摘要
质量是国际单位制的基本物理量之一,质量测量的准确度提高会为很多重要物理量的测量提供更准确的溯源。文中论述了空气中质量测量过程中的基本原理,并通过对折算质量差值的公式推导,分析了在测量过程中的重要影响量,对于提高质量测量的准确度有着重要意义。
Quality is one of the basic physical quantities of the international system of units, the quality measurement accuracy increase will provide many important physical quantity measurement more accurate traceability. This paper discusses the basic principle in the process of quality measurement in the air, and through to the reduced mass difference formula derivation, analysis the important influence in the process of measurement, to improve the accuracy of measurement quality has important significance.
