摘要
With the help of the decline method, a computer-aided analysis program of Christofell equation is described which makes it possible to calculate elastic and viscous constants of crystals precisely and easily. The elastic constants of LiNbO3 and Bi12 GeO20 crystals are calculated with an Apple - II computer and the Fortran program suggested; the calculated data are compared with the values achieved by others.
