|---|---|---|---|
| 설명 | 눈을 한곳에 고정시킨 채, 관찰할 수 있는 주변공간을 시야라 한다. 시야를 검사하는 가장 간단한 방법은 대면검사(confronting test)이다. 이것은 피검사자의 눈을 검사자의 눈에 맞추어 보도록 하여 눈을 고정시킨채, 검사자가 손가락끝을 위쪽, 아래쪽, 왼쪽, 오른쪽, 그리고 비스듬히 경사진 곳 등으로 옮겨보아 피검사자가 관찰할 수 있는지 여부를 정하는 검사법이다. 이보다 정확한 검사법은 자동식 컴퓨터시야검사법이 있다. 대개, 눈자체의 이상이 있어도 시야검사에서 이상이 나오지만, 이외 뇌의 이상으로 시각의 형성경로에 이상이 있어도 역시 이상소견을 보인다. |

| electrostatic field | <radiobiology> The region surrounding an electric charge in which another charge experiences a force. (16 Dec 1997) |

| electrostatic | Pertaining to electrostatics. Source: Websters Dictionary (01 Mar 1998) |
|---|---|
| electrostatic analyser | <radiobiology> A device which filters an electron beam (band-pass), permitting only electrons within a narrow energy (velocity) range to pass. (09 Oct 1997) |
| electrostatic bond | Bond between atoms or groups carrying opposite charges (or, in some cases, partial charges). Synonym: heteropolar bond, salt bridge. (05 Mar 2000) |
| electrostatic confinement | <radiobiology> An approach to fusion based on confining charged particles by means of electric fields, rather than the magnetic fields used in magnetic confinement. (09 Oct 1997) |
| electrostatic force | <radiobiology> Like charges in close proximity produce forces of repulsion between them. Consequently if two surfaces bear appreciable and approximately equal densities of charged groups on their surfaces appreciable forces of repulsion may occur between them. The range of these forces is determined in the main by the ionic strength of the intervening medium, forces being of minimal range at high ionic strength. The forces are effective over approximately twice the double layer thickness. See: DLVO theory. (18 Nov 1997) |
| electrostatic lens | <physics> A lens employing a permanent magnet to produce a potential field capable of deflecting electron rays to form an image of an object. (cf. Electromagnetic lens). (05 Aug 1998) |
| electrostatic unit | The unit in an absolute system (CGS) of unit's utilizing static electricity; e.g., statampere, statcoulomb, statfarad, stathenry, statvolt. (05 Mar 2000) |
| electrostatic wave | <radiobiology> Longitudinal oscillations appearing in a plasma due to a perturbation of electric neutrality. For a cold unmagnetised plasma, or at large wavelengths, the frequency of these waves is by definition the plasma frequency. (09 Oct 1997) |
| auditory field | The space included within the limits of hearing of a definite sound, as of a tuning fork. (05 Mar 2000) |
| bright field illumination | <microscopy> The method of lighting the specimen with a solid cone of rays. Transmitted bright field illumination is performed by a substage condenser. Reflected bright field illumination is performed by a vertical illuminator. Compare: dark field illumination (05 Aug 1998) |
| bright field imaging | <microscopy> An imaging mode in a transmission electron microscopy that uses only unscattered Electrons to form the image. Contrast in such an image is due entirely to mass-thickness variations in amorphous samples, and may include diffraction contrast in crystalline samples. (05 Aug 1998) |
| bright field microscopy | <technique> Optical microscopy, in which absorption to a great extent and diffraction to a minor extent give rise to the image, as opposed to phase contrast or interference methods of microscopy. (18 Nov 1997) |
| Broca's field | The posterior part of the inferior frontal gyrus of the left or dominant hemisphere, corresponding approximately to Brodmann's area 44; Broca identified this region as an essential component of the motor mechanisms governing articulated speech. Synonym: Broca's area, Broca's field, motor speech centre. (05 Mar 2000) |
| cardioid dark field condenser | <microscopy> A condenser designed with two reflecting surfaces, the first, a spherical surface which reflects the rays to a second, cardioid (heart-shaped) surface. The virtue in such an arrangement is that, if the cardioid surface is of true figure, the lens is both achromatic and aplanatic. It has a limiting numerical aperture of about 1.0. Thus objectives of a greater numerical aperture cannot be used successfully with it. A true cardioid figure is the trace of a point on the circumference of a circle rolling around an equal, fixed circle. (05 Aug 1998) |
| magnetic field | The sphere of influence of a magnet. (05 Mar 2000) |
| electrostatic field | electric field associated with static electric charges |
