A description of the vertical structure and the phase speed of long linear internal waves c can be found (in the Boussinesq approximation) from the following Sturm-Liouville problem:

On the other hand, the wavelength can also be 'estimated' from the phase speed [c.sub.p] of the same wave if we assume that the short wave satisfies the linear dispersion relation

where A is the area of impact, K is an empirical constant between 3 and 10, [rho] is the water density and C is the wave phase speed. For the southeast arm of the swastika this is

Figure 2 infers that the phase speed of both (III and IV) modes including and excluding QE increases with increasing carrier drift in terms of [E.sub.0].

Thus, if there exist coastal trapped waves, their wavelength, period and other parameters like phase speed are determined by dispersion relations (7) and (8).

A pair of hydrophones or transducers is used to transmit and receive a series of short monochromatic bursts of varying frequencies from which the attenuation and phase speed in the bubbly liquid are determined.

Structure change in the process of a pulling should obviously lead to some mismatch of phase speeds of waves interacting in PPLN, to compensation of the induced wave unbalancing (at the constant period of a domain grid), and as a result of temperature influence to the leveling of own crystal matrix absorption.
