71Thermodynamics — Annotated color version of the original 1824 Carnot heat engine showing the hot body (boiler), working body (system, steam), and cold body (water), the letters labeled according to the stopping points in Carnot cycle …
72Thermodynamic system — A thermodynamic system is a precisely defined macroscopic region of the universe, often called a physical system, that is studied using the principles of thermodynamics. All space in the universe outside the thermodynamic system is known as the… …
73уравнение баланса — кинетическое уравнение скоростное уравнение Уравнение, устанавливающее зависимость между изменением во времени населенности энергетических уровней и вероятностями переходов с учетом действия электромагнитных полей. [Сборник рекомендуемых терминов …
74AC power — This article deals with power in AC systems. See Mains electricity for information on utility supplied AC power. Usually hidden from the unaided eye, the blinking of (non incandescent) lighting powered by AC mains is revealed in this motion… …
75Cant deficiency — The term cant deficiency is defined in the context of travel of a rail vehicle at constant speed on a constant radius curve. Cant itself is a British synonym for the superelevation of the curve, that is, the elevation of the outside rail minus… …
76Runoff model (reservoir) — A runoff model is a mathematical model describing the rainfall runoff relations of a rainfall catchment area or watershed. More precisely, it produces the surface runoff hydrograph as a response to a rainfall hydrograph as input. In other words,… …
77Mathematical exposure modeling — is an indirect method of determining exposure, particularly for human exposure to environmental contaminants. It is useful when direct measurement of pollutant concentration is not feasible because direct measurement sometimes requires skilled… …
78Nuclear reactor physics — See also: Critical mass Nuclear reactor physics is the branch of science that deals with the study and application of chain reaction to induce controlled rate of fission for energy in reactors. Most nuclear reactors use a chain reaction to induce …
79Constant flux calorimetry — A key part of Reaction Calorimetry is the ability to control temperature in the face of extreme thermal events. Once the temperature is able to be controlled measurement of a variety of parameters can allow an understanding of how much heat is… …
80Entropy (classical thermodynamics) — In thermodynamics, entropy is a measure of how close a thermodynamic system is to equilibrium. A thermodynamic system is any physical object or region of space that can be described by its thermodynamic quantities such as temperature, pressure,… …
