论文摘要：新疆阿尔泰海西期造山带主要发育两期区域变质作用，第一期变质作用属于区域低温动力变质作用类型，以形成低绿片岩相矿物组合为特征，变质温度较低，而应力作用较强，是造山作用初期热流活动较弱，构造变形强烈环境下的产物。

2Cm bone defect was established in ulna of rabbits, the capacity of different therapeutic measures in bone defect repairment was determined in groups A , B (implanted BMP, TGF -β〓 and carrier) and C . It was found that the appearance of osteoblasts and formation of bone union were earlier and the number of osteoblasts more in group B than in group A. The amino acid analysis revealed that the volume of ossein was significantly higher in group B than in group A at the early stage.
