| thermal expansion | <radiobiology> Characteristic property of most solids and liquids which causes their volume to increase when they are heated. Thermal expansion and contraction can cause structural problems in pulsed fusion devices. (09 Oct 1997) |

| membrane expansion theory | That adsorption of anaesthetics into membranes so alters membrane volume and/or configuration that membrane function is affected in such a way as to produce anaesthesia. (05 Mar 2000) |
| perceptual expansion | Development of an ability to recognise and interpret sensory stimuli through associations with past similar stimuli; perceptual expansion by relaxation of defenses is a goal of psychotherapy. (05 Mar 2000) |
| clonal expansion | Production of daughter cells all arising originally from a single cell. (05 Mar 2000) |
| wax expansion | In dentistry, a method of expanding wax patterns to compensate for the shrinkage of gold during the casting process. (05 Mar 2000) |
| setting expansion | The dimensional increase that occurs concurrently with the hardening of various materials, such as plaster of Paris. (05 Mar 2000) |
| hygroscopic expansion | Expansion due to the absorption of moisture, in dental casting, the addition of water to the surface of the casting investment during setting to increase the size of the mold. (05 Mar 2000) |
| tissue expansion | Process whereby tissue adjacent to a soft tissue defect is expanded by means of a subcutaneously implanted reservoir. The procedure is used in reconstructive surgery for injuries caused by trauma, burns, or ablative surgery. (12 Dec 1998) |
| expansion | 1. The act of expanding or spreading out; the condition of being expanded; dilation; enlargement. 2. That which is expanded; expanse; extend surface; as the expansion of a sheet or of a lake; the expansion was formed of metal. "The starred expansion of the skies." (Beattie) 3. Space thought which anything is expanded; also, pure space. "Lost in expansion, void and infinite." (Blackmore) 4. Enlargement or extension of business transaction; especially, increase of the circulation of bank notes. 5. <mathematics> The developed result of an indicated operation; as, the expansion of (a + b)^2 is a^2 + 2ab + b^2. 6. The operation of steam in a cylinder after its communication with the boiler has been cut off, by which it continues to exert pressure upon the moving piston. 7. <astronomy> The enlargement of the ship mathematically from a model or drawing to the full or building size, in the process of construction. Expansion is also used adjectively, as in expansion joint, expansion gear, etc. Expansion curve, a curve the coordinates of which show the relation between the pressure and volume of expanding gas or vapor; especially. A cut-off valve, to shut off steam from the cylinder before the end of each stroke. Origin: L. Expansio: cf. F. Expansion. Source: Websters Dictionary (01 Mar 1998) |

| extensor digital expansion | A triangular tendinous aponeurosis including the tendon of the extensor digitorum centrally, interosseus tendons on each side, and a lumbrical tendon laterally. It covers the dorsal aspect of the metacarpophalangeal joint and the proximal phalanx. Synonym: dorsal hood, extensor aponeurosis, extensor expansion. (05 Mar 2000) |

|
| coefficient of thermal expansion |
A measure of how much a material will lengthen (or shorten upon cooling) based on its original length and the temperature difference it is exposed to. It becomes important when dimensions are critical or when two different materials with different CTE's are attached to each other, such as an unfilled thermoplastic and steel. Stress induced by this difference can become considerable.
