Instructor: high normalized
Abstract: This paper is to introduce the integral transform and the Laplace transform (ie Fourier transform) on solving partial differential equations, how to apply them in solving partial differential equations. Fourier transform method is used to solve the problem for determining solution of partial differential equations in unbounded region, the Laplace transform rule of thumb is used to solve the initial value problem of ordinary differential equations and equations.
Keywords: Fourier transform; Laplace transform; partial differential equations; unbounded region; definite solution of the problem.

Teacher: high whole return
Abstract: this paper is mainly introduce integral transform (namely the Fourier transform and Laplace transform) in just solve a partial differential equation, the application in solving them partial differential equations of can be applied. Fourier transform method is mainly used to solve unbounded area of partial differential equation set solutions, and Laplace transform law is used to solve differential equation and the initial value problems of systems.
Keywords: Fourier transformation, Laplace transform; Partial differential equations; Unbounded area; For solutions.
