| thermal capacity | <chemistry> The amount of energy required to raise the temperature of an object by one degree Celsius (or Kelvin), it is represented by the symbol C and is given in units of J/K. (09 Jan 1998) |
|---|---|
| thermal conductivity | <radiobiology> Degree to which a substance transmits heat. (basic definition, I believe, is: (heat flow) = (thermal conductivity) (temperature gradient)) (09 Oct 1997) |
| thermal conversion cycle | <radiobiology> Process of generating electrical power with a fusion reactor by means of a steam / other gas turbine. This is distinct from direct conversion cycles. (09 Oct 1997) |
| thermal cover | Vegetative condition, generally with greater than 70% canopy closure and 40 feet in height, that can significantly ameliorate weather effects such as wind, heat, cold, and snow. Used by wildlife in winter. (05 Dec 1998) |
| thermal efficiency | <radiobiology> Ratio of the electric power produced by a power plant to the original amount of heat produced. This measures the efficiency with which the thermal energy is converted to electricity. (09 Oct 1997) |
| 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) |
| thermal melting profile | In general a record of the phase state of a system over a temperature range. Phase changes can be detected by exothermy or endothermy. Valuable in studying lipid and DNA structures. (18 Nov 1997) |
| thermal neutron | <radiobiology> A neutron in thermal equilibrium with its surrounding environment. Thermal neutrons are those that have been slowed down by a moderator to speeds characteristic of the local temperature. Compare: fast neutron. (09 Oct 1997) |
| thermal resource | A facility that produces electricity by using a heat engine to power an electric generator. The heat may be supplied by the combustion of coal, oil, natural gas, biomass, or other fuels, including nuclear fission, solar, or geothermal resources. (05 Dec 1998) |
| thermal sense | The ability to distinguish differences of temperature. Synonym: temperature sense, thermal sense, thermic sense, thermesthesia. Origin: thermo-+ G. Aisthesis, sensation (05 Mar 2000) |
| thermal sensors | Sensors that detect tiny changes in heat or temperature. (14 Nov 1997) |
| thermal spectrum | The part of the invisible spectrum of wave length just longer than that of visible red light. Synonym: thermal spectrum. (05 Mar 2000) |
| thermal velocity | <radiobiology> Average speed (magnitude of velocity) of a particle at a given temperature (in a Maxwellian velocity distribution). (09 Oct 1997) |
| active length-tension curve | The relationship between active isometric tension and preload (rest length) for a contracting muscle. (05 Mar 2000) |
| alignment curve | The line passing through the centre of the teeth laterally in the direction of the curve of the dental arch. (05 Mar 2000) |
