In order to study the thermal dissipation, the temperature change during low cycle fatigue was measured by a kind of small thermistor.

An advanced infrared camera was also used to record specimen temperatures, results show temperature evolution of fatigue specimen depends on the material type and loading level, the temperature increased sharply just at the beginning of the test, which is correspondent to the thermal dissipation in the specimen.

The affects of crystal absorption for heat radiation on crystal growth,which include:the heat loss of the hot grower,the chara cteristic of temperature time of crystal growth,the pattern of fluid flow and the shape of interface,the interface inversion of crystal,the temperature distribution and the thermal stress distribution,are reviewed in this paper.
