Abstract: The various order explicit schemes based on exponential fitting and Newton interpolants are constructed for partial differential equations.The various precision can be achieved by employing the various order explicit schemes.When the schemes are applied to heat transport equations at the microscale and strong transient heat transport in thin film,the effects are admirable.Numerical calculations show the present method is high accurate and computationally efficient.

Key words: The various order explicit schemes, exponential fitting, heat transport equations at the microscale, strong transient heat transport in thin film
