One-dimensional hemodynamic models have proven themselves well in the study of global blood flow in the human body in normal and pathological conditions. One of the key issues of successful modelling using one-dimensional models is taking into account the elastic properties of the walls of blood vessels. This work is devoted to the comparative analysis of various mathematical descriptions of the elastic properties of vascular walls in modern models of one-dimensional hemodynamics. Approaches to modelling blood flow using one-dimensional network models. They have developed successfully in recent decades. This class of models has proven itself well in the study of global blood flow in the human body, solving problems of the transport of substances by blood, features of hemodynamics in pathological changes in the body.

Ushbu maqolada ingliz va qoraqalpoq tillaridagi numerativ birliklarning grammatik tuzilishidagi xususiyatlari tahlil qilinadi. Numerativ birliklar son va miqdorni ifodalashda har ikki tilda muhim rol o'ynaydi, ammo ularning shakllanishi va ishlatilishi turlicha. Ingliz tilida numerativ birliklar sonli birliklarni ko'rsatish uchun oddiy sonlar bilan bog'lanib, ismlarning ko'plik shaklini talab qiladi. Qoraqalpoq tilida esa numerativ birliklar, ko'pincha maxsus so'zlar yordamida ifodalanib, ismlarga qo'shiladi va grammatik jihatdan o'zaro muvofiqlashtirilgan bo'ladi. Maqolada, har ikki tildagi numerativ birliklarning o'xshashliklari va farqlari misollar yordamida ko'rsatilgan.
