综述了热效应研究的最新进展。磁场、静液压力、单轴应力和电场等外部刺激分别产生磁热效应、气压效应、弹性效应和电热效应。对所选材料编制了等温熵和绝热温度变化等相关量的数值。当材料处于相变附近时，这些量的值较大。不同自由度之间往往存在耦合，材料对不同的外场可能表现出交叉响应。在这种情况下，当施加电场时，材料可以表现出常规或反热效应。在中等电场中，许多热效应的报告值足够大，足以设想这些材料在高效和环境友好型制冷中的未来应用。
Recent progress on caloric effects are reviewed. The application of external stimuli such as magnetic field, hydrostatic pressure, uniaxial stress and electric field give rise respectively to magnetocaloric, barocaloric, elastocaloric and electrocaloric effects. The values of the relevant quantities such as isothermal entropy and adiabatic temperature-changes are compiled for selected materials. Large values for these quantities are found when the material is in the vicinity of a phase transition. Quite often there is coupling between different degrees of freedom, and the material can exhibit cross-response to different external fields. In this case, the material can exhibit either conventional or inverse caloric effects when a field is applied. The values reported for the many caloric effects at moderate fields are large enough to envisage future application of these materials in efficient and environmental friendly refrigeration.
