During the operation, a drill, 4.5 mm diameter, was used to drill a hole on the lateral ankle; one anchor was drilled into the talus at the end of anterior talofibular ligament, another one was threaded on the calcaneus; the allogeneic tendon was permeated through the hole on the lateral ankle, maintaining ankle neutral and moderate valgus position.

Analyzing the model, especially the activity of Taihang Mountain piedmont fault, we got such main conclusion:1. Based on sequence stratigraphy, the strata is divided from the selected drills. And the Quaternary stratigraphic framework of Handan city is established, dividing the Quaternary strata into four parts- Qh, Qp3O , Qp2Y and Qp1G.2. With all the selected drill data of Handan city, a drill database is established. A quaternary strata 3D model of Handan city is imitated by GOCAD and ArcGIS, and so are the bottom structural map of each horizon.3. Analyzing the 3D model and the contradistinction section of drills, we got: the stratum of Qh and Qp3 is smooth and flat, with a feature of a higher west, little difference between south and north and undistinctness of faults; there are several depocenters along S-N and N-W in the stratum of Qp2, and the evolution of the stratum is controlled by a couple of ruptures, which means the tectonic movement is active in this period of time.4. Since quaternary, main tectonic movements happened in Qp2 and have been stable in Qp3 and Qh.

获得主要结论如下：1、利用层序地层学的方法将收集的邯郸市钻孔以及论文所依托项目野外施工的钻孔进行了具体的地层划分与对比，建立了邯郸市第四系等时地层格架，将邯郸市第四系划分为全新统、更新统上部欧庄组(Qp3O)、更新统中部杨柳青组(Qp2Y)和更新统下部固安组(Qp1G)。2、利用收集到的邯郸市水文、工勘钻孔以及所依托项目初勘和详勘两个阶段野外施工的钻孔数据，建立钻孔数据库，通过使用三维建模软件GOCAD和地理信息系统软件ArcGIS等进行模拟，得到邯郸市市区部分第四系地层三维可视化模型，并获得各个地层的底部构造图；3、通过对所天生模型和钻孔廊带对比剖面的分析，可以得到：全新世和更新世晚期(Qp3)时期地形整体较平缓，整体上显示西高东低、南北差异不大的格式，断裂显示不明显；更新世中期(Qp2)时期沿南北向和北西向存在几个沉积中心，地层发育受几条断裂的控制，反映了研究区的构造活动在更新世中期较为活跃；4、邯郸市自第四系以来，主要构造运动均发生于更新世中期，到更新世晚期及全新世时期逐渐趋于稳定，进而使更新统上部和全新统地层沉积均一且完好。

The enthusiasm are kept within limits because of insufficient expense investment; the rare chances for the coaches to exchange with their opponents and the poor ability of their scientific research makes them focus too much on the practical drill and rely on the experiential drill; the poor technical and ideological quality of the umpires are mainly to blame for unjustness of judgment.

由于经费投入不足等原因遏制了基层培养跆拳道后备人才的积极性；教练员外交流机会少，对运动训练全过程仍只抓训练实践活动本身，科研能力不强，经验训练占很大比例；跆拳道比赛存在裁判不公的现象，裁判技术、思想作风是造成裁判不公的主要原因；没有建立人才储备机制，大量17岁以后可以出成绩的运动员流失社会：基层运动员的学习质量无法保证，造成了运动员无法提高技术水平、就业困难等问题。

The inclined capacity of BHA is analyzed, which is affected by various parameters. It is shown that the lateral force of drill bit and inclined capacity of BHA have something to do with the parameters(the distance between drill bit and the first stabilizer, outside diameter of the first stabilizer, WOB etc).

分析影响常用钻具井斜性能的因素，得到了近钻头稳定器与钻头间距变化、稳定器工作外径变化、钻压变化等能够改变钻具井斜性能；同时以一组双稳定器钻具组合为例，分析钻具节点的位移变化图、弯矩图和应力分布图可得出钻具上的受力变形情况。
