METHOD OF MEASURING AIR-TIGHTNESS OF CLOSED JARS MADE OF DIELECTRIC MATERIAL

摘要

FIELD: measuring technique. ^ SUBSTANCE: when measuring air-tightness of close jars made of dielectric material, measurement of resonant frequency and frequency of beating of frequency-modulated oscillations is used followed by analytical conversion of mentioned characteristics which have information on air-tightness of closed jars. ^ EFFECT: reduced error of measurement. ^ 1 dwg
