目前各种微波小功率计量自动控制系统都是针对特定配置研制的,缺乏通用性和扩展性,造成重复开发。针对此问题,基于VC.net2003平台和VPP虚拟仪器软件规范,提出了设备数据封装协议,从而实现了基于“数据驱动计量”的通用微波小功率自动计量系统。目前,系统可以完成十多家知名企业的几十种功率座和功率计产品自动计量检定。通过扩展向导,用户可自己添加需要扩展的仪器,并且具备了数据输入输出、数据检测、数据管理、数据对比、设备管理、即时流程控制、不确定度分析等多项实用功能。该系统提高了实验室功率校准的准确度、速度,提高了效率。 相似文献

目前,许多企业正在积极筹备建立或已经建立了计量检测体系/测量管理体系。该体系的建立对企业完善计量检测和提高计量管理水平都有很大的推动作用。笔者在参与部分企业的计量检测体系/测量管理体系的评审过程中,发现某些计量检定/校准人员以及计量管理人员对测量设备的“计量确认”与“检定”这两个专业用语分不清.以为测量设备的“计量确认”就是测量设备的“检定”。这两个专业用语在计量工作中究竟有何区别?企业在具体实施过程中应该如何应用?笔者现根据自己对这两个专业用语的理解作一些分析,与各位同行商榷。 相似文献

全国许多高校都设有检测中心、基础实验室或专业实验室以及后勤水电计量室,拥有大量的计量仪器和设备,它们担负着教学、实验、科研和后勤保障等许多工作,有些还通过了国家计量认证并向社会出具一些具有公正性质的检测报告。但拥有大量先进、高档仪器设备并担负着教学、科研和为社会服务任务的高等院校,大多数的计量仪器设备并没有按照计量法在各级法定计量检定机构进行检定或校准, 相似文献

从2002年第10期开始。《中国计量》杂志开辟《计量史话》专栏四年来,已刊登了60多篇计量史话文章,深受读者的欢迎和计量单位领导的重视,使得学习、研究、整理和收集计量史料、文物,弘扬我国古代计量科技成就的活动悄然升温。一些省市计量部门从收集和研究本地区古今的计量史料入手.建立、筹建和拟建“度量衡博物馆”、“计量博物馆”、“计量文史馆”。天津市质量技术监督局结合本市现存民国时期成套度量衡标准器,筹建了“天津市计量文史馆”,同时,拟题组织撰写一些我国计量发展史文章。现对涉及到我国计量发展史相关的“三量”、“四量”和“五量”之说的问题。提出我们的一孔之见,恳请专家及广大计量工作者指正赐教。 相似文献

Methodological problems of metrology are discussed. Metrology is viewed as an empirical scientific discipline in which the
basic notions are determined in an operational manner and ought to be verifiable. Relationship between metrology and theoretical
and experimental scientific branches is established. From the aspect of the methodology proposed herein, certain notions of
metrology are incorrectly defined and not verifiable.

Metrology, the science of measurement, has become an essential part of the technical infrastructure of industrialized countries. In cooperation with the BIPM, the national metrology institutes realize, maintain, and disseminate the units of the SI (Systeme International d'Unites), so making accurate measurements available to all users. The discovery of the macroscopic quantum effects provided the means of reproducing certain electrical units with an uncertainty considerably smaller than that of direct realization according to their SI definition. The reproduction of units in this way has become an important method of improving their maintenance and dissemination. The article highlights the advantages of such a method: it is general, it will certainly be extended to units other than electrical ones and it will generally improve the paths of traceability resulting in a better worldwide metrological network 相似文献

The system for Metrology in Chemistry in Germany is described. At the national standards level, a network of high-level chemistry
institutes coordinated by the national metrology institute, PTB, provides the primary references for chemical measurements.
A dissemination mechanism employs chemical calibration laboratories accredited within the framework of the German Calibration
Service (DKD). They act as “multipliers” between the national standards level and the user level by providing the user with
calibration means which are traceable to the SI via national standards. Traceability structures in clinical chemistry, electrochemistry,
elemental analysis and gas analysis are described 相似文献

随着国家"放管服"改革和事业单位改革进入深水区,作为计量行政部门依法设置的国家法定计量检定机构不得不面临调整。新的《计量法》仍未出台,国家法定计量检定机构在社会经济发展中的法律地位仍未明确。国际单位制的变革必将深刻改变计量发展,国家法定计量机构改革和发展何去何从,在这里笔者和大家一起探讨,特撰此文以飨读者。 相似文献

Regulatory measurements of particle mass concentration in air, such as PM10 and PM2.5, have been required in Europe for many years, but have been problematic as issues affecting the comparability of measurements, even when made by the reference method, have become apparent. The importance of airborne particulate matter for human health, and the complexity of the atmospheric processes affecting it, have led to many other parameters, such as particle number concentration, size distribution and composition being monitored, in some cases also as a regulatory requirement. Generally the metrological aspects have been covered by the monitoring network operators, with little involvement from National Metrology Institutes (NMIs). The United Kingdom (UK) National Physical Laboratory is unusual in being an NMI that also operates air quality networks on behalf of the government, directly involved in the full range of activities from fundamental metrology, standardisation of methods, and field operation. More recently, some of the measurement issues have started to be addressed by a group of NMIs within the European Metrology Research Programme. This paper outlines some of the key metrological problems in this area, and the current position in dealing with them from a UK and European perspective. 相似文献
