Abstract
A mechanical model of diatomic crystal lattice with force interaction between atoms and angular interaction between bonds taken into account is proposed. Some relations between the macroscopic moduli of elasticity and the microparameters of the longitudinal rigidity of interatomic bonds and of the angular interaction rigidity are obtained for crystals with diamond lattice. Comparison with experimental data and with other theories describing similar lattices is conducted by using two constants at the microlevel.
