2021年5月20日是第22個“世界計量日”，國際法制計量組織和國際計量局發布了2021年世界計量日主題“Measurements for Health”及海報，該主題旨在讓人們認識到測量在守護我們每個人的平安健康中所發揮的重要作用。為配合“世界計量日”活動開展，市場監管總局將“世界計量日”中文主題正式確定為“測量守護健康”。 

　　“世界計量日”是由國際米制公約組織和國際法制計量組織為紀念1875年5月20日《米制公約》簽署而設立。1999年經國際計量大會投票表決，決定自2000年起，將米制公約簽署日（5月20日）作為“世界計量日”。

　　測量守護健康  

　　在全世界聚焦如何從新冠肺炎疫情的影響中快速有效地復蘇之際, 2021年世界計量日即將到來。 

　　2020年伊始，新冠病毒影響世界各地人民的速度之快和程度之烈，迫使各國政府迅速作出反應。在疫情剛剛蔓延之際，新的測量需求就大量涌現。首先是大范圍的病毒檢測，個人防護設備性能的檢測，其后的疫苗開發也依賴于對復雜蛋白和RNA分子的準確識別和測量。 

　　這些需求的規模巨大，使許多國家的優先事項發生改變。為應對病毒的挑戰，保護民眾健康, 政府重新聚焦現有科學能力，全球計量界也加入到了應對這些新的國家和全球挑戰的努力中，利用已擁有的測量科學方面的經驗來解決諸如以下的國家需求： 

　　·個人防護口罩檢測系統的建立； 

　　·醫院所需新型呼吸機系統的設計和檢測； 

　　·檢測樣品中病毒分子的識別和計數； 

　　·疫苗免疫效力的測量。 

　　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，使得上述工作成為可能。這些能力包括： 

　　·為具有測量功能的所有類別的醫療設備制定國際標準，包括自動血壓計、眼科儀器和醫用注射器等； 

　　·支持臨床實驗室檢測，確保醫用溫度計的測量與國際認可的溫標相符； 

　　·確保患者在X射線檢查中接受正確的輻射劑量； 

　　·為保證癌癥治療中準確的放射劑量提供基礎。 

　　我們選擇“測量守護健康”作為今年世界計量日的主題，是希望讓人們關注測量在守護人民健康方面所發揮的重要作用，尤其是在世界各國計量機構迅速將其經驗和能力轉向應對新的國家健康挑戰之時，它的到來恰逢其時。 

　　祝愿2021年世界計量日取得圓滿成功！期待得到各方世界計量日的宣傳海報和舉辦活動方面的更多信息。

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.
