| 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. |

| cleaning | In dentistry, a procedure whereby accretions are removed from the teeth or from a dental prosthesis. See: dental prophylaxis. Ultrasonic cleaning, in dentistry, the use of a high-frequency vibrating point to remove deposits from tooth structure; also the process of cleaning dentures by placing them in a special liquid in a container that generates high-frequency vibrations.

| cleaning-in-place | <procedure> Cleaning and sterilising a bioreactor system without dismantling it. (14 Nov 1997) |
| ear canal, self-cleaning | most of the time the ear canals are self-cleaning, that is, there is a slow and orderly migration of ear canal skin from the eardrum to the outer opening. Old earwax is constantly being transported from the deeper areas of the ear canal to the opening where it usually dries, flakes, and falls out. (12 Dec 1998) |
| ear cleaning | When so much wax accumulates that it blocks the ear canal (and hearing), your physician may have to wash it out, vacuum it, or remove it with special instruments. Alternatively, your physician may prescribe ear drops what are designed to soften the wax (such as Cerumenex). Never put anything smaller than your elbow in your ear! Wax is not formed in the deep part of the ear canal near the eardrum, but only in the outer part of the canal. So when a patient has wax pushed up against the eardrum, it is often because he has been probing his ear with such things as cotton-tipped swabs (such as Q-Tips), bobby pins, or twisted napkin corners. Such objects only serve as ramrods to push the wax in deeper. Also, the skin of the ear canal and the eardrum is very thin, fragile and easily injured. The ear canal is more prone to infection after it has been whipped clean of the good coating type wax. In addition, we have seen many perforated eardrums as a result of these efforts. (12 Dec 1998) |
| electron cyclotron discharge cleaning | Using relatively low power microwaves (at the electron cyclotron frequency) to create a weakly ionised, essentially unconfined hydrogen plasma in the vacuum chamber. The ions react with impurities on the walls of the tokamak and help remove them from the chamber. For instance, Alcator C-mod typically applies electron cyclotron discharge cleaning for a few days prior to beginning a campaign, and a few hours before each day's run. (09 Oct 1997) |
| 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) |
| ultrasonic rays | See: ultrasonic. (05 Mar 2000) |
| ultrasonic scaler | An ultrasonic instrument that uses high frequency vibration to remove adherent deposits from the teeth. (05 Mar 2000) |
| ultrasonic therapy | The use of focused, high-frequency sound waves to produce local hyperthermia in certain diseased or injured parts of the body or to destroy the diseased tissue. (12 Dec 1998) |
