Using the one-dimensional unsteady heat conduction integral equation, a transient time-keeping method for determining the thermal conductivity of the material is proposed, which significantly improves the testing speed and testing accuracy compared with the steady-state and quasi-steady state methods. The results show that the method can be effectively used to determine the thermal conductivity of most materials
