摘要：
The adiabatic elastic constants C-11, C-12 and C-44 have been evaluated for crystalline KCl as a function of pressure at room temperature. The evaluation is based on a two-body central potential of the form A(1)R(-9) + A(2)R(-6) +/- A(3)R(-1) and the normal mode frequencies obtained from local dynamics of two particles allowed to oscillate in a static potential field due to all the rest of particles assumed at rest in their mean positions. The pressure dependence of these principal adiabatic elastic constants is examined in comparison with available experimental data, and a reasonable agreement is observed.
