摘要

在对“自然单位”[1]的有用介绍中，作者将自然单位与写作时(2016年)存在的SI进行了对比。国际单位制在b[1]中被描述为“严重依赖于精确测量标准原型、物体或系统来定义物理单位”的系统。特别是，国际单位制确实依赖于一个标准原型，称为国际千克原型。这个独特物体的质量定义为1kg。相比之下，“自然单位”，顾名思义，完全是根据用来描述自然世界的选定常数来定义的。不同的自然单位制是基于这些常数的不同选择。

Fundamentals of Measurement: The Revised SI Compared to Natural Systems of Units

In a useful introduction to “natural units” [1], the author contrasted natural units to the SI as it existed at the time of writing (2016). The SI was characterized in [1] as a system that “relies heavily on precision measurements of standard prototypes, objects or systems that define a physical unit.” In particular, the SI indeed relied on one standard prototype, called the International Prototype of the Kilogram. The mass of this unique object defined 1 kg. By contrast, “natural units,” as the name implies, are completely defined in terms of selected constants used to describe the natural world. Different systems of natural units are based on different selections of these constants.

期刊介绍： IEEE Instrumentation & Measurement Magazine is a bimonthly publication. It publishes in February, April, June, August, October, and December of each year. The magazine covers a wide variety of topics in instrumentation, measurement, and systems that measure or instrument equipment or other systems. The magazine has the goal of providing readable introductions and overviews of technology in instrumentation and measurement to a wide engineering audience. It does this through articles, tutorials, columns, and departments. Its goal is to cross disciplines to encourage further research and development in instrumentation and measurement.
