2019年世界计量日主题“单位制——本质的提升” 2019年世界计量日 5·20
2019年世界计量日宣传海报由中国香港标准和校准实验室设计(the Standards and Calibration Laboratory, Hong Kong, P.R. China)。 2019年世界计量日的主题是“单位制——本质的提升(The International System of Units - Fundamentally better)”。之所以选择这一主题，是因为2018年11月16日，计量大会做出了也许是对单位制(SI)自成立以来重要的一次修订。对包括利用量子现象的种种新式测量方法的研究，奠定了这一重大改变，这些新修订的内容将于2019年5月20日生效。现在，SI所基于的这组定义都是直接与物理定律一一相关，这一优势让我们可以欣然期待测量科学和技术的进一步提升，用户在未来多年的需求都能因此得以满足。 事实上，从更广泛的角度来看，计量学，作为一门测量科学，在科学发现和创新、工业制造和贸易，改善生活质量，以及保护环境等方面都发挥着核心作用。 世界计量日是为了纪念由17个国家的代表于1875年5月20日签署的《米制公约》而设立的年度庆祝活动。《米制公约》为测量科学及其在工业、商业和社会领域的应用中的合作确定了框架。《米制公约》的制定初衷就是在世界范围内保证测量的一致性，这一初目标在今天的重要性丝毫不亚于1875年。 原文如下： World Metrology Day - 20 May - The theme for World Metrology Day 2019 is The International System of Units - Fundamentally better. This theme was chosen because on 16 November 2018, the General Conference on Weights and Measures agreed perhaps one of the most significant revisions to the International System of Units (the SI) since its inception. Research into new measurement methods, including those using quantum phenomena, underpin the change, which comes into force on 20 May 2019. The SI is now based on a set of definitions each linked to the laws of physics and have the advantage of being able to embrace further improvements in measurement science and technology to meet the needs of future users for many years to come. Indeed more widely metrology, the science of measurement, plays a central role in scientific discovery and innovation, industrial manufacturing and international trade, in improving the quality of life and in protecting the global environment. World Metrology Day is an annual celebration of the signature of the Metre Convention on 20 May 1875 by representatives of seventeen nations. The Convention set the fr amework for global collaboration in the science of measurement and in its industrial, commercial and societal applications. The original aim of the Metre Convention - the world-wide uniformity of measurement - remains as important today as it was in 1875. The World Metrology Day project is realized jointly by the BIPM and the OIML. We hope that you enjoy this site and that your Country or Metrology Organization will join us and participate in this year's event. Warm regards, The WMD Team 2019年世界计量日主题“单位制——本质的提升” |
