The linear isotropic material modal was selected during the analysis.
The material modal is the same with VD furnace body material modal.
We get eigenvalue buckling mode’s 1% as initial defect, and consider material’s nonlinearity, furnace cover’s material model is the same with furnace body.

Therefore, this sudy attempts to state the advanced science and technology material----fiber reinforced composites introduced into Wushu equipment to push forward traditional Wushu scientific and standardization. 1 The necessity and feasibility of advanced materials introduced into Wushu equipment Wushu equipment mainly includes instruments, clothing, protective gear, target and site facilities,etc.
Advanced materials can improve the adaptability of Wushu devices.
On the other hand, the use of advanced materials plays an important part in Wushu competition.
So research and development on new materials used in sports need to strengthen [2] .
As for the Wushu sports equipment, the research into the use of new materials is even missing.

Since QDs are bright, light stability and have a broad excitation spectrum corresponding a narrow emission spectrum which controlled by the size and the composition of the material.
The starting materials were Zn(Ac)2 , Cu(Ac)2 , deionized water and Na2S,all the reagents used were analytical grade without further purification.
