國際計量局（BIPM）局長馬丁.米爾頓

　　當我們在21世紀反思迅猛變化時，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，之于任何人來說都毫無例外；而將一個穩定可靠和精準的測量系統所帶來的便利應用于動態的世界無疑是一種挑戰。

　　眾多新技術的運用滿足了許多社會需求，從本質上講，這是通過穩定和準確的計量才得以實現的。無論是在一個高速運轉的磁盤驅動器中，還是在電網中可再生能源的供應和需求變化方面，或是推動環境改善和提高航空航天工業的燃油效率方面，準確掌握動態量對應用高技術取得進展是至關重要的。動態數量還在現有工業中扮演越來越重要的角色，如火車及卡車的動態稱重和對汽車輪胎與發動機的震動及影響的監測。

　　這類動態計量的運用帶來了特別的挑戰。在日常應用中，將高度準確的長期穩定標準同動態原位計量技術結合起來是比較困難的，其本身就需要偉大的創新。

　　想要讓我們的計量能力適用于動態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鍵驅動力。這種變化將確保更大的全球普遍性的測量系統會帶來更多益處，并且在未來科學和技術革新中創造新的機遇。

　　我們需要動態的組織中處于動態的人們來化解動態世界中的計量問題。

Measurements in a dynamic world

When we reflect on the rapid pace of change in the 21st century, we may say that “the only thing that is constant is change itself”. The needs for metrology, and how these needs are met, are no exceptions; it is a challenge to bring the benefits of a stable and accurate measurement system to a dynamic world.

Many of the needs of society are met by new technologies, and it is essential that stable and accurate measurements are available to underpin them.

The accurate knowledge of dynamic quantities is pivotal to progress in high technology whether it is the high-speed movements in a disk drive, the variations in supply and demand from renewable energy sources on electricity grids, or the drive for environmental improvement and fuel efficiency in the aerospace industry. Dynamic quantities also play an increasing role in established industries, such as the dynamic weighing of trains and trucks, and the monitoring of vibration and impact arising from the tyres and engines of cars.

These applications of dynamic measurement bring particular challenges. Linking highly accurate long-term stable standards to dynamic in situ measurements in everyday applications is difficult and itself requires great innovation.

Adapting our measurement capabilities to a dynamic world requires other steps too. The need to ‘future proof’ the International System of Units (the SI) is one of the key drivers for the redefinition planned for 2018. The changes will ensure the benefits of greater universality of the world’s measurement system, and open new opportunities for scientific and technological advances in the future.

We all need dynamic people in dynamic organisations to address the challenges of measurement in a dynamic world.
