Procure normal 3D finite element model of acetabulum by adding mechanics parameter to the haunch bone model with Ansys software.

正常髋臼及不同面积后壁骨折条件下应力分布情况按设定骨折线在模型上将髋臼后壁进行拆分后获得髋臼后壁1／3、2／3、3／3骨折的三维可视模型和有限元网格模型。

Modify the model by FreeForm software and dissecte the model of haunch bone; import the 3D visible model of haunch bone into Ansys8.0 software. Add mechanics parameter to the haunch bone model, construct 3D finite element model of acetabulum. 2、On the base of common fracture line of acetabular posterior wall fracture in clinical cases, split the acetabular 3D finite element model according to 1/3, 2/3, 3/3 areas fractures of posterior wall after simplify setting, obtain four types of acetabular posterior wall fracture model(including normal condition of acetabulum).

按髋臼骨折Letournel分类标准并根据临床髋臼后壁骨折病例常见骨折线位置，进行简化设定，依次按后壁1／3，2／3，3／3面积骨折将髋臼三维有限元模型后壁进行拆分，获得三种髋臼后壁骨折状态的有限元模型；再模拟双足直立位对髋骨约束设定，分别对后壁正常及不同面积骨折状态模型进行加载，获取各模型应力分布图并记录臼顶负重区、髋臼前壁和剩余后壁在不同后壁骨折状态下应力分布大小及改变。

During my early years of operating acetabular fractures I was assisted for the first time by my chief, Gus Sarmiento on a Kocher-Langenbeck approach to a transverse plus posterior wall fracture.

在我做髋臼骨折的早期，第一次是有我主任Gus Sarmiento帮助我采用Kocher-Langenbeck入路完成一例后壁+横行骨折病例。

The model had good duplicability and stability through the method of establishing the animal model in which the simple operative method,small wound and convenient nurse was obtained so easilyis that the animal model was spread easily.The study of the change of short and long period was made to provide the experimental base and reason through the animal model.

结论通过自制冲击器冲击兔右侧髋臼软骨，模拟冲击伤机制，初步建立髋臼软骨冲击伤实验动物模型并量化冲击能，通过统计学分析，大体和组织病理学检查，并与国外动物模型相比，本模型重复性和稳定性好，术式操作简单，创伤小，护理方便，易于推广，为研究活体动物髋臼软骨冲击后的短期和长期变化提供实验基础和依据。

Grouping lesional and homeochronous normal hip to pair, dynamic measuring AI and AI in each age groups of lesional and normal hip on before reduction、after reduction 3rd month、6th month、9th month、12th month, describing the characteristics of acetabular development in each age groups on every observation time-points, comparing the difference of lesional acetabular development with normal acetabular physiological development.

并以患侧髋关节与同期健侧髋关节进行配对分组，动态测量各年龄组患儿患、健侧髋关节在复位前、复位后第3、6、9和12个月时的髋臼指数和髋臼深度与宽度比值AI(D/W，描述各年龄组在各时间观察点上髋臼发育的特点，比较患侧髋臼发育与健侧髋臼生理发育的差异。

Methods From Jan. 2002 to May 2008,32 patients with acetabular fractures were treated with pelvic reconstruction plates and absorbable screws.Single or combined ilioinguinal,or Kocher-Langenbeck approaches were adopted,depending on the fracture classification of the all patients.

对2002年1月至2008年5月采用重建钢板和可吸收螺钉治疗的32例髋臼骨折患者进行回顾性分析，根据骨折类型分别采用单一或联合髂腹股沟入路、髋臼后侧入路

Objective To study the best entry points, direction and length of screw in acetabular posterior column plate technique, and to prevent the serious complications of screw penetrating the joint surface.

目的 研究髋臼后柱钢板内固定技术中螺钉的最佳进钉点、方向和长度，预防发生螺钉穿入关节内的严重并发症。

Finally, according to market conditions and market products this article paper analyzes the trends in the development of camera technology, and designs a color night vision camera.

最后根据市场情况和市面上产品的情况分析了摄像机技术的发展趋势，并设计了一款彩色夜视摄像机。

Only person height weeds and the fierce looks stone idles were there.

只有半人深的荒草和龇牙咧嘴的神像。
