По сравнению с - in comparison to, in comparison with, compared to, as compared to, when compared to; in relation to, relative to; over; from; versus; vis-a-vis; asHot water as a heating medium offers a number of advantages in comparison to steam, which are discussed in detail in [...].The average of the peak pressures under the babbitted shoes operating at 0.91 m/s is 1.95 MPa vis-a-vis the 1.66 MPa shown.The compressor disks have been designed to achieve twice the fatigue life in the C24 compressor as currently experienced in the C20.This influence is insignificant in comparison with the pressure waves.Compared to No. 5 fuel oil, SRC fuel oil would be substantially easier to burn.In addition, the throat aspect ratio of the air diffuser data was b/w = 4 as compared to b/w = 10 for the water diffuser data.This is insignificant when compared to the maximum capability of the system, which is about 3.3 radian.In addition, oil fuel combustion is slower in relation to the intense burning of natural gas from a highly mixed ring-type burner.However, the vacuum-exposed bars do show some loss of fatigue life relative to unexposed bars.In summary, the author's technical contribution does not appear to offer any obvious advantage over other published equilibrium programs.Turbines have different performance characteristics from piston engines because they utilize different approaches to thermal-mechanical energy conversion.The plating thickness in these regions was approximately 2.54 mm versus 25.4 mm over the rest of the cladding.Русско-английский научно-технический словарь переводчика > по сравнению с
