For these biomaterials, it is considered really suitable that they must be absorbed at the same rate at which bone is regenerated. [1] In order to decrease antigenicity and improve mechanical properties, collagen was cross-linked with glutaraldehyde (GA) by reaction of ε-amino group of lysine (Lys) and hydroxylysine (hyl) present on the collagen to form Schiff base type cross-links.[2] Materials e Methods Extraction of collagen and preparation of samples Bovine tendon was cleaned and cut into pieces of 1cm².

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
