* * *Зависимость -- relation, relationship (выражения); function (функциональная); history (обычно временная); law (общеизвестная); variation, trend, behavior, pattern, characteristic (закономерность, характеристика); sensitivity, dependence (обусловленность)This resulted in a time-temperature history of the combustion gases, vastly different from that of the original burner design.Any major systematic deviation from the standard load/life law should have manifested itself in observed misprediction of lives in service.Зависимость между... иThe behavior of the heat transfer coefficient versus flow rate is different here from the classical Nusselt condensation problem.In the simplest option in the program a straight line relationship is taken for temperature rise against mass blow.Зависимость... отStrouhal number dependence of phase angle (Зависимость фазового угла от числа Струхаля)It became evident that the schedule of casing width versus radius is an arbitrary constraint.The lack of response of performance to variations in viscosity can be traced to the fact mentioned in Section 1.Русско-английский научно-технический словарь переводчика > зависимость

Определённый - definite, distinct (явный); certain (некоторый); (as) defined, (as) determined (расчётом или измерением)The inhibition increases to a definite limit and can then increase no further.A certain increase in the heat transfer coefficient with tube spacing was observed at some film flow rates.In reducing the data, pressure recoveries were referenced to the mass averaged dynamic pressure at the diffuser inlet, as defined by 19 point radial traverses across this plane.
