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日是世界計量日，以紀(jì)念1875年《米制公約》簽署日。該公約為一致的測量系統(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)制造和貿(mào)易以及提高生活質(zhì)量和保護(hù)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年世界計量日的主題是“貿(mào)易計量” 。選擇該主題的目的是提高人們對計量在促進(jìn)公平貿(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。

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)，國家計量機(jī)構(gòu)通過在必要的復(fù)雜程度上開發(fā)和驗證新的計量技術(shù)，不斷推進(jìn)測量科學(xué)的發(fā)展。國家計量機(jī)構(gòu)參與計量局（BIPM）協(xié)調(diào)的比對，以確保測量結(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.
法定計量組織（OIML）制定了建議，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)受管制測量儀器的接受和貿(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.
這些計量系統(tǒng)為計量準(zhǔn)確提供了必要的保證和信心，為今天的貿(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.
世界計量日表彰和慶祝所有在政府間和國家計量組織和研究所工作的人全年所作的貢獻(xiàn)。
