Methods forty patients with head/neck 16 slice CT angiograph were divided into two groups at random,each group has 20 cases, the plain scan and the CTP was performed before CTA to all 40 cases. Group A use CTP to obtain the peak time of contrasted artery as CTA delay time, and scan from head side to foot side. Group B use contrast media automatic bolus tracking to obtain delay time,scan from foot side to head side.two groups CTA images were collated.

A correlation of the experimentaldynamic response of the vessels with the theoretical finite element calculations ispresented and discussed.1 The response of the end caps is dominated by transverseand torsional deformation of the plates.The membrane strain is negligible compareto the lateral strain.2 In the lengthwise direction of the inner cylinder,themembrane strain has the same magnitude as that of the bending strain. But for theouter cylinder,the former is much smaller than the later at the same direction.3 Forboth the inner shell and the outer shell,hoop strains are primarily due to themembrane deformation.The amplitude of the circumferential flexural strain isconsiderably small.4 Peak strains in the vicinity of the connection portion of theend caps and the shells are very high.This is important to assess the safety of thecontainer in case of repeated use or tests.5 The applying load to the end cap isdifferent from that to the inner shell plate, but peak stains and nodal displacementsof these two structural parts are nearly the same.It can be inferred that the dynamicresponse of the end cap is greatly affected by the structural vibration excited by theimpulsive loading.

结果表明：1在本文所考虑的载荷水平下，平板变形以板的横向弯曲和扭曲为主，中面应变幅值比较小。2对于内容器，其纵向变形中弯曲应变和中面应变大小接近；而对于外容器，其纵向变形以弯曲为主，中面变形比较小。3内、外壳体的环向变形主要是中面应变，弯曲应变分量很小。4平板和壳体连接处应变很大，这对于多次使用或实验时评价结构安全有指导意义。5尽管内筒底板和大封头上的作用载荷有一定差别，但应变峰值和节点位移峰值基本相近，这说明脉冲载荷激发起来的结构振动对封头的动态响应有很大影响。

By using the UG top down assembly modeling technology,and optimizing the design parameters of extrusion die for pipe products,the parameters SQL database of extrusion dies was established.Microsoft Visual Studio.net 2003 MFC was chosen as the development platform of the system,and an intelligent parametric design system of extrusion dies based on UG was designed,which can automatically generate 3D extrusion die assembly parts and graphics.

Expose the nerve first at the posteromedial aspect of the distal end of the biceps femoris tendon and trace it distally to where it winds around the neck of the fibula. In this location the nerve is covered by the origin of the peroneus longus muscle. With the back of the knife blade toward the nerve, divide the thin slip of peroneus longus muscle bridging it. Then displace the nerve from its normal bed into an anterior position.

先在股二头肌腱远端后内方暴露腓总神经，顺神经向远端追踪至环绕腓骨头的部分，此处腓总神经被腓骨长肌起点覆盖，保持刀背指向腓总神经，挑断跨越神经的部分腓骨肌纤维，然后将腓总神经自正常的位置转移至前移的位置。

Atechnique of low-profile fixation using obliquely oriented screws from the radial head into the shaft has been developed to avoid distal dissection of the soft tissues and placement of hardware in an already-constrained area adjacent to the annular ligament and lateral ligamentous structures.
