摘要

Heat can be released or consumed in particles in a nearly adiabatic way due to phase transformation, thermal fluctuation, etc. In this case a temperature field, strongly varying in space and time, develops in the particle in addition to the global temperature field. Analytical as well as numerical solutions for this additional temperature field are presented for identical and different thermal properties of both the particle and its environment. The case of heat conduction and of heat transfer is dealt with. Consequences for nanoparticles are discussed.
