With multimedia technology, audio, video and other computer-based files and materials can be edited and rearranged for specific instruction purpose to meet the diversified needs of instructors and learners.
Teachers can use the ready-made computer-aided teaching software or multimedia material library and choose the appropriate part in their own teaching; they can also use PowerPoint or some multi-media producing tools to make their own PowerPoint presentation or multimedia Courseware .
In order to ensure optimum outcome, some conditions need to be met: Firstly, the materials of appropriate level of difficulty, in which the unknown words make up a small proportion, should be chosen.

Experimental Materials.
The impact strength of samples was carried out according to ASTM D 256 in Pendulum impact testing (Zwick Material testing, August-Nagel-Str.11•D-89079 Ulm, Germany) at room temperature and tensile test was carried out according to ASTM D 638 at a crosshead speed of 50.8 mm/min with a universal tensile testing machine (LR 50k, Lloyd instruments, England).
The neat PLA fractured surface displayed a smooth and uniform surface which indicated brittle fracture behavior of polymer materials and no plastic deformation.

Tanimoto 1 Institute of Solid State Physics RAS, Chernogolovka, Russia 2 Hiroshima University, Higashi Hiroshima, Japan 3 Institute for Molecular Science, Okazaki, Japan Keywords: the Portevin-Le Chatelier effect, magnetoplastic effect, high magnetic field, relaxation of internal stresses, ion clusters, spin-dependent processes Abstract.
Direct experimental evidence of the participation of spins in MPEs [9, 10] and thermodynamic considerations developed previously in spin chemistry [11] led to a conclusion that non-equilibrium conditions are necessary to be provided for the effect of a weak MF upon physical properties of materials.
The Portevin-Le Chatelier effect is observed in many commercially important alloys, leading to heterogeneity of plastic flow and early destruction of materials, so finding of methods for suppressing of the jump-like plastic deformation is one of the practical aims of the study of the effect.

We choose PDMS (Nusil CF19-2186 and Sylgard 186) for fabricating tests samples essentially for the following reasons: not required to pre-stretch the material and can be easily bonded (plasma O2) to micromachined silicon chips.
The total thickness of this nanocomposite is usually below 100 nm (energy and material dependent, Fig. 2).
This post-polymerization electrode fabrication technique will benefit from further fundamental material studies of the nanocomposite formed by ion implantation and specific DEAP actuator developments.
