An important cause of sound radiation from a submarine in the low frequency range is fluctuating forces at the propeller. The forces are transmitted to the hull via the shaft and the fluid. Sound radiation occurs due to hull and propeller vibrations as well as dipole sound radiation caused by the op

Resonance Raman spectra of acetylene with excitation at 204 and 178 nm in the region of the 2-A ( ICI-' 'Z; in Dmh) and x+& '2: --t 'Au in Dmh) transitions exhibit very strong activity in both even and odd quanta of the $( v,) trans bending vibration. Enhancement of the two-quantum even overtone is
The motion of an auto:aomous mechanical system with one degree of freedom subject to small time-periodic perturbations and small dissipative forces in the vicinity of a stable position of equilibrium of the system is considered. It is assumed that resonance occurs in forced vibrations when the ratio
