During the second half of the twentieth century, Soviet scientists were among the world leaders in the theory and geometry of gearing or the theoretical fundamentals of designing gears and gear-cutting tools. The authors of the current paper review works related to the development of the theory of gearing （TG） written in Russian from the mid-1930s to the present. Overall, the review covers more than 400 publications of nearly 200 authors （among more than 1000 studied works）. This review involves some works on gear strength and accuracy to attract more experts. This paper presents a short list of works from the seventeenth century to the nineteenth century and discusses the basic concepts of the TG. This paper also includes a review of more than 160 papers in Russian for the period of 1935-1975, which is the ＂golden age＂ of the TG. The main features and achievements during this period are also considered. The distinctive feature of this review is the use of diagrams that visually present TG experts and the dates and themes of their published works. The diagrams also show the following aspects： 1） The most popular and important themes in a specific period, 2） the most important publications on the themes of interest to readers, and 3） the direction of the works and scope of interests of every researcher.

Andreev Reflection of Pseudo-Correlated Pairs Electrons in the System ＂Superconductor-Fluctuation Superconductor-Superconductor＂

引用

Journal of Physical Science and Application 2014年第3期4卷 188-192页

作者： Daulet Sergeyev Kuanyshbek Shunkeyev Aleksandra barmina Lyudmila Myasnikova Military Institute of Air Defense Forces 39 Moldagulova Avenue Aktobe 030012 Kazakhstan Aktobe State Pedagogical Institute 34A Moldagulova Avenue Aktobe 030012 Kazakhstan

In the article, the Josephson system ＂Superconductor-Fluctuation Superconductor-Superconductor＂, consisting of a combination of superconductors with a fluctuation superconductor was considered. The possibility of transformation of the superconducting （Cooper） pairs in psevdocorrelated （fluctuation） of a pair of electrons is shown, and vice versa, the fluctuation pairs in the Cooper pairs in such a Josephson system. The characteristic features of the Andreev reflection of the weakly bound electron, which is part of the fluctuation pairs in the interface ＂fluctuation superconductor-superconductor＂ with a probability of forming a pair of ＂Electron-Hole＂ and the generation of psevdocorrelated pair discussed. The probability of formation of two correlated superconducting electron pairs, forming original cluster with a charge 4e, in the interface ＂Fluctuation Superconductor-Superconductor＂ as a result of transmutation of the reflected hole into an electron or subjection Andreev reflection of both electrons of fluctuation pairs is viewed. The above processes may be useful for better understanding the fluctuation effects in superconducting materials which appear at temperatures above the critical value.

关键词： Josephson system Josephson effect Andreev reflection Josephson tunneling fluctuation superconductor.
