Abstract］ objective to explore the accuracy and safety of safety drillprepared for cervical pedicle screw trajectory.methods fourteen adult cadaver specimens of cervical spine（c3～c7）with intact structures including ligaments and perivertebral muscles were reserved and used.according to the radiographic measurements,safety drill was inserted into cervical pedicle individually.the evaluation of the drill's trajectory was carried out by ct scan and three-dimension reconstruction and autopsy.results one hundred and forty drill's trajectories were made.9 holes failed with a perforation rate of 6.4%.conclusion the safety drill prepared for cervical pedicle screw hole is safe and effective and can be applied and popularized clinically.

目的 探索安全钻头应用于颈椎弓根螺钉孔道钻探的安全性与准确性。方法随机取14具福尔马林浸泡的成人颈椎标本（c3～c7），保留完整的脊柱三柱结构及相关的韧带和椎旁肌，根据影像学测量的进钉点和进钉方向，模拟颈椎后路手术过程。选用安全钻头，进行实际的颈椎弓根螺钉孔道的钻探，将孔道行ct扫描，并斜位三维重建孔道形态，并以肉眼直视观察结果为金标准，评价孔道钻探的成败。结果钻探孔道准确率89.3%（125/140），穿孔率6.4%（9/140）。结论安全钻头应用于颈椎弓根螺钉孔道钻探的安全性与准确性均较高，可以在临床上推广使用。

The mechanism of action maybe include the depression in content of collagen, inhibition to proliferation of lung fibroblast, action of anti free redical and anti lipid peroxidation, and elevation of content of GSH-PX.So we think phenol total base of plumula nelumbinis is a sort of promising drug to healing PF.

综上所述，我们认为莲子心酚性总碱可能对肺纤维化的病理过程有多靶点作用：前期通过抗自由基作用，从而减轻肺泡炎损伤：后期直接抑制肺成纤维细胞的增殖及蛋白沉积，减轻纤维化病变程度。

Utilizing interactive TOPSIS, the prepotent information of load points can be effectively extracted, thus the subjectivity and blindness during the decision-making process can be avoided, and then the allocation of the investment to mitigate voltage sag could be allocated more reasonably.

交互式TOPSIS方法的运用能够有效地提取负荷点的优势信息，避免了决策过程中的主观性和盲目性，使电压暂降投资的分配结果更加合理。

Based on the analysis of similarities and differences between core data, well log and seismic prospecting, the thesis makes a primary match between them;(2) Through layer boundary dividing by Walsh transformation, lithology determination by gray system and stratigraphy correlation by dynamic waveform match, an application to the aimed area was done;(3) This paper also gives the research on the character of well logs and reservoir parameters. According to the FBM protype, the profile of density and acoustic value between two wells was built. And the result showed good accordance with real logs.(4) By means of fractal reconstruction, it rebuilt the three dimensional shapes of the main stratigraphy boundaries in the studied area.

在详细分析总结岩心、测井和地震数据异同点的基础上，对三种数据进行了初步的匹配；②通过对测井曲线的沃尔什变换分层、灰色关联法岩性判别，综合多种动态层序对比技术，增改对比过程所需要的参数，进行了井间地层对比方法的探讨与应用研究；③详细研究了测井曲线以及储层参数分布的分形特征，以分数布朗运动为原型模拟出两口井中间对应地层的密度和时差参数剖面，结果与验证井数据表现出了良好的一致性；④采用分维重建方法再现了研究区块泉头组顶底面以及登二段底面的空间形态。

This results indicated that peashrub shrubland created a favorable N condition for its invading the meadow and being invaded by birch forest, and played a important role in altering the successional direction of meadow→peashrub shrub land →birch forest.

尽管箭叶锦鸡儿灌丛植物叶片与凋落物中全N、全P浓度在大多数取样点上都低于硕桦，但表层土中全N浓度高于硕桦和草甸，且其土壤有机质的供氮能力以及维持氮素能力都高于硕桦林和草甸，表明，锦鸡儿灌丛为侵入草甸和硕桦入侵提供了良好的养分条件，在该演替序列的发展过程中起了一定的推动作用。

Using nearly 50 years of landuse classification map of urban center in Shanghai city as data resources,the gross variation of landuse is studied by using GIS technology.Suppotred by GIS,the status transfer matrix of different landuse classification of adjacent period of time is also calculated respectively by this paper.At last,the spatial evolving process of landuse of urban center in Shanghai city is analyzed simulatively and forcasted quantitatively by using Markov model.
