An inverse solution using Laplace transform can predict a given boundary condition well except for rapid change of the surface condition and moving heat source by introducing a time partition method. The time partition method has the ambiguity of how time is divided. A new method in which the inverse solution at a time, t, is obtained from the, measured temperatures in the time range of [t-α(L^2/απ^2), t+α(L^2/απ^2)/2] becomes free from the complicated time division. In addition, for the moving source, a new interpoltion is introduced by taking into account the temperature propagation along the moving source. The inverse solution, thereby can succeed in predicting the surface condition for any case commonly encountered. Quench cooling of high temperature, as an example of a moving source is effectively coped with.
