The CNR of fat and muscle belly on T_1WI was higher than on PDWI(p = 0.000).Conclusions:1、Routine MRI can demonstrate the dependency structure of shoulder clearly.The distance of subcoracoid was 8.84±2.97mm.The distance of sub-acromion was 5.23±1.05mm. 2、The 3D-fiesta imaging with muti-angle reconstruction is better in showing the coracohumeral ligament,coracoacromial ligament,coracoclavicular ligament, capsulolabral complex and the bone of shoulder,combing with oblique coronal and oblique sagittal imaging of the fat-suppression sequence,the diseases of shoulder can be diagnosed.

1、常规MRI能够较清楚显示肩关节相关结构，喙突下距离8.84±2.97mm，肩峰下距离5.23±1.05mm.2、3D-fiesta序列图像，应用重建功能行任意角度重建，可更好地显示喙锁韧带、喙肩韧带、喙肱韧带、盂唇-关节囊复合体及肩关节骨骼，结合斜冠位、斜矢状位的压脂序列，即可达到对肩关节疾病进行诊断的目的。

The difference among vertebrae rotational degrees measured by conimeter, Ho's method and EPPsag was compared by Wilcoxon signed rank test.

在经椎弓根中部的CT横切面上测量两侧椎弓根螺钉进钉点连线之垂直平分线与矢状面的夹角，将EPPsag角与脊椎标本的实际旋转度、Ho's法测量结果进行Wilcoxon符号秩检验。

Through the assimilating and analyzing the construction materials and the design of reinforced concrete arch bridges with long span from both domestic and abroad, the thesis studies the effect of the arch axis geometry, rise-span ratio, arch ring section and spandrel structures, as well as the ultimate bearing capacity and stability of the entire bridge on the design of reinforced concrete arch bridge. In addition, in consideration of construction, the thesis also studies the applicability of different construction methods such as cable crane system, stiffened skeleton system, swing construction system and cantilever construction system and correspoindingly economica spans and their applications of the reinforced concrete arch bridges.

本论文通过对国内外大跨径钢筋混凝土拱桥的设计、施工资料的收集及其出现问题的分析，从设计角度研究了拱轴线形、矢跨比、拱圈截面及拱上构造、全桥极限承载能力及稳定性对钢筋混凝土拱桥设计的影响；从施工角度研究了缆索吊装法、劲性骨架法、转体施工法、悬臂施工法等不同施工方法的钢筋混凝土拱桥的经济适用跨径及其适用条件。

" Diomed all undaunted answered,"Archer, you who without your bow are nothing, slanderer and seducer, if you were to be tried in single combat fighting in full armour, your bow and your arrows would serve you in little stead.

" 听罢这番话，强健的狄俄墨得斯面无惧色，厉声答道："你这耍弓弄箭的蹩脚货，卑鄙的斗士，甩着秀美的发绺，如果你敢拿起武器，和我面对面地开打，你的弓弩和纷飘的箭矢都将帮不了你的软弱。

The parameters used in the analyses include rise to span ratio, slenderness ratio, steel ratio and load conditions.

分析的参数有矢跨比、长细比、含钢率以及加载方式。

In using DGF method, the first thing is to obtain the proper form of certain area. But the DGFs obtained now are all in achiral medium. So people are eager to know DGFs in spectral domain and space domain of chiral medium.

用解析的方法求解电磁场的边值问题主要依靠建立在经典电磁场理论基础上的并矢格林函数方法，应用DGF方法首先要找出适用于相应区域中的DGF形式，而现有的DGF形式都是基于非旋波媒质情形。
