Al’manac of Modern Metrology № 4 (28) 2021

The running issue of the “Almanac of Modern Metrology” 4 (28) is the fourth issue this year. The foreword to this issue deals with the development of new high-precision methods and measuring instruments at VNIIFTRI.
The issue contains articles highlighting the young scientists’ contribution to metrology of such important metrological areas of measurements as time-frequency, coordinate-temporal, radio engi­neering, physicochemical, low-temperature and others. The results of the work were reported at the IX Scientific and Technical Conference “Metrology in the XXI century” and were approved by the leading experts of the Organizing Committee of this popular scientific and technical event. At the same time, taking into account the fact that individual authors have invited their research advisors to write and prepare the articles, this has significantly increased the level of published materials.
