| 설명 | 혈압, pH 등과 같이 생체의 기능 및 상태를 안정시키고자 하는 작용 : pH 7인 순수한 물에서 소량의 산 또는 알칼리를 가하면 그 양에 따라 물의 pH가 뚜렷하게 변한다. 그러나 약한 산과 그 염의 혼합용액, 또는 약한 산기와 그 염의 혼합용액으로 이루어지는 계에서는 약간의 산 또는 알칼리를 가해도 완충작용 때문에 pH는 거의 변하지 않는다. 예를 들어, 약한 산과 그 염의 혼합용액으로 이루어지는 계系에 산을 가했을 때를 생각하면, 산에 의해서 가해진 수소이온 H+은 약한 산이온과 결합하여 비해리인 산이 되어 pH가 변하지 않는다. 또 알칼리를 가했을 때는 가해진 수산이온 OH－이 H+과 결합하여 물을 만들고, 부족한 H+은 비해리 약한 산의 해리에 의해서 보충되므로써 역시 pH는 변하지 않는다. |

| 설명 | 폐활량(가능한 한 깊게 들여 마신 시점부터 천천히 한껏 내쉰 용량)에 잔기량(최대 날숨위치에서 폐내에 남은 용량. 약 1,200mL)을 합한 것이다. 건강한 성인은 6,000~7,000mL. 폐기종, 만성 기관지염 등의 폐색성 장애로 증가하게 되는 한편 허파섬유증, 무기폐, 흉수, 흉곽변형 등의 구속성 장애로 감소한다. |

buffer
| buffer capacity | <chemistry> The ability of a buffer solution to absorb added alkali or acid while maintaining the solution's pH. (09 Oct 1997) |
|---|
| buffer | <biochemistry, chemistry> A system that acts to minimise the change in concentration of a specific chemical species in solution against addition or depletion of this species. PH buffers: weak acids or weak bases in aqueous solution. The working range is given by pKa +/ 1. Metal ion buffers: a metal ion chelator for example EDTA, partially saturated by the metal ion acts, as a buffer for the metal ion. (18 Nov 1997) |
|---|---|
| buffer index | The power of a substance in solution to absorb acid or alkali without change in pH; this is highest at a pH value equal to the pKa value of the acid of the buffer pair. See: buffer capacity. Synonym: buffer index. (05 Mar 2000) |
| buffer pair | An acid and its conjugate base (anion). (05 Mar 2000) |
| buffer value | The power of a substance in solution to absorb acid or alkali without change in pH; this is highest at a pH value equal to the pKa value of the acid of the buffer pair. See: buffer capacity. Synonym: buffer index. (05 Mar 2000) |
| buffer value of the blood | The ability of the blood to compensate for additions of acid or alkali without disturbance of the pH. (05 Mar 2000) |
| buffer zone | <ecology> An area of land separating two distinct land uses that acts to soften or mitigate the effects of one land use on the other. (09 Oct 1997) |
| riparian buffer | Riparian areas that are managed to protect the aquatic and riparian ecosystem. A riparian buffer protects water quality and temperature, habitat along the banks, upland habitat for aquatic and riparian species, and some or all of the floodplain. (05 Dec 1998) |
| secondary buffer | See: Hamburger's law. (05 Mar 2000) |
| dipolar buffer | Buffer whose structure can include opposite charges. Synonym: dipolar buffer. (05 Mar 2000) |
| zwitterionic buffer | Buffer whose structure can include opposite charges. Synonym: dipolar buffer. (05 Mar 2000) |
| baseload capacity | The power output that generating equipment can continuously produce. (05 Dec 1998) |
| capacity | Power or ability to hold, retain or contain or the ability to absorb. Origin: L. Capacitas, from capere = to take (18 Nov 1997) |
| capacity factor | <physics> This is the ratio of the average power output from an electric power plant to the plant's rated capacity. A capacity factor is ideally unity, but invariably less. Capacity factors vary widely between types of electric plants (for example, nuclear, solar, coal, etc.), and can even vary widely for a single type of power plant. <radiobiology> Index (typically in percent) indicating the average power supplied by an energy plant, relative to its maximum rated capacity. Synonym: plant factor, load factor. (13 Jan 1998) |
| vectorial capacity | <epidemiology> In vector-borne infections such as malaria, the vectorial capacity is a concept analogous to the contact rate in directly-transmitted diseases. It is, thus, a function of (a) the vector's density in relation to its vertebrate host, (b) the frequency with which it takes blood meals on the host species, (c) the duration of the latent period in the vector, and (d) the vector's life expectancy. (05 Dec 1998) |
| carrying capacity | <ecology> The maximum average number or biomass of organisms that can be sustained in a habitat over the long term. Usually refers to a particular species, but can be applied to more than one. (09 Oct 1997) |
