Resonance
(gcide) | Resonance \Res"o*nance\ (r?z"?-nans), n. [Cf. F. r['e]sonance,
L. resonantia an echo.]
1. The act of resounding; the quality or state of being
resonant.
[1913 Webster]
2. (Acoustics) A prolongation or increase of any sound,
either by reflection, as in a cavern or apartment the
walls of which are not distant enough to return a distinct
echo, or by the production of vibrations in other bodies,
as a sounding-board, or the bodies of musical instruments.
[1913 Webster]
3. (Physics) A phenomenon in which a vibration or other
cyclic process (such as tide cycles) of large amplitude is
produced by smaller impulses, when the frequency of the
external impulses is close to that of the natural cycling
frequency of the process in that system.
Note: The shattering of a glass object when impinged upon by
sound of a certain frequency is one example of this
phenomenon; another is the very large tides in certain
basins such as that of the Bay of Fundy, which has a
natural cycling frequency close to that of the tidal
cycle.
[PJC]
4. (Electronics) An electric phenomenon corresponding to that
of acoustic resonance, due to the existance of certain
relations of the capacity, inductance, resistance, and
frequency of an alternating circuit; the tuning of a radio
transmitter or receiver to send or detect waves of
specific frequencies depends on this phenomenon.
[Webster 1913 Suppl. +PJC]
Pulmonary resonance (Med.), the sound heard on percussing
over the lungs.
Vocal resonance (Med.), the sound transmitted to the ear
when auscultation is made while the patient is speaking.

(wn) | resonance
n 1: an excited state of a stable particle causing a sharp
maximum in the probability of absorption of electromagnetic
radiation
2: a vibration of large amplitude produced by a relatively small
vibration near the same frequency of vibration as the natural
frequency of the resonating system
3: having the character of a loud deep sound; the quality of
being resonant [syn: plangency, resonance,
reverberance, ringing, sonorousness, sonority,
vibrancy]
4: a relationship of mutual understanding or trust and agreement
between people [syn: rapport, resonance]
5: the quality imparted to voiced speech sounds by the action of
the resonating chambers of the throat and mouth and nasal
cavities |

nukleární magnetická resonance
(czen) | nukleární magnetická resonance,NMR[zkr.] [chem.] -pv- |
magnetic resonance
(gcide) | magnetic resonance \magnetic resonance\ n. (Physics)
A phenomenon resulting from quantization in the magnetic
field of electrons or atoms or molecules or nuclei exposed to
an external magnetic field, by which a narrow frequency band
of radio waves may be absorbed and re-emitted by the object.
[WordNet 1.5 +PJC] |
magnetic resonance imaging
(gcide) | magnetic resonance imaging \mag*net"ic res"on*ance im"ag*ing\ n.
(Medicine)
a medical diagnostic procedure utilizing the phenomenon of
nuclear magnetic resonance to generate images of internal
parts of the body. It depends on the differential absorption
of electromagnetic radiation by different types of living
tissue in a magnetic field. It is complementary to X-ray
imaging in that the softer tissue show more prominently in
magnetic resonance images, rather than bone, as with X-rays.
It is a non-invasive procedure, allowing such images to be
obtained without penetration of the tissue by objects. It is
abbreviated MRI. As with computerized tomography, the
results are usually presented as images of sequential planar
sections of that part of the body of concern to the
physician.
[PJC] |
nuclear magnetic resonance
(gcide) | nuclear magnetic resonance \nu"cle*ar mag*net"ic res"on*ance\ n.
(Physics)
The specific absorption and re-emission of electromagnetic
radiation at characteristic wavelengths by atomic nuclei in a
magnetic field. It is abbreviated NMR. The wavelength of
the radiation absorbed depends on the type of nucleus, the
intensity of the magnetic field, and the local chemical
environment in which the nucleus resides. It is the latter
effect (called the chemical shift), by which atoms of
specific elements in different chemical compounds show a
different resonance frequency, which gives rise to the
greatest utility of this phenomenon in analyzing the chemical
structure of substances. Similar effects of the chemical
environment permit the discrimination of different types of
living tissue by virtue of their different chemical
composition, thus permitting utilization of the phenomenon in
medical diagnostic instruments, especially for {magnetic
resonance imaging}.
