　　当我们在21世纪反思迅猛变化时，我们可能会说，“唯一不变的就是变化本身”。对于计量工作的需要，以及如何满足这种需求，之于任何人来说都毫无例外；而将一个稳定可靠和精准的测量系统所带来的便利应用于动态的世界无疑是一种挑战。

　　众多新技术的运用满足了许多社会需求，从本质上讲，这是通过稳定和准确的计量才得以实现的。无论是在一个高速运转的磁盘驱动器中，还是在电网中可再生能源的供应和需求变化方面，或是推动环境改善和提高航空航天工业的燃油效率方面，准确掌握动态量对应用高技术取得进展是至关重要的。动态数量还在现有工业中扮演越来越重要的角色，如火车及卡车的动态称重和对汽车轮胎与发动机的震动及影响的监测。

　　这类动态计量的运用带来了特别的挑战。在日常应用中，将高度准确的长期稳定标准同动态原位计量技术结合起来是比较困难的，其本身就需要伟大的创新。

　　想要让我们的计量能力适用于动态世界还需要其他措施。对于“2018再定义计划”来说，对国际单位制（SI）的未来需求将是一个关键驱动力。这种变化将确保更大的全球普遍性的测量系统会带来更多益处，并且在未来科学和技术革新中创造新的机遇。

　　我们需要动态的组织中处于动态的人们来化解动态世界中的计量问题。

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.
