| 설명 | 수은과 다른 금속과의 합금. 수은의 양이 많으면 액체 상태가 되나, 대부분은 고체 상태이다. 수은은 백금, 철, 니켈, 망간, 코발트 따위의 녹는점이 높은 몇 가지의 금속을 제외하고는 여러 실용 금속과 서로 녹아 아말감이 된다. 금과 은의 야금, 거울의 반사면, 치과용 충전재 따위로 쓴다. 치과용 아말감 합금을 수은과 빚으면 가소성이 있는 점토와 같은 것이 얻어진다. 이것은 시간의 경과와 함께 약 24시간에 경화된다. 이 때문에 어떠한 와동에도 충전할 수 있고 또한 시멘트라인이 전혀 없기 때문에 시멘트의 용해로 인한 변연 유리라든가 접합물 이탈이라는 현상은 일어나지 않는다. 아말감 합금으로서 은-주석계인 것과 은-주석-구리계의 2종이 있다. |

| condenser or condenser lens | <physics> A term applied to lenses or mirrors designed to collect, control, and concentrate radiation in an illumination system. (05 Aug 1998) |
|---|---|
| amalgam | <dentistry> A soft metal which results from an alloy of a metal with mercury. Commonly used as a silver-tin or copper alloy in dentistry for fillings. (08 Jan 1998) |
| amalgam carrier | An instrument used to transport triturated amalgam to a cavity preparation and to deposit it therein. (05 Mar 2000) |
| amalgam matrix | A device used during placement of the amalgam mass within a compound cavity preparation, facilitating proper condensation and contour thereof by providing a confining wall. (05 Mar 2000) |
| amalgam strip | A linen strip without abrasive used to smooth proximal contours of newly placed amalgam restorations. (05 Mar 2000) |
| amalgam tattoo | A bluish-black or gray macular lesion of the oral mucous membrane caused by accidental implantation of silver amalgam into the tissue during tooth restoration or extraction. (05 Mar 2000) |
| pin amalgam | An amalgam restoration held in place largely by small metal rods protruding from holes drilled into tooth structure. (05 Mar 2000) |
| spherical amalgam | An alloy for dental amalgam composed of spherical particles instead of filings. (05 Mar 2000) |
| dental amalgam | <chemical, dentistry> An alloy used in restorative dentistry that contains mercury, silver, tin, copper, and possibly zinc. Chemical name: Dental materials and fillings, amalgams (12 Dec 1998) |
| Abbe's condenser | A system of two or three wide-angle, achromatic, convex and planoconvex lenses that may be moved upward or downward beneath the stage of a microscope, thereby regulating the concentration of light (directly from a bulb or reflected from a mirror) that passes through the material to be examined on the stage. (05 Mar 2000) |
| achromatic aplanatic condenser | <microscopy> A well-corrected microscope condenser lens, corrected for chromatic and spherical aberrations and satisfying the sine condition. (05 Aug 1998) |
| automatic condenser | A mechanically or electrically activated device used to provide condensing pressure in the placement of amalgam or gold foil in a cavity preparation. Synonym: automatic condenser. (05 Mar 2000) |
| cardioid condenser | A type of dark-field condenser. (05 Mar 2000) |
| cardioid dark field condenser | <microscopy> A condenser designed with two reflecting surfaces, the first, a spherical surface which reflects the rays to a second, cardioid (heart-shaped) surface. The virtue in such an arrangement is that, if the cardioid surface is of true figure, the lens is both achromatic and aplanatic. It has a limiting numerical aperture of about 1.0. Thus objectives of a greater numerical aperture cannot be used successfully with it. A true cardioid figure is the trace of a point on the circumference of a circle rolling around an equal, fixed circle. (05 Aug 1998) |
| paraboloid condenser | A type of dark-field condenser. (05 Mar 2000) |
