摘要：

A hyperbolic heat-conduction equation is solved for a solid of finite length at low temperatures using the Laplace transformation with the Fourier series under thermal insulation. As a result, the solution expressed with respect to both relaxation time of a high-speed thermal wave and thermal diffusivity of the solid is compared with that derived from a conventional parabolic heat-conduction equation at high temperatures.
