當我們回顧第二十一個世紀的快速變化時,我們可能會說,“唯一不變的就是變化本身”。對于計量工作的需要,以及如何滿足這種需求,對于任何人來說都毫無例外。而將一個穩(wěn)定可靠和精準的測量系統(tǒng)所帶來的便利應(yīng)用于動態(tài)的世界無疑是一種挑戰(zhàn)。
眾多新技術(shù)的運用滿足了許多社會需求,從本質(zhì)上講,這是通過穩(wěn)定和準確的計量才得以實現(xiàn)的。無論是在一個高速運轉(zhuǎn)的磁盤驅(qū)動器中,還是在電 網(wǎng)中可再生能源的供應(yīng)和需求變化方面,或是推動環(huán)境改善和提高航空航天工業(yè)的燃油效率方面,準確掌握動態(tài)量對應(yīng)用高技術(shù)取得進展是至關(guān)重要的。動態(tài)數(shù)量也 在現(xiàn)有工業(yè)中扮演越來越重要的角色,如火車和卡車的動態(tài)稱重和對汽車輪胎與發(fā)動機的震動與影響的監(jiān)測。
這類動態(tài)計量的運用帶來了特別的挑戰(zhàn)。在日常應(yīng)用中,將高度準確的、長期穩(wěn)定的標準同動態(tài)原位計量技術(shù)結(jié)合起來是比較困難的,其本身就需要偉大的創(chuàng)新。
想要讓我們的計量能力適用于動態(tài)的世界還需要其他措施。對于“2018再定義計劃”來說,對國際單位制(SI)的未來需求將是一個關(guān)鍵驅(qū)動力。這種變化將確保更大的全球普遍性的測量系統(tǒng)會帶來更多益處,并且在未來科學(xué)和技術(shù)革新中創(chuàng)造新的機遇。
我們需要動態(tài)的組織中處于動態(tài)的人們來化解動態(tài)世界中的計量問題。
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 chosen for 2016 is Measurements in a dynamic world. This reflects both the challenge of accurately measuring dynamic quantities, for example the pressures in a combustion chamber, and the rapid pace of change in measurement science today.
Across the world, national metrology institutes continually advance measurement science by developing and validating new measurement techniques at whatever level of sophistication is needed. They also participate in comparisons coordinated by the Bureau International des Poids et Mesures (BIPM) to ensure the reliability of measurement results worldwide. The BIPM also provides a forum for its Member States to address new measurement challenges.
Many measuring instruments such as continuous weighing machines, radars for measuring vehicle speed, etc. that are used to measure objects in motion are subject to legal requirements or to regulatory control. Additionally, new technologies constantly change both the way in which these instruments make measurements and the methods needed for their control – “smart” meters for energy or water are one example. The International Organization of Legal Metrology (OIML) develops International Recommendations, the aim of which is to align and harmonize requirements for these types of instruments worldwide.
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.

日前,國際計量局正式公布2016年世界計量日主題“Measurements in a dynamic world”,并附上宣傳海報。
宣傳海報由俄羅斯國家計量研究所VNIIMS提供,縱觀整個海報,上端標明了2016年世界計量日的主題---動態(tài)世界中的計量,下端為計量日的相關(guān)信 息,海報主體則用了衛(wèi)星、運載火箭、航空飛機、高鐵等正在運動的的高科技元素。位于海報中心部分的航空飛機上印制著“ZEHST”字樣;“ZEHST”全 稱“Zero Emission Hypersonic Transportation”,意為零排放超音速飛機,是全球正在致力研發(fā)的新型高速客機。
眾所周知,世界是“運動”的、科技也是“運動”的,結(jié)合海報的內(nèi)容與主題“動態(tài)世界中的計量”,不難看出,2016年計量日主題反映的是動態(tài)數(shù)據(jù)的準確測量,及須適應(yīng)如今科技快速發(fā)展的新型計量模式。
計量是支撐社會、經(jīng)濟和科技發(fā)展的重要基礎(chǔ)。自1875年簽訂《米制公約》以來,科學(xué)的計量方法和準確的測量數(shù)據(jù)給世界科技帶來了日新月異的發(fā)展,而科技的發(fā)展同樣也帶來了不斷革新的測量需求,二者相輔相成,缺一不可。
現(xiàn)如今,在第四次工業(yè)革命的大時代背景下,動態(tài)數(shù)據(jù)的準確測量和新型的計量方法尤為重要。如工頻到變頻、傳統(tǒng)材料到新型材料、常規(guī)能源到新能源等技術(shù)不斷革新著世界,那么捕捉實時數(shù)據(jù),依靠傳統(tǒng)的測量方式難以滿足,世界亟需新方法來適應(yīng)新時代。
世界計量日作為推廣計量的世界性紀念日,而計量作為加速科技發(fā)展的重要依據(jù),推廣鼓勵適用新時代的計量方式也自然成了其神圣使命,而此次計量日主題則恰恰反映出國際計量局所作的努力及愿望。
