控制界限 meaning in English
control limit
Examples
- Ncl ： no control limit is allowed
不允许超出控制界限。 - The calculation formula for control limit of double - side - restricted management chart based on 12 theory was derived , and a calculation example was given
摘要根据基于12理论的双侧控制图原理，推导出基于12理论的双侧控制图控制界限的计算公式，并给出基于12理论控制图的算例。 - In a word , the system break the control limit of traditional class teaching , it inseparable relative with class teaching , out of class reply and so many link , it really embody the teaching guide principle depend on student , it provide an advanced teaching environment based on internet for wide users , it also provide new thought and pragmatic long - range teaching terrace for teaching reform , its study achievement is useful for further going on with teaching reform
以方便用户操作和使用。总之，系统卖破了传统澡堂敦学的控制界限，将课堂教学、课外答疑等各个环节紧密地联系起来，真正体现了以学生为主体约敦学方针，为广大用户提供了一个基于互联网的先进的教学环境，为教学改革提供了新的思路和实用的远程教学平台，其研究成果有助于教学改革的深入进行。 - Control chart is a kind of charts that are used to analysis and determinate whether a process is in - control or not . it use a graph to illuminate the quality variations in production process , and help to find the sources of the variations - common causes or special causes . it is a useful statistical method to keep a process in a stable situation
控制图是用于分析和判断工序是否处于控制状态所使用的带有控制界限的图，它通过图形的方法，显示生产过程随时间变化的质量波动，并分析判断它是由于偶然因素还是由于系统因素造成的，从而提示管理者及时采取相应的措施，消除系统因素的影响，保持工序的稳定状态而进行的动态控制的统计方法。 - Therefore , based on the key project ? esearch on some basic problems on quality control and source tracing in modern manufacture ? ( no . 59735120 ) sponsored by national natural science foundation , a deep research is made in this dissertation its branch subject ? the theory and technology of zero - waste control . the main work and achievements are as follows : 1 . on the basis of the introduction of common quality control methods , some key problems about statistical quality control are elaborately discussed ; a method to decide the quality control line is developed ; a mathematical model based on the sampling plan of multi - variation of product quality is set up ; the process manufacturing condition of quality control chart is discriminated using the theory of fuzzy diagnosis
为此，本文基于国家自然科学基金重点资助项目“现代制造质量控制、溯源若干基础问题的研究” （项目编号： 59375254 ） ，重点对其中的子课题? ?零废品控制理论和技术进行了深入的研究。论文的主要工作和取得的成果如下： 1在介绍了常用质量控制方法的基础上，对统计质量控制的几个关键问题进行了详尽的讨论，提出了质量控制界限的确定方法，建立了基于产品质量多变异的抽样方案的数学模型，利用模糊识别理论对质量控制图工序加工状况进行了判别。
