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 worldwide coherent measurement system 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.
5月20日是世界計(jì)量日，以紀(jì)念1875年《米制公約》簽署日。該公約為全球一致的測(cè)量系統(tǒng)奠定了基礎(chǔ)，該系統(tǒng)是科學(xué)發(fā)現(xiàn)和創(chuàng)新、工業(yè)制造和國(guó)際貿(mào)易以及提高生活質(zhì)量和保護(hù)全球環(huán)境的基礎(chǔ)。

The theme for World Metrology Day 2020 is Measurements for global trade. This theme was chosen to create awareness of the important role measurement plays in facilitating fair global trade, ensuring products meet standards and regulations, and satisfying customer quality expectations.
2020年世界計(jì)量日的主題是“全球貿(mào)易計(jì)量” 。選擇該主題的目的是提高人們對(duì)計(jì)量在促進(jìn)公平全球貿(mào)易，確保產(chǎn)品符合標(biāo)準(zhǔn)和法規(guī)以及滿足客戶質(zhì)量期望方面的重要作用的認(rèn)識(shí)。

Across the world, national metrology institutes continually advance measurement science by developing and validating new measurement techniques at the necessary level of sophistication. The national metrology institutes participate in measurement comparisons coordinated by the Bureau International des Poids et Mesures (BIPM) to ensure the reliability of measurement results worldwide.
在世界范圍內(nèi)，國(guó)家計(jì)量機(jī)構(gòu)通過在必要的復(fù)雜程度上開發(fā)和驗(yàn)證新的計(jì)量技術(shù)，不斷推進(jìn)測(cè)量科學(xué)的發(fā)展。國(guó)家計(jì)量機(jī)構(gòu)參與國(guó)際計(jì)量局（BIPM）協(xié)調(diào)的國(guó)際比對(duì)，以確保全球測(cè)量結(jié)果的可靠性。

The International Organization of Legal Metrology (OIML) develops International Recommendations, which aim to align and harmonise requirements worldwide in many fields. The OIML also operates the OIML Certification System (OIML-CS) which facilitates international acceptance and global trade of regulated measuring instruments.
國(guó)際法定計(jì)量組織（OIML）制定了國(guó)際建議，旨在協(xié)調(diào)和統(tǒng)一世界范圍內(nèi)許多領(lǐng)域的要求。OIML還運(yùn)行OIML認(rèn)證系統(tǒng)（OIML-CS），該系統(tǒng)促進(jìn)受管制測(cè)量?jī)x器的國(guó)際接受和全球貿(mào)易。

These international metrology systems provide the necessary assurance and confidence that measurements are accurate, providing a sound basis for global trade today and helping us to prepare for the challenges of tomorrow.
這些國(guó)際計(jì)量系統(tǒng)為計(jì)量準(zhǔn)確提供了必要的保證和信心，為今天的全球貿(mào)易提供了良好的基礎(chǔ)，并幫助我們?yōu)槊魈斓奶魬?zhàn)做好準(zhǔn)備。

World Metrology Day recognises and celebrates the contribution of all the people that work in intergovernmental and national metrology organisations and institutes throughout the year.
世界計(jì)量日表彰和慶祝所有在政府間和國(guó)家計(jì)量組織和研究所工作的人全年所作的貢獻(xiàn)。
