The authors are concerned with the reversible generation of heat, and the thermal and thermoelastic fields, caused by moving dislocations in an anisotropic solid with thermal conductivity. The equations governing the fields of displacement and temperature are given. They are solved by the method of Green's functions. It is shown that those fields are stated entirely in terms of the dislocation-density and flux tensors. As an example, the fields around a uniformly moving infinite straight dislocation are concerned, where the integration is carried out by means of the integral exponential functions. Numerical computations are made for the thermal fields in copper. The contours of equal temperature at a plane perpendicular to the dislocation are displayed.
