2021年5月20日是第22個“世界計（jì）量日”，國（guó）際法製計量（liàng）組織和（hé）國際計量局發布了2021年世界計量日主題“Measurements for Health”及海報，該主題（tí）旨在讓人們認識到測量在守護我們每個人的（de）平安健康中所發揮（huī）的重要作用。為配合“世界計量日（rì）”活動開展，市場監管總局將“世界計量日”中文主題正式確（què）定為“測量守護健（jiàn）康”。 

　　“世界（jiè）計（jì）量日（rì）”是由國際米製公約組織和國際法製計量組織為紀念1875年5月20日《米製公約》簽署而（ér）設立。1999年經國際計量大（dà）會投票（piào）表決，決定自2000年起，將米製（zhì）公約簽署日（5月20日）作（zuò）為“世界（jiè）計量日”。

　　測量守護健康  

　　在全（quán）世界聚焦如何從新冠肺炎疫情的影響中快速（sù）有效地複蘇之際, 2021年世界計量日即（jí）將到來。 

　　2020年伊始，新冠病毒影響世界各地人（rén）民的速度之快和程度之烈（liè），迫使各國政府迅速作出反應。在疫情剛剛蔓（màn）延之際，新的測量需求就大量湧現。首先是大範圍的病毒檢測，個人防護設備性能的檢測，其（qí）後的疫苗開發也依賴於對複雜蛋白和RNA分（fèn）子的準確識別和測量。 

　　這些需求的規模巨大，使許多國（guó）家的優先事（shì）項發（fā）生改變。為應對病（bìng）毒的挑戰，保護民眾健康, 政府重新聚焦現有科學能力，全球計量界也加入（rù）到了應（yīng）對這些新的國家和全（quán）球挑戰的努力中，利用已擁（yōng）有的測（cè）量科（kē）學方麵的經驗來解決諸如以下的國家需求： 

　　·個人防護口（kǒu）罩檢測係統的建立； 

　　·醫院所需新型呼吸機係統的設（shè）計（jì）和檢測； 

　　·檢測樣品中病毒分子的識別和計數； 

　　·疫（yì）苗免疫效力的測（cè）量。 

　　計量界已建立了支撐保護和促進健康所需要的各種測量的技術能力，使得上述（shù）工作成為可能。這些能力（lì）包括（kuò）： 

　　·為（wéi）具有測量功能的所有類（lèi）別的醫療設備製定國際標準，包括自動血（xuè）壓計、眼科（kē）儀器和醫用注（zhù）射器等； 

　　·支持臨床實驗室檢測，確保醫用（yòng）溫度計的測（cè）量與國際（jì）認可的溫標相符； 

　　·確保患者在X射線檢查中接受正確的輻射劑量； 

　　·為保證癌症治療中準確的放射劑量提供基礎。 

　　我們選擇“測量守護（hù）健康”作為今年世界計量日的主（zhǔ）題，是希（xī）望讓（ràng）人們關注測量在守（shǒu）護人民（mín）健康方麵所發揮（huī）的重要作用，尤其是在世（shì）界各國計量機構迅速將（jiāng）其經驗和能（néng）力轉向應對新的國家健康挑戰之時，它（tā）的到來恰逢其時。 

　　祝願2021年世界計量日取得圓滿成功！期待得到各（gè）方世界計量日的宣傳海報和舉辦活動方麵的更多信息。

Measurement for Health

World Metrology Day in 2021 comes at a time when the world is focussed on making a quick and effective recovery from the impact of the COVID-19 pandemic.

The speed and severity with which the virus impacted people around the world at the beginning of 2020 forced governments to respond rapidly. Right from the beginning, new measurement requirements emerged, starting with the need for large-scale testing for the presence of the virus and the performance of personal protective equipment. Subsequently, the development of vaccines has depended on accurate identification and measurement of complex protein and RNA molecules.

The enormous scale of these requirements has changed national priorities globally; governments have re-focussed established science capabilities to meet the challenge of protecting their populations from the impact of the virus. The metrology community around the globe has been involved with these new national and global challenges, and has used its established experience of measurement science to address national needs such as by:

• setting up systems to test masks needed for personal protection,

• contributing to the design and testing of new ventilator systems needed in hospitals,

• identifying and counting virus molecules in test samples, and

• measuring the efficacy of vaccine doses.

  
  

This has been possible because of established technical capabilities to support many of the measurements needed to protect and improve health. These include:

• developing international standards for all types of medical devices with a measuring function, including automated blood-pressure instruments, ophthalmic instruments and medical syringes,

• underpinning clinical laboratory testing by ensuring that measurements made by medical thermometers are in line with the internationally recognised temperature scale,

• ensuring that patients experience the correct dose of X-rays during diagnostic procedures, and

• providing the basis for accurate therapeutic doses of radiation in the treatment of cancer.

  
  

We chose the theme “Measurement for Health” for World Metrology Day this year to draw attention to the importance of measurement to support the protection of health. It comes at a time when the experience and capabilities invested in metrology organisations around the world have been turned at short notice to address new national health challenges.

We wish you a very successful World Metrology Day 2021 and look forward to receiving your posters and details of any events you are holding.
