Some teachers believe that although multimedia teaching represents an advanced education concept, totally replacing blackboard writing by computers is against the cognitive regulation and teaching theory.
Summary It is a complicated systematic engineering to building an evaluation system for multimedia teaching, meanwhile, which is an entire new research project of modern education and teaching domain.

Introduction A number of thermo-mechanical processes have emerged recently and often results in superior mechanical properties of advanced materials [1].
However, the change of material states under the thermo-mechanical deformation has rarely been reported, though it is one of the most important areas in materials science and engineering.
