The rice husk ash is used as the natural raw materials instead of commercial SiO2.
Introduction Bioactive materials have concerned for clinical application because of their excellent osteoconductive and bioactive properties.
Experimental Materials preparation The silica powder (SiO2) was derived from the extracted rice husk.

Study on Energy Materials with Energy Level Width of 2DEG in Triangular Well Gang Xu1, a, Yue Sun2,b 1College of Physics and Electronic Engineering Chongqing There Gorges College Wan Zhou China 2 College of Physics and Electronic Engineering Chongqing There Gorges College Wan Zhou China axugang1978@tom.com, bsunyue@tom.com Keywords: 2DEG; Energy level width; Triangular well; Energy Materials.
Abstract: Applying theories on quasi-classical particles and the uncertainty relation of quantum mechanics, we deduce the formula of energy uncertainty in energy materials with electric field .We use it to two dimension electron gas (2DEG) in triangular well and get its energy width.
So we could consider the electric field lead to broaden of energy the width of energy levels in energy materials.
At the same time, the energy width of the first excited state is wider than the ground state in energy materials, At the same time, the result of this paper is agreement with the experiment [1,5].

Third, they should find additional materials to support the teaching materials and get students interested.
Therefore, the teachers’ skill in “enriching teaching materials” needs to be improved quickly.
For instance, the Core English of Shanghai Jiao Tong University and the English reading materials included in “Construction Plan of Network-based Remote Teaching System in the New Century” recommended by the State Council are excellent teaching materials.
The contents of all-English teaching materials vary according to different majors.
