|---|---|---|---|
| 설명 | 인간이나 동식물의 건강-생활에 피해를 주는 인위적 발생원으로 인해 대기가 오염된 상태. 인간사회의 생산-유통-소비의 각 과정에서 배출되는 대기오염물질에 의해 사람의 건강은 물론 동식물-토양-지형-기후-수리 등으로 얽힌 생태계의 안정성이 방해될 때를 대기가 오염되었다고 한다. 여기에서 대기오염물질이란 대기의 조성을 변화시켜 인간사회나 생태계에 영향을 미칠 정도로 존재하는 천연 또는 인공물질을 말하며, 고체-액체-기체 또는 이들의 혼합물이 포함된다. 단일한 물질만으로 된 대기 오염물질은 드물며, 일반적으로는 많은 종류와 크기로 된 복합물질이다. 크게 나누면, 특정한 발생원에서 직접 방출되는 일차 오염물질과, 두 종류 이상의 일차 오염물질에 의한 상호작용이나 광화학반응 등에 의해 생긴 이차 오염물질이다. 매연, 먼지, 일산화탄소 따위와 같은 물질이 공기와 섞이는 일이 대기오염의 예이며, 그뿐 아니라 이산화탄소의 증가로 인하여 지구의 온난화, 그리고 프레온 가스로 인한 오존층의 파괴 따위가 문제시되고 있다. |

| spectrometry, mass, matrix-assisted laser desorption-ionization | A mass spectrometric technique that is used for the analysis of large biomolecules. Analyte molecules are embedded in an excess matrix of small organic molecules that show a high resonant absorption at the laser wavelength used. The matrix absorbs the laser energy, thus inducing a soft disintegration of the sample-matrix mixture into free (gas phase) matrix and analyte molecules and molecular ions. In general, only molecular ions of the analyte molecules are produced, and almost no fragmentation occurs. This makes the method well suited for molecular weight determinations and mixture analysis.

| ionization | <chemistry, radiobiology> Any process by which a neutral atom gains or loses electrons, thus acquiring a net charge, as the dissociation of a substance in solution into ions or ion production by the passage of radioactive particles. High temperatures, electrical discharges or nuclear radiations can cause ionisation. (16 Dec 1997) |
| ionization chamber | A chamber for detecting ionization of the enclosed gas; used for determining intensity of ionizing radiation. (05 Mar 2000) |
| flame ionization | Pyrolysis of organic compounds at the temperature of a hydrogen-air flame to produce ionic intermediates which can be collected and the resulting ion current measured by gas chromatography. (12 Dec 1998) |
| air | 1. The fluid which we breathe, and which surrounds the earth; the atmosphere. It is invisible, inodourous, insipid, transparent, compressible, elastic, and ponderable. By the ancient philosophers, air was regarded as an element; but modern science has shown that it is essentially a mixture of oxygen and nitrogen, with a small amount of carbon dioxide, the average proportions being, by volume: oxygen.96 per cent.; nitrogen.00 per cent.; carbon dioxide.04 per cent. These proportions are subject to a very slight variability. Air also always contains some vapor of water. 2. Symbolically: Something unsubstantial, light, or volatile. "Charm ache with air." "He was still all air and fire. (Macaulay). [Air and fire being the finer and quicker elements as opposed to earth and water]" 3. A particular state of the atmosphere, as respects heat, cold, moisture, etc, or as affecting the sensations; as, a smoky air, a damp air, the morning air, etc. 4. Any aeriform body; a gas; as, oxygen was formerly called vital air. 5. Air in motion; a light breeze; a gentle wind. "Let vernal airs through trembling osiers play." (Pope) 6. Odouriferous or contaminated air. 7. That which surrounds and influences. "The keen, the wholesome air of poverty." (Wordsworth) 8. Utterance abroad; publicity; vent. "You gave it air before me." (Dryden) 9. Intelligence; information. 10. A musical idea, or motive, rhythmically developed in consecutive single tones, so as to form a symmetrical and balanced whole, which may be sung by a single voice to the stanzas of a hymn or song, or even to plain prose, or played upon an instrument; a melody; a tune; an aria. In harmonised chorals, psalmody, part songs, etc, the part which bears the tune or melody in modern harmony usually the upper part is sometimes called the air. 11. The peculiar look, appearance, and bearing of a person; mien; demeanor; as, the air of a youth; a heavy air; a lofty air. "His very air." 12. Peculiar appearance; apparent character; semblance; manner; style. "It was communicated with the air of a secret." (Pope) 12. An artificial or affected manner; show of pride or vanity; haughtiness; as, it is said of a person, he puts on airs. 14. The representation or reproduction of the effect of the atmospheric medium through which every object in nature is viewed. Carriage; attitude; action; movement; as, the head of that portrait has a good air. 15. The artificial motion or carriage of a horse. 16. To expose to the air for the purpose of cooling, refreshing, or purifying; to ventilate; as, to air a room. "It were good wisdom . . . That the jail were aired." (Bacon) "Were you but riding forth to air yourself." (Shak) 17. To expose for the sake of public notice; to display ostentatiously; as, to air one's opinion. "Airing a snowy hand and signet gem." (Tennyson) 18. To expose to heat, for the purpose of expelling dampness, or of warming; as, to air linen; to air liquors. Air is much used adjectively or as the first part of a compound term. In most cases it might be written indifferently, as a separate limiting word, or as the first element of the compound term, with or without the hyphen; as, air bladder, air-bladder, or airbladder; air cell, air-cell, or aircell; air-pump, or airpump. Air balloon. See Balloon. Air bath. An apparatus for the application of air to the body. An arrangement for drying substances in air of any desired temperature. Air castle. See Castle in the air, under Castle. Air compressor, a machine for compressing air to be used as a motive power. Air crossing, a passage for air in a mine. Air cushion, an air-tight cushion which can be inflated; also, a device for arresting motion without shock by confined air. Air fountain, a contrivance for producing a jet of water by the force of compressed air. Air furnace, a furnace which depends on a natural draft and not on blast. Air line, a straight line; a bee line. Hence Air-line,; as, air-line road. <medicine> Air lock Unsupported and liable to be turned or taken in flank; as, the army had its wing in the air. To take air, to be divulged; to be made public. To take the air, to go abroad; to walk or ride out. Origin: OE. Air, eir, F. Air, L. Aer, fr. Gr, air, mist, for, fr. Root to blow, breathe, probably akin to E. Wind. In sense 10 the French has taking a meaning fr. It. Aria atmosphere, air, fr. The same Latin word; and in senses 11, 12, 13 the French meaning is either fr. L. Aria, or due to confusion with F. Aire, in an older sense of origin, descent. Cf. Ary, Debonair, Malaria, Wind.
