Within the framework of the concepts of heterogeneous nucleation and wave growth of martensite the refinement of a technique of account of wave normals NW to expected habits planes are carried out. The technique allows to connect orientations of NW with definite areas of nucleation of crystals in an elastic field of defects. The specific results are for system Cu-Zn. As separate rectilinear dislocations with lines [l 1 71 and dislocation loops basic elements of which are pieces of these lines are considered here as probable centers of nucleation. It is shown, that the spectrum of NW can be coordinated with experimentally observable space distribution 8f normals N, in a vicinity of a pole[2 11 121. The similar coordination opens additional opportunities to reconstruct a stage of martensle nucleation from morphological attributes and to transform a distribution of habits in the informative parameter.

— The article analyzes the level of import dependence of Russian industry in relation to the supply of intermediate consumption products from China and in general from all countries of the world. The study was carried out during the period of the increasing spread of coronavirus infection in order to determine the industries that are potentially the most vulnerable to possible disruption of foreign trade. The information base for calculations is the official data on the volume and structure of Russia’s foreign trade and the input–output tables of the WIOD. As a result of calculations using several alternative models, it was found that Russian industry, even with significant integration into the world production chains, remains sufficiently resistant to local supply shocks. The analysis of import dependence in terms of imported raw materials and components can be used in the study of any shocks in foreign trade, it makes it possible to more accurately assess the effects of trade agreements or sanctions, as well as the effect of the devaluation of the national currency.
