| 释义 | latent heat noun[ U ] physics specializeduk /ˈleɪ.tənt ˌhiːt/ us /ˈleɪ.tənt ˌhiːt/ the heat that is absorbed or released by a substance when it changes state, for example from a liquid to a gas, while the temperature of the substance does not change潜热（物质的形式发生变化，如从液体变为气体时，吸收或放出的热量。在此过程中，温度不发生变化。） Chemistry - general words acceptor aerosol aerosolize allotrope amphiprotic balanced equation chemical equation electrolyte endocrine disruptor endothermic epitaxial epitaxially epitaxy inorganic chemistry ionic bond nonchemical nonelectrolyte nonreactive preatomic reactive latent heat | American Dictionarylatent heat noun[ U ] us/ˈleɪ·tənt ˈhit/ physics the heat that is absorbed or released by a substance when it changes form, for example, from a liquid to a gas, while the temperature of the substance stays the same Examples of latent heatlatent heat Essential differences are that (i) systems describing the two species include reaction terms; and (ii) the latentheat is zero. This just expresses normal heat conduction with a sink term representing latentheat being taken up by melting. By increasing the surface area a t which solidification can take place, the mushy layer enhances the release of both latentheat and rejected fluid. The code handles phase changes with latentheat as well as temperaturedependent thermal conductivity and heat capacity. Aside from the latentheat of the liquid core, the chemical energy inventory is difficult to evaluate. We see that the linear profile is modified by a quadratic term due to the internal release of latentheat. When equilibrium is achieved, rising vapor will condense to liquid at the ice interface, deposit its latentheat of fusion there, and then drain as liquid. This allows crystals of the heavy component to form in the melt, lowering the composition of the melt and also heating the melt through the release of latentheat. Some is stored as latentheat in the core, and released during crystallization and growth of the inner solid core at the expense of the outer liquid core. In addition, for the low concentrations of water typically dissolved in basalt (e 0.001), the contribution of the latentheat of vaporization is negligible compared to that of solidification. An attempt to quantify the effect of partial melting was made incorporating in the model the contribution of the latentheat of melting for the metapelitic lower crust. We intend to force you to use the latentheat from your great electric plants to do useful work. From the Hansard archive Example from the Hansard archive.

From the Hansard archive Example from the Hansard archive. Contains Parliamentary information licensed under the Open Parliament Licence v3.0 Experiments indicate that the transition is second-order, meaning there is no latentheat.
