quality control of high - filled embankment based on the joint research project , research on construction technology and quality control of high - filled embankment , by guangxi highway management bureau and college of civil engineering , hunan university 本文以广西壮族自治区公路管理局和湖南大学土木工程学院联合承担的科研项目“高路堤施工技术与质量控制研究”为依托，深入研究了高填石路堤施工技术及质量控制技术。
