QUANTUM STANDARD FOR UNITS OF LENGTH, TIME, MASS AND FUNDAMENTAL PHYSICAL CONSTANTS

摘要

Contemporary methods are considered for storage and reproduction of the dimensions of basic SI units, i.e., length, time, and mass. The main trends are discussed for improving these methods in order to reduce reproduction errors for the dimensions of units. The importance of using results of theoretical calculations for microprocess characteristics and precise values for a number of fundamental physical constants is noted.
