| 설명 | 사람의 귀에 소리로 들리는 한계 주파수 이상이어서 들을 수 없는 음파. 파장이 작고 지향성이 강하기 때문에 그 펄스를 발전시켜 바다의 깊이를 재는 음파 탐지기나 어군 탐자기에 이용한다. 같은 원리로 고체 재료의 내부 결함을 검사하거나, 보석-유리 따위의 절단이나 가공, 유탁액의 생성-세척-살균 따위에도 이용한다. |

| vibration | 1. The act of vibrating, or the state of being vibrated, or in vibratory motion; quick motion to and fro; oscillation, as of a pendulum or musical string. "As a harper lays his open palm Upon his harp, to deaden its vibrations." (Longfellow) 2. <physics> A limited reciprocating motion of a particle of an elastic body or medium in alternately opposite directions from its position of equilibrium, when that equilibrium has been disturbed, as when a stretched cord or other body produces musical notes, or particles of air transmit sounds to the ear. The path of the particle may be in a straight line, in a circular arc, or in any curve whatever. Vibration and oscillation are both used, in mechanics, of the swinging, or rising and falling, motion of a suspended or balanced body; the latter term more appropriately, as signifying such motion produced by gravity, and of any degree of slowness, while the former applies especially to the quick, short motion to and fro which results from elasticity, or the action of molecular forces among the particles of a body when disturbed from their position of rest, as in a spring. Amplitude of vibration, the maximum displacement of a vibrating particle or body from its position of rest. Phase of vibration, any part of the path described by a particle or body in making a complete vibration, in distinction from other parts, as while moving from one extreme to the other, or on one side of the line of rest, in distinction from the opposite. Two particles are said to be in the same phase when they are moving in the same direction and with the same velocity, or in corresponding parts of their paths. Origin: L. Vibratio: cf. F. Vibration.

| vibration syndrome | <syndrome> Tingling, numbness, and blanching of the fingers resulting from use of hand-held vibration tools; may persist without further exposure to vibration. (05 Mar 2000) |
| vibration tolerance | The maximum vibratory or oscillatory movements that an individual can experience and bear without pain; the limit of tolerance is a function of amplitude and frequency of the vibration and varies with the direction of application. (05 Mar 2000) |
| ultrasonic | Relating to energy waves similar to those of sound but of higher frequencies (above 30,000 Hz). Origin: ultra-+ L. Sonus, sound (05 Mar 2000) |
| ultrasonic cardiography | Echocardiography is a diagnostic test which uses ultrasound waves to make images of the heart chambers, valves and surrounding structures. It can measure cardiac output and is a sensitive test for inflammation around the heart (pericarditis). It can also be used to detect abnormal anatomy or infections of the heart valves. (12 Dec 1998) |
| ultrasonic cephalometry | Measurement of the foetal head by ultrasound. (05 Mar 2000) |
| ultrasonic egg recovery | Obtaining an egg for in vitro fertilization by means of an ultrasonically guided needle aspiration of ovarian follicles; may be performed transvesically or via the cul-de-sac. (05 Mar 2000) |
| ultrasonic lithotresis | The demolition of calculi by high frequency sound waves. (05 Mar 2000) |
| ultrasonic microscope | <instrument> A microscope that has lenses designed to use acoustic energy so that the ultrasonic wavelengths may be utilised; by means of transducers, the information is translated to a form that may be visualised or recorded. (05 Mar 2000) |
| ultrasonic nebuliser | A humidifier using high-frequency electricity to power a transducer that vibrates 1,350,000 times per second and changes water up into particles 0.5 to 3 um in size in its nebulizing chamber; used in inhalation therapy. (05 Mar 2000) |
