and the microbes have the function of nitrogen fixation and provide nutrients to plants, and change the characteristics of the soil,so it makes nutrient cycling imperfect  , plant live difficult.In Coal fire area ,the vegetation is sparse and biological degradation.Surface temperature directly killed a large area of the vegetation and the forest and grassland near the fire area fired, a wide range of surface vegetation damaged. coal fire area in WenSu xinjiang, China, in accordance with the ridge surface formed in 500 ~ 1000 m long, 200 ~ 300 m large wide fire area,  surface radiation temperature as high as 270 ℃, pieces grass and trees die. [4] By the end of 2008, forty-nine burning coal fire area caused about 7.8 million m2 pasture was destroyed.queergou,hutubi,xinjiang coal fire area tens of thousands  square meters of forest have destruction, on  vegetation. the ground .Falls off near the poplar leaf blight, leaf poisoning substance benzopyrene content is 130 times more than normal materials

Degradation of methanol yellow is one of the research projects using photocatalyst materials.
Experimental Materials.
Some materials with a technical grade, such as HCl, NaOH, metanil yellow (C18H14N3O3SNa), and deionized water.
Because the amount of Ag dopant used is likewise very low compared to other materials, the element Ag has the lowest proportion.

This causes rapid CT blade material degradation resulting in premature failures which are challenging to predict.
Material properties captured in Table 1 were then assigned to elements.
Heat transfer by convection causes differential temperature distribution which results to induction of thermal stresses on the material as illustrated in Fig. 4.
(8) Where is the creep strain rate, is the stress in (MPa), is creep strain, is time in (hours), is temperature in (), , , are material constants.

New materials such as ultra-high performance fibre concrete (UHPFC) could be cost-effective structuralengineering solutions.
In Australia, an example of this material available commercially is Ductal® by VSL.
The excellent mechanical characteristics and high density of UHPFC (Fig.1) make it an ideal material for resisting blast effects.
