- Аннотация: Assuming a highly deterministic pulsar's orbital motion in a close binary system, we have studied the possibility of using the orbital rotation period for establishing a new astronomical scale of the ephemeris dynamical time, which would allow the determination with high accuracy (10^-12-10^-15) of time intervals on long time scales of the order of several tens of years. This is necessary, in particular, for searching for ultra-low-frequency stochastic background of relict gravitational waves in the frequency range 10^-9-10^-12 Hz and for studying the limiting possibilities of testing alternative theories of gravity based on observations of binary pul- sars. A theoretical analysis is done of the actually attainable stability of such a scale in the presence of stochastic fluctuations of pulsar pulse arrival times, which represent a mixture of `white' and `red' noise with a power-law dependence of the noise intensity on the Fourier frequency f^-s for s = 1, 2, ..., 6. It is shown that the dynamical timescale realized in the pulsar's orbital motion proves to be more stable on long time intervals than the kinematical timescale based on the pulsar's rotation.
