| 영문 | electro beam | 한글 | 전자선 |
|---|---|---|---|
| 설명 | 전자총에서 나오는 속도가 거의 균일한 전자의 연속적 흐름. X선과 마찬가지로 분자나 결정격자에 의해 전자빔의 간섭, 회절 효과를 관측할 수 있어서 분자의 구조를 알아내는 데 사용을 할 수가 있다. 그리고 물체에의 전자의 조사에 이용되기도 하는데, 악성종양에 대한 전자선 요법으로서는 라듐 B 또는 메소토륨같은 방사성 물질을 환부 가까이 위치시켜서 직접 전자선을 투여하여 악성 종양을 치료하는 방법이 있다. |

| beam-beam reaction | <radiobiology> Fusion reaction which occurs from the collision of two fast ions originating in injected neutral beams. (09 Oct 1997) |

| absolute configuration | <chemistry> The three-dimensional arrangement of the atoms around the chiral centre of a molecule. (09 Oct 1997) |
| cis configuration | <molecular biology> The configuration of an organic molecule containing a double bond between two carbon atoms, where the largest, most complex R groups are on the same side: H H \ / C=C / \ H3C CH3 -OR-The configuration of an organic molecule containing a ring, where the largest, most complex R groups are on the same side: H H | ___ \ / | // \\ [ring viewed edge-on] | \___/ / \ | /---\ H3C CH3 | H3C CH3. A genetics term meaning an event or a gene whose action occurs on the same chromosome. Two mutations in different genes coding for the same phenotype which are on the same chromosome (as opposed to the trans configuration where each homologue has one of the mutations). Compare: trans configuration. (11 Jan 1998) |
| configuration | <chemistry> The three-dimensional arrangement of an organic molecule that is caused by: double bonds that prevent free rotation, or chiral centres that haveside groups arranged around them in a particular order. A configurational isomer cannot be turned into another configuration without breaking covalent bonds. (09 Oct 1997) |
| stereochemical configuration | <chemistry> The arrangement of atoms in a molecule in three-dimensional space, especially with regard to the differences between enantiomers. The arrangements are specified in chemical formulas with the letters R, S, L, and/or D. In the R, S system, each asymmetric carbon atom is classified as R (for rectus, Latin for right) if the chemical groups attached to it have decreasing priorities in a clockwise direction, or S (for sinister, Latin for left) if the chemical groups attached to it have decreasing priorities in a counterclockwise direction, when the carbon atom in question is viewed along the bond of the chemical group with the lowest priority. Priorities are assigned to chemical groups according to the Cahn-Ingold Prelog priority rules (generally, the larger the group the higher the priority). L and D designations are given if the enantiomers have optical activity, that is, if they will rotate polarized light. The member of the pair which rotates polarized light clockwise is dextrorotatory, or D, and the member of the pair which rotates polarized light counterclockwise is levorotatory, or L (there is always one of each in every pair). This is also often referred to as handedness, where D is right-handed and L is lefthanded. (13 Nov 1997) |
| degenerate configuration | <radiobiology> Magnetic field configuration in which the magnetic lines of force close exactly on themselves after passing around the configuration a finite number of times. (09 Oct 1997) |
| trans configuration | 1. <chemistry> The configuration of an organic molecule containing a double bond between two carbon atoms, where the largest, most complex R groups attached to each carbon are on opposite sides. Alternatively: The configuration of an organic molecule containing a ring, where the largest, most complex R groups attached to each carbon are on opposite sides. These configurations are the opposite of cis configuration. 2. <genetics> A genetics term meaning that the changes in gene expression are due to something acting on the gene from a distance, or from an unrelated location, rather than on the same strand of DNA. Two mutations in different genes coding for the same phenotype which are on opposite homologous chromosomes (as opposed to the cis configuration where both of the mutations are on the same homologue). (17 Mar 1998) |
| field-reversed configuration | <radiobiology> A compact torus produced in a theta pinch and having (in principle) no toroidal field. The potential advantages for a fusion reactor include a simple (linear) machine geometry, an average plasma pressure close to the confining field pressure, and physical separation of formation and burn chambers. The are predicted to be violently unstable to tilting, but this is rarely observed. (09 Oct 1997) |
| advanced multiple-beam equalization radiography | A variant of scanning equalization radiography using several X-ray beams. (05 Mar 2000) |
| Balkan beam | An overhead frame, supported on uprights attached to the bedposts or to a separate stand, from which a splinted limb is slung in the treatment of fracture or joint disease. Synonym: Balkan beam, Balkan splint. (05 Mar 2000) |
| beam | <radiobiology> Stream of particles or electromagnetic radiation travelling in a single direction. (09 Oct 1997) |
| beam dump | <radiobiology> A mass of shielding material which absorbs the energy of a beam of particles or electromagnetic radiation. (09 Oct 1997) |
| beam-plasma reaction | <radiobiology> Fusion reaction which occurs from the collision of a fast beam ion with a thermal plasma ion. (09 Oct 1997) |
| beam splitter | <radiobiology> Optical device for dividing a beam of electromagnetic radiation into two or more separate beams. (09 Oct 1997) |
| beam tree | <botany> A tree (Pyrus aria) related to the apple. Origin: AS. Beam a tree. See: Beam. Source: Websters Dictionary (01 Mar 1998) |
