国家标准局最近发布了包括GB 3102.0《物理化学和分子物理学的量和单位》在内的15个基础国家标准,并规定从今年7月1日起实施。为了配合在化学界宣传贯彻这套标准,特别是GB 3102.8,我们编写了这个有关量和单位的讲座,供参考。在第一讲中,我们将对量的基本概念、量和单位之间的关系和一贯单位制作扼要的讨论,对标准中涉及到的一些量的有关 The National Bureau of Standards recently released 15 basic national standards including GB 3102.0 “Quantum and Unit of Physical Chemistry and Molecular Physics”, which will be implemented from July 1 this year. In order to cooperate in the chemical industry propaganda and implementation of this set of standards, especially GB 3102.8, we have prepared this lecture on the amount and unit for reference. In the first lecture, we will make a brief discussion on the basic concept of quantity, the relationship between quantity and unit, and consistent units.
