摘要
The image systems for the disturbance temperature fields in and outside an isolated ellipsoid driven by an n-th order ambient field are introduced and their connection to the ellipsoidal harmonics is derived. More general ambient fields may be handled by superposition of these basic solutions. These result have been used to derive the Faxén relation for the arbitrary n-th order multipole moment. The explicit expressions for the temperature fields and the thermal moment tensors for an ellipsoid in linear and quadratic ambient fields are given to illustrate the method. © 1987 Martinus Nijhoff Publishers.
