　　當(dāng)我們?cè)?1世紀(jì)反思迅猛變化時(shí)，我們可能會(huì)說，“唯一不變的就是變化本身”。對(duì)于計(jì)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(gè)穩(wěn)定可靠和精準(zhǔn)的測量系統(tǒng)所帶來的便利應(yīng)用于動(dòng)態(tài)的世界無疑是一種挑戰(zhàn)。

　　眾多新技術(shù)的運(yùn)用滿足了許多社會(huì)需求，從本質(zhì)上講，這是通過穩(wěn)定和準(zhǔn)確的計(jì)量才得以實(shí)現(xiàn)的。無論是在一個(gè)高速運(yùn)轉(zhuǎn)的磁盤驅(qū)動(dòng)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(dòng)環(huán)境改善和提高航空航天工業(yè)的燃油效率方面，準(zhǔn)確掌握動(dòng)態(tài)量對(duì)應(yīng)用高技術(shù)取得進(jìn)展是至關(guān)重要的。動(dòng)態(tài)數(shù)量還在現(xiàn)有工業(yè)中扮演越來越重要的角色，如火車及卡車的動(dòng)態(tài)稱重和對(duì)汽車輪胎與發(fā)動(dòng)機(jī)的震動(dòng)及影響的監(jiān)測。

　　這類動(dòng)態(tài)計(jì)量的運(yùn)用帶來了特別的挑戰(zhàn)。在日常應(yīng)用中，將高度準(zhǔn)確的長期穩(wěn)定標(biāo)準(zhǔn)同動(dòng)態(tài)原位計(jì)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(jì)量能力適用于動(dòng)態(tài)世界還需要其他措施。對(duì)于“2018再定義計(jì)劃”來說，對(duì)國際單位制（SI）的未來需求將是一個(gè)關(guān)鍵驅(qū)動(dòng)力。這種變化將確保更大的全球普遍性的測量系統(tǒng)會(huì)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(jī)遇。

　　我們需要?jiǎng)討B(tài)的組織中處于動(dòng)態(tài)的人們來化解動(dòng)態(tài)世界中的計(jì)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.
