Interband Optical Transitions,s of the macroscopic theory of additional light waves, in which Maxwell’s boundary conditions are complemented by the boundary conditions for an excitonic contribution to the dielectric polarization of the medium (the so-called ..

Intraband Transitions, mass in a superlattice at the miniband bottom, analyze how the choice of the boundary conditions for the envelopes at the interfaces affects these masses, and discuss the nonparabolicity of the miniband spectrum.

On the premise of analyzing and studying the stratigraphic sedimentary environment in the mining area in detail, it is of great significance for the realization of "coal water" dual resource mining in the mining area to divide the types of roof water disaster in the mining ar

Eougenious L. Ivchenko,Grigory Pikus be applied to the underside. Differential deflection between adjacent units is prevented by running a cement mortar grout into dovetail grooves formed by rebates cast in the edges of adjacent units. A splay on the lower arrises reduces the risk of damage during handling and masks slight differences
