摘要：
On the basis of digital computer simulation of the operation of a wave channel under dynamic conditions, regularities of interaction of an ultrasonic measuring signal with primary physical fields rapidly changing in time and space have been revealed. It has been show that the determination of space and time structures of physical fields with specific sizes of inhomogeneities, which are considerably less than the measurement base and transit time of an ultrasonic signal through the field, is possible. Dynamic measurement errors are discussed.
