|---|---|---|---|
| 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. |

| toroidal field coils | <radiobiology> Coils in a toroidal system, typically wound around the torus in a solenoid-like arrangement, used to generate the toroidal magnetic field. Each turn completely surrounds the plasma. (09 Oct 1997) |
|---|
| field shaping coils | <radiobiology> Type of poloidal field coils (in a tokamak) which create magnetic fields which shape and control the plasma. Used to constrain horizontal and vertical displacements of the plasma, as well as (in some configurations) produce non-circular plasma cross-sections (poloidal cross-section) and/or create one or more divertor separatrices. (09 Oct 1997) |
|---|---|
| deflection coils | <microscopy> The electromagnetic coils that steer the electron beam in a cathode-ray tube or image pickup tube, for example, in a raster scan (05 Aug 1998) |
| advanced toroidal facility | <physics> A large stellarator device developed at Oak Ridge National Lab (ORNL), but now retired. Acronym: ATF (09 Oct 1997) |
| toroidal | <radiobiology> In the shape of a torus, or doughnut. Or: Coordinate indicating which part of the torus a particle is in. (Azimuthal coordinate, toroidal angle, etc.) Or: General term referring to toruses as opposed to other geometries. (for example, tokamaks and stellarators are examples of toroidal devices.) (09 Oct 1997) |
| toroidal beta | <radiobiology> Plasma beta using the toroidal magnetic field, i.e. Plasma pressure divided by toroidal field pressure. See: beta. (09 Oct 1997) |
| toroidal current | <radiobiology> Current flowing in the toroidal direction (the long way) around a torus. (As distinct from poloidal currents flowing through the centre of the torus and around to the outside, the short way.) (09 Oct 1997) |
| toroidal divertor | <radiobiology> Divertor created by extracting toroidal field field lines at some point, forming an external loop outside the torus. Has the disadvantages that it breaks the axial symmetry of the torus, which converts a relatively simple, mostly 2-dimensional geometry to a comples 3-dimensional geometry. For an illustration refer to page 135 of Gross (reference 4). (09 Oct 1997) |
| toroidal flux | <radiobiology> Magnetic field flux in the toroidal direction. See: magnetic fields. (09 Oct 1997) |
| toroidal magnetic cusps | A hybrid confinement scheme operating at high beta. A region of closed toroidal magnetic flux with high-beta plasma is separated by a narrow sheath from the surrounding field, which contains externally produced poloidal components arranged in a toroidal line-cusp configuration. Plasma migrating to the outer sheath is temporarily mirror-confined before being removed in a divertor system. (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) |
