Sovet tuzumi kommunizm qurishning asoslaridan biri sifatida sovet xalqini moʻljal qildi. Sovet xalqi kommunizm davrida millatlar unifikatsiyasi natijasi boʻlishi lozim edi. Millatlar unifikatsiyasi tillar unifikatsiyasini taqozo etar edi. Tillar unifikatsiyasi esa SSSR xalqlari tillarining qurilishi jihatdan “bir xillashuvi”ni taqozo etar, barcha milliy tillarning qurilishi sunʼiy ravishda rus tili qurilishi qoliplariga solingan edi. Buning uchun milliy tilshunosliklar rus tilshunosligi metodologiyasi asos ish koʻrdi. Milliy tillarda rus tili xususiyatlari boʻrttirildi. Bu, ayniqsa, tillarning tipologik xususiyatlari namoyon boʻladigan fonetika va grammatikada yaqqol koʻzga tashlandi. Boshqa milliy respublikalar kabi Oʻzbekiston ham mustaqillikka erishgandan soʻng oʻzbek tilshunosligi ham milliylasha boshladi. Bu oʻzbek tili fonetik-grammatik qurilishning milliy talqin etilishida, sharq tasavvuf falsafasining lingvistik tadqiq metodologiyasi sifatida ilmiy muomalaga kirishida namoyon boʻldi. Tasavvuf falsafasidagi zot va tajalli kategoriyasi tilga sistema sifatida yondashuvda, oʻzbek tilida lison va nutqni farqlashda katta metodologik rol oʻynadi.

The article discusses the mathematical modeling of the movement of viscous incompressible fluids through a bundle of tubes
located inside the outer pipe. The laminar and turbulent modes of this movement are considered, and the physical meaning of their occurrence is also analyzed. The fluid flow through n tubes of length L and radius r located inside the outer tube is considered. Calculation formulas are derived for calculating the maximum velocity of this flow, the volume of fluid passing through the cross section of the tube, the coefficient of resistance to friction in the tube along the length of the flow, and also the maximum value of the tangential stress. The results of the study of the relationship of the coefficient of resistance to friction in the tube with the Reynolds number are presented. A description is given of a device created according to the results of a study that brings the disordered flow of liquids into a laminar state
The concept of a system of nonlinear equations, the stages of solving the problem, the geometric interpretation of the solution of the
equation and the concept of iterative processes are given and their application is shown in the examples. The problem of numerical solution of a number of practical problems consisting of a system of nonlinear equations is considered. There are a number of approximate computational methods for solving systems of nonlinear equations, including Newton's method. Using these methods, a number of specific practical problems were solved, a computational algorithm and a block diagram were developed. An approximate method of finding the true roots of a system of nonlinear equations is given, based on examples, graphs are used in the form of results,
and appropriate conclusions are drawn
