鑄鐵砝碼,鑄鐵砝碼價格|分享計量日紀(jì)念發(fā)展

        為紀(jì)念1875年《米制公約》的簽署，每年的5月20日被設(shè)立為計量日?！睹字乒s》為?一致的測量系統(tǒng)奠定了基礎(chǔ)，支撐了發(fā)現(xiàn)和創(chuàng)新、工業(yè)和貿(mào)易，以及民生改善和?環(huán)境保護(hù)。

        2019年計量日的主題是“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日計量大會通過了有關(guān)修訂單位制（SI）的決議——這有可能是SI自建立以來重大的修訂之一。這一修訂是在對測量新方法，包括對利用量子現(xiàn)象的測量方法的研究基礎(chǔ)上實現(xiàn)的?，F(xiàn)在，SI建立在與物理定律直接關(guān)聯(lián)的一系列定義之上，其優(yōu)勢是可以隨時迎接測量與技術(shù)的新發(fā)展，滿足未來用戶的長遠(yuǎn)需求。

        放眼，各國都在通過研究和驗證不同成熟度的新型測量技術(shù)，持續(xù)推動測量進(jìn)步。各國通過參與由（BM）組織的比對來確保?范圍測量結(jié)果的性。BM還為成員國提供了一個共同應(yīng)對測量新挑戰(zhàn)的交流平臺。法制計量組織（）通過制定建議，實現(xiàn)多個領(lǐng)域相關(guān)要求的?一致性和協(xié)調(diào)性。

      “計量日”代表*和頌揚(yáng)所有工作在間組織和各國計量機(jī)構(gòu)的計量工作者一年以來所做貢獻(xiàn)。

關(guān)于“計量日”

        計量日是一年一度的活動。這，80多個舉辦慶?；顒樱麄饔嬃繉ξ覀?nèi)粘Ｉ畹挠绊憽?/span>

       之所以選擇這個日子，是為了紀(jì)念《米制公約》在1875年5月20日簽署，這也標(biāo)志著計量合作的正式開始。每年的計量日慶?；顒佑擅字乒s組織和法制計量組織聯(lián)合組織舉辦，各國計量機(jī)構(gòu)參與其中。

       計量界致力于確保?范圍內(nèi)準(zhǔn)確測量活動的開展，通過每年計量日海報及網(wǎng)站的宣傳來增強(qiáng)公眾對計量的認(rèn)識。以往計量日的主題包括計量與?能源挑戰(zhàn)、計量與安全、計量與創(chuàng)新，以及體育中的計量、環(huán)境中的計量、和貿(mào)易中的計量等。

關(guān)于米制公約

       1875年簽署的《米制公約》創(chuàng)立了BM，正式開啟了計量合作。《米制公約》為各個測量領(lǐng)域量值的?統(tǒng)一奠定了基礎(chǔ)。歷*，計量主要關(guān)注并支持工業(yè)和貿(mào)易領(lǐng)域。但是，氣候變化、健康、能源等21世紀(jì)人類亟需解決的重大挑戰(zhàn)領(lǐng)域，也成為了計量關(guān)注的焦點。BM對選取的部分物理、化學(xué)量值開展高層次的研究。BM將各國的聯(lián)系起來，是計量網(wǎng)絡(luò)的與中樞。各國的通過可溯源SI的溯源鏈向各認(rèn)可實驗室和工業(yè)界傳遞量值，從而各國測量量值對SI的溯源性。

關(guān)于法制計量組織

        1955年，法制計量組織作為一個間締約組織成立。法制（BIML）是該組織的秘書處和總部。和BIML旨在促進(jìn)?法制計量規(guī)則的協(xié)調(diào)一致。自成立以來，的首要目的是建立?范圍內(nèi)適用的技術(shù)框架，以協(xié)調(diào)各國計量部門或相關(guān)組織采用的計量法規(guī)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(BM) to ensure the reliability of measurement results worldwide. The BM also provides a forum for its Member States to address new measurement challenges. The International Organization of Legal Metrology () 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 theInternational Bureau of Weights and Measures (BM) and the International Organization of Legal Metrology () 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 BM

The signing of the Metre Convention in 1875 created the BM 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 BM undertakes scientific work at the highest level on a selected set of physical and chemical quantities. The BM 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

In 1955 the International Organization of Legal Metrology () 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 . Since that time, the 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.
