“…Therefore, the translation objects of business English are diversified, and different professional fields have different requirements for the language system of translation. If you want to do a good job in English translation, you should not only have the comprehensive ability of reading and understanding, but also necessarily explore the regular characteristics of the translation of various words, so as to provide valuable references for translation [ 1 ]. Common words in the context of business English will be given new meanings.…”

The theory of linguistic environment parameters has an important influence on English translation. Based on this parameter, it can provide guidance for the semantic generation of English translation. In the actual translation process, people’s native language thinking amount accounts for 56.2% and English thinking amount accounts for 43.8%. Translation is mostly used in texts, accounting for 40.6%, and thinking based on the context parameter theory accounts for only 3.2%. To a certain extent, it can be seen that people’s thinking about business English translation will be affected by different amounts of thinking. By mapping context parameters to corresponding factors, this paper analyzes the interpretation mechanism of translation semantics, to a certain extent, more intuitively expounds the semantic generation of business English translation, puts forward higher requirements for people’s translation ability, and further obtains new knowledge, so as to provide practical guidance for English translation.

“…For simplicity, we do not indicate here the indices in the notation of the retarded (advanced) Green functions. Just as in [18], we restrict ourselves to an approximation quadratic in fluctuating potential for the self-energy part. The components of the self-energy part have poles at the boundaries of the energy gap.…”

“…In Ref. [18] it was shown that, as a result of resonant scattering of charge carriers on thermal fluctuations of electron-hole pairs, in the normal and pairing components of the self-energy part there arise singularities (poles) at energy values corresponding to the boundaries of the energy gap E ≃ ±E k .…”

“…According to Ref. [18], singularities in the energy dependence of the self-energy part, can also arise as a result of resonant scattering of charge carriers by thermal fluctuations of electron-hole pairs, which significantly renormalizes the energy dependence of the self-energy. In this paper, to calculate TI, taking into account thermal fluctuations in superconducting phases, the functional-integral method is used in the general calculation scheme, which is similar to the calculation of TI in the quantum Hall effect based on the Kubo formula [19].…”

The behavior of thermal fluctuations of a superconducting order parameter with extended s and chiral d + id symmetry is investigated. The study is carried out on a triangular lattice within the framework of the quasi-two-dimensional single-band model with attraction between electrons at neighboring sites. The method of consistent consideration of the order parameter fluctuations and the charge carrier scattering by fluctuations of coupled electron pairs, based on the theory of functional integration is used. The distribution functions of the phase fluctuation probabilities depending on temperature and charge carrier concentration are obtained. The temperature dependences of the amplitudes of the averaged superconducting order parameter are calculated. A phase diagram of superconducting states is constructed for the entire range of variation in the charge carrier concentration 0 < n < 2. Near the boundaries of this range, topologically trivial superconducting states with extended s symmetry are realized, while a superconducting state with topologically nontrivial chiral d + id symmetry is realized between them. The calculated anomalous self-energies are compared with the experimental ones obtained using machine learning techniques

The behavior of the topological index (TI), characterizing the properties of superconducting phases of quasi-two-dimensional systems with nontrivial topology, is investigated depending on the temperature and system parameters. For this purpose, a method of calculating the TI, based on a self-consistent functional-integral theory, is proposed. The chiral d + id superconducting phase of a quasi-two-dimensional model with effective attraction between the electrons located at the nearest sites of a triangular lattice is considered. It is shown that the structure of the energy dependence of the self-energy function, which occurs when taking into account thermal fluctuations, does not lead to a change in the topological properties of the system. It is found that taking into account thermal fluctuations with an increase in the effective attraction between electrons expands the temperature range in which the value of the TI is close to the integer C 1 ≃ − 2 .
