The change of lattice parameters with time when up = 0.5 km/s. The definition of lattice parameters a, b, r corresponds to Fig. 9(a) and Fig. 10(b). Here a is the distance between atoms 1 and 2, b is the distance between atoms 1 and 3, c is the distance between atoms 3 and 5, d is the distance between atoms 1 and 5, and r is the ratio of c to d. The lattice parameters a and b are scaled.
