| 설명 | 점이나 또는 평면에서 양쪽에 있는 부분이 똑같은 형으로 배치되어 있는 것. 점인 경우는 점대칭, 평면인 경우는 평면대칭이라 한다. 평면상에 두 개의 도형 F와 F-가 있을 때 F상의 점 P와 F-상의 점 P-를 대응시켜 대응하는 점 P와 P-를 연결하는 항상 하나의 정점 O로써 이등분된다면 도형 F와 F-는 점 O에 대하여 점대칭이다. 또한 평면상의 두 도형 F와 F-가 있을 때 F상의 점 P와 F-상의 점 P-를 대응시켜 대응하는 점 P와 P-를 연결한 선이 항상 일정한 직선1에 의해 수직 이등분되면 도형 F와 F-는 직선에 대해 선대칭이다. 같은 방법으로 공간에서의 면대칭을 정의할 수 있다. |

| bilateral symmetry | <biology> Describes an organism which is divisible into equal mirror halves in one plane only. (09 Oct 1997) |
| pseudo-symmetry | <chemistry> A kind of symmetry characteristic of certain crystals which from twinning, or other causes, come to resemble forms of a system other than that to which they belong, as the apparently hexagonal prisms of aragonite. Origin: Pseudo- + symmetry. Source: Websters Dictionary (01 Mar 1998) |
| symmetry | 1. A due proportion of the several parts of a body to each other; adaptation of the form or dimensions of the several parts of a thing to each other; the union and conformity of the members of a work to the whole. 2. <biology> The law of likeness; similarity of structure; regularity in form and arrangement; orderly and similar distribution of parts, such that an animal may be divided into parts which are structurally symmetrical. Bilateral symmetry, or two-sidedness, in vertebrates, etc, is that in which the body can be divided into symmetrical halves by a vertical plane passing through the middle; radial symmetry, as in echinoderms, is that in which the individual parts are arranged symmetrically around a central axis; serial symmetry, or zonal symmetry, as in earthworms, is that in which the segments or metameres of the body are disposed in a zonal manner one after the other in a longitudinal axis. This last is sometimes called metamerism. 3. <botany> Equality in the number of parts of the successive circles in a flower. Likeness in the form and size of floral organs of the same kind; regularity. Axis of symmetry. <geometry> See Axis. Respective symmetry, that disposition of parts in which only the opposite sides are equal to each other. Origin: L. Symmetria, Gr.; with, together + a measure: cf. F. Symetrie. See Syn-, and Meter rhythm. Source: Websters Dictionary (01 Mar 1998) |
| symmetry axis | <radiobiology> The straight line (usually vertical) through the centre of a configuration, when the configuration is symmetric to all (axisymmetric, like the tokamak) or some (periodic, like the stellarator) rotations about this line. Usually the z-axis. (09 Oct 1997) |
| dyad symmetry element | Dyad symmetry element bound by serum response factor to control the expression of c fos. (18 Nov 1997) |
| dyad symmetry of DNA | <molecular biology> Two areas of a DNA molecule whose base pair sequences are repeats of each other, inverted relative to each other, or are palindromes. (09 Oct 1997) |
| inverse symmetry | Correspondence of the right or left side of an asymmetrical individual to the left or right side of another. (05 Mar 2000) |
| universal | 1. Of or pertaining to the universe; extending to, including, or affecting, the whole number, quantity, or space; unlimited; general; all-reaching; all-pervading; as, universal ruin; universal good; universal benevolence or benefice. "Anointed universal King." "The universal cause Acts not by partial, but by general laws." (Pope) "This universal frame began." (Dryden) Universal and its derivatives are used in common discourse for general and its derivatives. See General. 2. Constituting or considered as a whole; total; entire; whole; as, the universal world. "At which the universal host up dent A shout that tore Hell's concave." (Milton) 3. <mechanics> Adapted or adaptable to all or to various uses, shapes, sizes, etc.; as, a universal milling machine. 4. <logic> Forming the whole of a genus; relatively unlimited in extension; affirmed or denied of the whole of a subject; as, a universal proposition; opposed to particular; e. G. (universal affirmative) All men are animals; (universal negative) No men are omniscient. 5. Universal dial, a dial by which the hour may be found in any part of the world, or under any elevation of the pole. 6. <astronomy> Universal instrument, a contrivance used for joining two shafts or parts of a machine endwise, so that the one may give rotary motion to the other when forming an angle with it, or may move freely in all directions with respect to the other, as by means of a cross connecting the forked ends of the two shafts. Since this joint can not act when the angle of the shafts is less than 140 deg, a double joint of the same kind is sometimes used for giving rotary motion at angles less than 140 deg. 7. <botany> Universal umbel, a primary or general umbel; the first or largest set of rays in a compound umbel; opposed to partial umbel. A universal involucre is not unfrequently placed at the foot of a universal umbel. Synonym: General, all, whole, total. Origin: L. Universalis: cf. F. Universel, OF. Also universal. (10 Mar 1998) |
| universal antidote | <pharmacology> A preparation of activated charcoal that can adsorb and therefore neutralise many toxic chemicals. (09 Oct 1997) |
| universal appliance | A combination of the edgewise and ribbon arch appliance techniques, affording precise control of individual teeth in all planes of space. (05 Mar 2000) |
| universal coverage | Health insurance coverage for all persons in a state or country, rather than for some subset of the population. It may extend to the unemployed as well as to the employed; to aliens as well as to citisens; for pre-existing conditions as well as for current illnesses; for mental as well as for physical conditions. (12 Dec 1998) |
| universal donor | In blood grouping, a person belonging to group O; i.e., one whose erythrocytes do not contain either agglutinogen A or B and are, therefore, not agglutinated by plasma containing either of the ordinary isoagglutinins, alpha or beta. (05 Mar 2000) |
| universal gas constant | <radiobiology> R = 8.314 x 10^7 ergs per degree C per mole. (09 Oct 1997) |
| universal infantilism | Dwarfism generally associated with hypogonadism; may be caused by deficient secretion of anterior pituitary hormones. Synonym: Lorain's disease, proportionate infantilism, universal infantilism. (05 Mar 2000) |
