isobaric (adj)
|
/aɪsəˈbærɪk/
|
ia type of thermodynamic process in which the pressure of the system stays constant.
|
The relationship between the isobaric and adiabatic processes is quite obscure.
|
изобарический
|
adiabatic (adj)
|
/ædɪəˈbætɪk/
|
a type of thermodynamic process which occurs without transferring heat or mass between the system and its surroundings
|
The relationship between the isobaric and adiabatic processes is quite obscure.
|
адиабатический
|
isovolumetric (adj)
|
isovolumetric
|
A thermodynamic process that takes place at constant volume so that no work is done on or by the system.
|
A work equals zero in isovolumetric process.
|
изоволюметрический
|
isothermal (adj)
|
/aɪsəˈθɜːm(ə)/
|
a type of thermodynamic process in which the temperature of the system remains constant.
|
Only one point that often confuses people is the distinction between isothermal vs. Adiabatic.

|
/ˈenʤɪn/
|

|
longitudinal (adj)
|
/ˌlɒŋ.ɡɪˈtʃuː.dɪ.nəl/
|
running lengthwise rather than across
|
Longitudinal waves include sound waves (vibrations in pressure, a particle of displacement, and particle velocity propagated in an elastic medium) and seismic P-waves (created by earthquakes and explosions).
|
продольный
|
rarefaction (n, u)
|
/ˌreərɪˈfækʃən/ (ə)n
|
the reduction of an item's density, the opposite of compression
|
A common rarefaction wave is the area of low relative pressure following a shock wave (see picture)
|
разрежение
|
audible (adj)
|
/ ˈɔːdəbl/
|
Sounds that can be detected with a human ear
|
The human ear is sensitive to every minute pressure difference in the air if they are in the audible frequency range.
|
слышимый
|
ultrasonic (adj)
|
/ ˌʌltrəˈsɒnɪk/
|
frequencies higher than the upper audible limit of human hearing.
|
Ultrasonics, vibrations of frequencies greater than the upper limit of the audible range for humans—that is, greater than about 20 kilohertz
|
ультразвуковой
|
intensity (n, u)
|
/ ɪnˈtɛnsɪti/
|
the power transferred per unit area, where the area is measured on the plane perpendicular to the direction of propagation of the energy
|
The more intense the light reaching us is, the “brighter” the light appears to be
|
интенсивность
|
the Doppler effect
|
/ ðə Doppler ɪˈfɛkt/
|
he change in frequency of a wave in relation to an observer who is moving relative to the wave source
|
The total Doppler effect may therefore result from motion of the source, motion of the observer, or motion of the medium.
|
эффект Доплера
|
resonance (n, u)
|
/ ˈrɛznəns/
|
the phenomenon of increased amplitude that occurs when the frequency of a periodically applied force is equal or close to a natural frequency of the system on which it acts
|
Resonance manifests itself in many linear and nonlinear systems as oscillations around an equilibrium point.
