<blockquote>
Within the four-particle cluster approximation, we obtain an equation
for the q-dependent deuteron pair correlation functions of DKDP and DADP
crystals to which external hydrostatic and uniaxial \sigma_3
pressure is applied. Their wavevector, temerature and pressure dependences
are studied. Expressions for the dielectric permittivities of
the strained crystals are derived. It is shown
that under the proper choice of theory parameters, the obtained results
agree well with the available experimental data.
