| 설명 | 심장의 수술에 사용되는 기계로서 심장이 수술을 받고 있는 동안 기능을 하지 못하므로 이 기능을 대신 해주는 기계이다. 이것은 대정맥과 대동맥사이에 연결이 되어서 혈액을 강제로 순환시키면서 대정맥에서 온 피에 산소를 공급하여 대동맥으로 돌려 보내는 역할을 한다. 즉 심장과 폐의 역할을 동시에 하는 기계이다. |

|---|---|---|---|
| 설명 | 심장의 원래 기능, 즉 혈액을 말초로 보내는 펌프와 같은 기능이 거의 없어진 상태를 말한다. 피를 보내는 펌프의 역할이 멈추었으므로 심장으로 들어오는 피는 심장으로 들어오지 못하고 정맥속에서 정체하게 된다. 그리하여 혈액의 대부분이 말초의 정맥에 머물게 되어 여러 가지 증상이 나타난다. 특히 허파를 돌아 좌심방으로 들어가야하는 피가 펌프 기능이 없어져서 왼심방에 많은 피가 정체하고 있어서 들어가지 못해서 허파에 고이게 된다. 그러면 허파에 산소와 이산화탄소를 교환하는 기능이 없어져서 숨을 쉬지 못하는 결과를 낸다. 즉 숨이 차고 숨쉬기 힘든 증세가 나타난다. 또 온몸을 순환한 다음에 우심방으로 들어와야하는 피도 우심방으로 들어오지 못해서 말초에 정체하므로 온몸이 붓게 된다. |

| van't Hoff's law | In stereochemistry, all optically active substances have one or more multivalent atoms united to four different atoms or radicals so as to form in space an unsymmetrical arrangement, the osmotic pressure exerted by any substance in very dilute solution is the same that it would exert if present as gas in the same volume as that of the solution; or, at constant temperature, the osmotic pressure of dilute solutions is proportional to the concentration (number of molecules) of the dissolved substance; i.e., the osmotic pressure, π, in dilute solutions is π = RTσci, where R is the universal gas constant, T is the absolute temperature, and ci is the molar concentration of solute i, the rate of chemical reactions increases between two-and three-fold for each 10캜 rise in temperature.

| reciprocity law | In two photochemical reactions, e.g., the darkening of a photographic plate or film, if the product of the intensity of illumination and the time of exposure are equal, the quantities of chemical material undergoing change will be equal; the retina for short periods of exposure obeys this law. Synonym: reciprocity law, Roscoe-Bunsen law. (05 Mar 2000) |
