2019年世界計量日主題:國際單位制(SI)—根本性飛躍

國際單位制(SI)—根本性飛躍

 

為紀念1875年《米制公約》的簽署,每年的5月20日被設立為世界計量日。《米制公約》為全球一致的測量系統奠定了基礎,支撐了科學發現和創新、工業制造和國際貿易,以及民生改善和全球環境保護。

2019年世界計量日的主題是“國際單位制—根本性飛躍”。之所以選擇這個主題,是因為2018年11月16日國際計量大會通過了有關修訂國際單位制(SI)的決議——這有可能是SI自建立以來最重大的修訂之一。這一修訂是在對測量新方法,包括對利用量子現象的測量方法的研究基礎上實現的。現在,SI建立在與物理定律直接關聯的一系列定義之上,其優勢是可以隨時迎接測量科學與技術的新發展,滿足未來用戶的長遠需求。

放眼世界,各國國家計量院都在通過研究和驗證不同成熟度的新型測量技術,持續推動測量科學進步。各國計量院通過參與由國際計量局(BIPM)組織的比對來確保全球范圍測量結果的可靠性。BIPM還為成員國提供了一個共同應對測量新挑戰的交流平臺。國際法制計量組織(OIML)通過制定國際建議,實現多個領域相關要求的全球一致性和協調性。

“世界計量日”代表全人類肯定和頌揚所有工作在政府間組織和各國計量機構的計量工作者一年以來所做貢獻。

 

關于“世界計量日”

世界計量日是一年一度的活動。這一天,80多個國家舉辦慶祝活動,宣傳計量對我們日常生活的影響。

之所以選擇這個日子,是為了紀念《米制公約》在1875年5月20日簽署,這也標志著國際計量合作的正式開始。每年的世界計量日慶祝活動由米制公約組織和國際法制計量組織聯合組織舉辦,各國計量機構參與其中。

國際計量界致力于確保全球范圍內準確測量活動的開展,通過每年世界計量日海報及網站的宣傳來增強公眾對計量的認識。以往世界計量日的主題包括計量與全球能源挑戰、計量與安全、計量與創新,以及體育中的計量、環境中的計量、醫療和貿易中的計量等。

 

關于米制公約

1875年簽署的《米制公約》創立了BIPM,正式開啟了國際計量合作。《米制公約》為各個測量領域量值的全球統一奠定了基礎。歷史上,計量主要關注并支持工業和貿易領域。但是,氣候變化、健康、能源等21世紀人類亟需解決的重大挑戰領域,也成為了計量關注的焦點。BIPM對選取的部分物理、化學量值開展最高層次的科學研究。BIPM將各國的國家計量院聯系起來,是世界計量網絡的核心與中樞。各國的國家計量院通過可溯源至SI的溯源鏈向各認證認可實驗室和工業界傳遞量值,從而保證各國測量量值對SI的溯源性。

 

關于國際法制計量組織

1955年,國際法制計量組織作為一個政府間締約組織成立。國際法制計量局(BIML)是該組織的秘書處和總部。OIML和BIML旨在促進全球法制計量規則的協調一致。自成立以來,OIML的首要目的是建立全球范圍內適用的技術框架,以協調各國國家計量部門或相關組織采用的計量法規和計量管理的一致性。

 

The International System of Units

Fundamentally better

Release: 

May 20 is World Metrology Day, commemorating the anniversary of the signing of the Metre Convention in 1875. This treaty provides the basis for a coherent measurement system worldwide that underpins scientific discovery and innovation, industrial manufacturing and international trade, as well as the improvement of the quality of life and the protection of the global environment. 

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. 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.

Across the world, national metrology institutes continually advance measurement science by developing and validating new measurement techniques at whatever level of sophistication is needed. The national metrology institutes participate in comparisons coordinated by the Bureau International des Poids et Mesures(BIPM) to ensure the reliability of measurement results worldwide. The BIPM also provides a forum for its Member States to address new measurement challenges. The International Organization of Legal Metrology (OIML) develops International Recommendations, the aim of which is to align and harmonize requirements worldwide in many fields.

World Metrology Day recognizes and celebrates the contribution of all the people that work in intergovernmental and national organizations throughout the year on behalf of all.

Notes for Editors:

World Metrology Day is an annual event during which more than 80 countries celebrate the impact of measurement on our daily lives.

This date was chosen in recognition of the signing of the Metre Convention on 20 May 1875, the beginning of formal international collaboration in metrology. Each year World Metrology Day is organized and celebrated jointly by the International Bureau of Weights and Measures (BIPM) and the International Organization of Legal Metrology (OIML) with the participation of the national organizations responsible for metrology.

The international metrology community which works to ensure that accurate measurements can be made across the world endeavors to raise awareness each World Metrology Day through a poster campaign and web site. Previous themes have included topics such as measurements for the global energy challenge, for safety, for innovation, and measurements in sport, the environment, medicine and trade.

 

About the BIPM

The signing of the Metre Convention in 1875 created the BIPM and for the first time formalized international cooperation in metrology. The Convention established the International Bureau of Weights and Measures and laid the foundations for worldwide uniformity of measurement in all aspects of our endeavors, historically focusing on and assisting industry and trade, but today just as vital as we tackle the grand challenges of the 21st Century such as climate change, health, and energy. The BIPM undertakes scientific work at the highest level on a selected set of physical and chemical quantities. The BIPM is the hub of a worldwide network of national metrology institutes (NMIs) which continue to realize and disseminate the chain of traceability to the SI into national accredited laboratories and industry.

 

About the OIML

In 1955 the International Organization of Legal Metrology (OIML) was established as an Intergovernmental Treaty Organization in order to promote the global harmonization of legal metrology procedures with the Bureau International de Métrologie Légale (BIML) as the Secretariat and Headquarters of the OIML. Since that time, the OIML has developed a worldwide technical structure whose primary aim is to harmonize the regulations and metrological controls applied by the national metrological services, or related organizations.
