原始语种摘要: In equilibrium thermodynamics systems can be described in terms of properties which are either (1) intensive, (2) extensive, or (3) neither intensive nor extensive. While they can vary with spatial location in nonequilibrium systems, intensive properties are homogenous functions of degree (or order) zero ( k = 0) and can be measured at any point. Temperature must always be intensive, as required by the laws of thermodynamics. This fundamental aspect of temperature is preserved whether dealing with equilibrium or nonequilibrium systems, as the latter can be analyzed with local thermal equilibrium or reduced time intervals. As for extensive properties, given equilibrium, they are homogeneous functions of degree one ( k = 1) and consequently, are both additive and dependent on spatial...
