The fourth issue of the Al’manac presents the latest results from metrological studies in such areas as underwater acoustic and time and frequency measurements. A special focus is given to methods and devices for metrological support for GLONASS. Undoubtedly of interest is search and new solutions to metrological problems, particularly those of instrument calibration. Considerable space is devoted to national calibration and measurement capabilities in the domain of time and frequency measurements. One section, which is becoming a regular feature of the Al’manac, is dedicated to new priorities in metrology, in particular those related to the use of ultrasound in medicine and human environment monitoring.
The Al’manac introduces a new book on metrolgy, in the field of metrological support for neutron measurements at Russian nuclear-physics facilities.
