The chemical composition research aspect literature report are extremely few: According to reports, the root of Rosa davurica pall includes the lactone, the tanning substance, the return to original state sugar, the total lucoside, the flavanone, the phenol class, the biological alkalis, the protein, the anthraquinone equi com ponent, moreover ,the total polysaccharide is the even polysaccharide which is composed by the fructose.In 1999, for the first time from puncture the root in the alcohol extraction to sep arate Oleanic acid. And used the double wave length thin layer scanning method to determine the uneven pillar tartaric acid in to puncture in the root ontent.

化学成分研究方面文献报道极少：据报道，山刺玫根中含有内酯、鞣质、还原糖、总苷、黄酮、酚类、生物碱类、蛋白质、蒽醌等成分，而且山刺玫根中总多糖是由果糖组成的均多糖。1999年，首次从刺玫根的乙醇提取物中分离出齐墩果酸，并采用双波长薄层扫描法测定了齐墩果酸在刺玫根中的含量。

Methods:The 310 pedicles(in 31 vertebrae) twined with the wire of 1.0mm in diameter were taken for radiological study.The anteroposterior,lateral and superoinferior roentgenograph were performed,the relationship between the projection of pedicle screw and that of vertebrea on lateal x-ray films was investigated.

材料和方法：在31套腰椎骨标本上(310个椎弓根)用1mm软钢丝在椎弓根最狭窄处缠绕，按人字嵴顶点进针方法打入椎弓根直钢丝，拍正侧位片及横断面片，观测直钢丝在椎弓根及椎体内的位置，并推算进钉深度比率。

When packing for the valve, the valve packing section and the same space, it is best Preloading Central: When the time for the pump, valve packing and the space section (about 0.3mm-0.6mm) axis and the disk so that there is a leakage of the root space is conducive to lubrication and cooling.

当盘根用于阀门时，盘根截面和阀的空间一样，最好是预压环：当用于泵时，盘根截面和阀的空间(约0.3mm-0.6mm)使轴和盘根有一泄露间隙，有利于润滑和散热。

The plant height is 35 cm and the plant spread is 48 cm. The plume-like leaf cluster is semi-uprush with small tassel. The leaf color is deep green, but the leafstalk is light green and leave numbers per single plant are 10-12. Its fleshy root is of long column shape with rootlet, little fibre and deep green peel. The length is 26-32 cm, the diameter is 8-12 cm and the weight could reach 2-3 kg. The flesh is light green, with delicate and slight pungent taste.
