Because the teaching methods of Chinese teaching in higher vocational colleges are improper and the problems in the teaching process cannot be found in time, the teaching effect is not good and there are many difficulties in the teaching process of teachers. According to actual needs, based on complex evolution and improved neural network algorithms, this paper builds a Chinese online teaching system in high vocational colleges. After communication with users and social research, the model function module is determined, and the system performance is improved through the mapping optimization model to eliminate data transmission problems in the system operation, and the realization process of the system function module is shown in the form of a diagram. In addition, this paper designs a control experiment to verify the performance of the model and uses the traditional algorithm model as a control to start the test teaching and uses statistical methods to compare the teaching effects. The research results show that the teaching system constructed in this paper has certain advantages over the traditional model.

The diversity of lexical functions in Bulgarian and Russian: an approach to compatible digital comparative lexicographyThis paper presents an approach to the creation of Russian-Bulgarian digital dictionary of collocations using the apparatus of lexical functions. The project is aimed not only at the high-quality translation and word sense disambiguation but also at the cross-linguistic analysis and at comparing the semantics and compatibility of the words in Slavic languages (here: Russian and Bulgarian) by means of digital lexicographical data. Another important application is computer-assisted language learning: Bulgarian data can be incorporated in the educational project being developed for Russian and English at the Institute for Information Transmission Problems of the Russian Academy of Sciences.

Let ϒ be a three-dimensional Lipschitz polyhedron, and assume that the matrix function μ is piecewise constant on a polyhedral partition of ϒ. Based on regularity results for solutions to two-dimensional anisotropic transmission problems near corner points we obtain conditions on μ and the intersection angles between interfaces and ∂ϒ ensuring that the operator -∇ · μ∇ maps the Sobolev space [Formula: see text] isomorphically onto W-1,q(ϒ) for some q > 3.
