In order to understand the effect of these materials, test LED samples were prepared with different sets of packaging materials.
As a very important part of LED compositions, packaging materials are sensitive to high temperature.
Thus, the failure of packaging materials is one of the most important reasons of lifetime reduction of the whole LED models.
In order to discover the failure behavior and principle of packaging materials, some typical samples which were the LED modules with common packaging materials including phosphor and silicone were used to undertake high temperature aging test.
By the means of measuring the luminance of samples online, the failure process of packaging materials had been revealed.

Keywords: Airport noise, building material composition, STL reduction.
The development of the airport always causes the noise impact to the surrounding environment.1 Housing close to the airport will be annoyed by the aircraft noise, especially if the building is not added by absorber building materials.
The decrease of the noise level found out from the research is caused by the value of Sound Transmission Loss (STL) of the building materials composition.
In some journals that I wrote that the building models are not assumed to be a single model.

Abstract.
This paper illustrated the Safety levels in the Chinese Construction Materials Industry (CMMI) during the Twelfth Five-Year Plan.
Introduction CCMI is one of the most important basic raw materials industries in China and plays an important role in the national economy.
Half of the world totals of these materials are produced by or consumed in China(Nesadurai,2005).
Moreover, the quantity and quality of Chinese new wall materials, glass fiber products, glass deep processing products, FRP products, and cement products has also improved significantly.
