Figure4shows the contours of theQcriterion of the REST inlet symmetry surface, allowing to more clearly observe the turbulence and vortex structure. It is defined as:
包装专业英语 Lesson 12 Shock, Vibration, and Compression
The term shock wave is defined as a type of propagating disturbance, and it occurs when a wave moves faster than the local speed of sound in a fluid. Like an ordinary wave, a shock wave carries energy and propagates through a medium, however, it is characterized by an abrupt, nearly ...
Total harmonic distortion (THD) is the summation of the amplitudes of various harmonics when a pure sine tone is entered into a system. It measures how accurately a vibration system reproduces the output signal from a controller and is expressed as a ratio of the harmonic components to the fu...
the shock wave source used in this case consists of a cylindrical coil combined with a reflector in the form of a rotation paraboloid to focus the shock waves. This provides an accurately defined focal zone, which can be reproduced with maximum precision both axially (in depth) and laterally....
This phenomenon is defined as “local unstart” and has discussed by Jiao [18]. Unlike the generic inlet unstart, a local unstart has a subsonic region at the cowl side and a bow shock before the cowl lip. The figure of this local unstart condition is shown in Fig. 10. Sign in ...
RSS defined by a bedside score equal to or higher than 2 and a computed score equal to or higher than 3.5 was associated with a significant increase in mortality. This ESPNIC definition of RSS accurately identifies children with the most severe form of septic shock. The online version of ...
Total pressure is defined as that obtained by bringing gas to rest isentropically. Now the model flow of a uniform stream of gas of unit area flowing through a shock is extended upstream by assuming the gas to now have the conditions of suffix 1 by expansion from a reservoir of pressure ...
that are the result of deformation along crystal planes during impact. The result is absolutely parallel planes that cut across the crystal and occur in characteristic crystallographic directions. The two most common directions areω{1013} andπ{1012} (Bohor et al., 1987). To qualify as shocked...
As such, reliable stratification of outcome risk is fundamental to effective clinical practice and clinical research (Marshall J. Leukoc. Biol. 83:471-82 (2008)), as is the ability to differentiate between subclasses of septic shock that have different biology. Endotypes are biologically defined ...
