Analytic calculation of the establishing of oscillations in an automatically biased parametric (subharmonic) oscillator
Vu An Fi and V.I. Medvedev
The secondary truncation technique is employed for obtaining approximate solutions of a system of truncated differential equations for a single-loop automatically biased parametric oscillator. Approximate analytic equations are obtained for describing the establishing of oscillations in a parametric oscillator with allowance for simultaneous action of three amplitude limiting mechanisms (without allowance for the response lag of the automatic biasing network). Some analytic calculations are compared with numerical calculations and with experimental results.

Yu.G. Pavlenko, A.S. Vshivtsev, and A.Kh. Mussa
The motion anc radiation of a charged particle in the field of a plane electromagnetic wave is investigated. The nature of the motion is found to depend on the initial conditions and on the magnitude of the wave intensity parameter.

On the limiting sensitivity of gravity-wave detectors
Yu.I. Vorontsov and F.Ya. Khalili
The limiting sensitivity of gravity-wave detectors with a capacity transducer is examined. Expressions are obtained for the transducer response to a sinusoidal signal and to fluctuations. Conditions for the detection of the regular signal on the background of fluctuations are examined and a new algorithm for signal extraction is suggested.

On the excitation of large-amplitude waves in electrodynamic structures (decelerating systems)
V.K. Grishin
The limiting fields generated by a magnetized beam in a decelerating system are estimated by the nonlinear kinetic equation technique. It is shown that large- amplitude waves can be attained only in systems with low phase velocity. The limiting values of the field potential and beam current are estimated.
