At last, all related problems due to ship type and towing speed influencing the quality of captured images and results were discussed. A ship model with V-shape bottom and protruding keel might cause some disadvantages for PIV measurements. The use of longer laser light ducts extending deeper is a possible solution. A ship model with light yellow paint will cause the unproportionate of light and will cause white background on captured images. It is suggested to re-paint the ship model in black or dark colors to solve this problem. In high-speed test conditions, a ship model's bow waves entrain large amount of air bubbles into water and those bubbles will block the view of camera causing some random black spots in the images. Thus, it is necessary to remove the useless black spot data and repeat the same test condition if statistics requires enough number of images.

本文讨论建立此系统之技术及实验方法，设备的架置方式和配置为一可调性调整之开放式架构，质点施放方法以一自制的施放架於实验前先布置於测试段中，并制定一实验流程规范，再分别针对实验所得滑航型及排水量型船模的流线方向及切流线方向各不同位置及船速之速度进行流场分析；实验结果发现不同船型会造成不同的实验困难：船形上突起之龙骨及V形船底会遮住照明光线，可利用较深之导管调整光页角度改善；而浅色船模表面会造成光线的不均匀，可以更改船模涂装颜色改善；高速实验的气泡会不定点的遮住光线，须先除去无资料区域并使用更多资料组数来改善。

Methods: 40 cases with acute cerebral hemorrhage were divided into two groups at random,that is, the test group which have 21 cases and the control group which have 19 cases. The change of encephaledema and cephalophyma , the content of CRP and FIB,Chinese medicine symptom integral and NIHSS scores were examined in different periods after taking ningnaotang. Results: Compared with the control group, the content of CRP and FIB in the test group are obviously lower than the control group on the fourth after hemorrhage.

First, this paper presents three girders model with double cable planes which main girder and side girder is connected by rigid arms, analyzes the dynamic characteristic of Yonghe cable-stayed bridge and obtains its natural vibration modes (i.e., frequency, damping values and the mode shapes ) by ANLSIS structural analysis program and uses these parameters as dynamic dactylogram of the intact case of cable-stayed bridge. Using the passage of random as the ambient vibration ,the dynamic properties of Yonghe Bridge is measured and the modal parameter of its 15 years after is identified and used as dynamic dactylogram of the damaged case. By the finite element analysis and locale vibration test, damaged and undamaged modal parameter is analyzed and curvature mode shape, which is sensitive to damage state, is introduced as possible candidate for identifying and locating damage in the cable-stayed bridge. Selecting the branch of part measured point from modal parameter, this paper deduces the damaged index which can detect the possible damaged location of the cable-stayed bridge deck and identifies the damaged region and degree for Yonghe Bridge. For the purpose of structural condition monitoring in in-situ , from another viewpoint, this paper introduces the method called the best optimization vector to detect damaged location and degree. The accuracy and reliability of the method presented in this paper are demonstrated by static analysis and test and the healthy state of Yonghe Bridge can be evaluated.

建立了双索面通过刚臂与主梁及边梁相连的三梁式力学模型，采用ANSYS结构分析程序对永和斜拉桥进行动力分析，对其振动模态参数进行识别，以此作为斜拉桥完好状态下的动力&指纹&；采用自由交通流作为环境振源，对永和斜拉桥动力特性进行测试，识别出永和斜拉桥使用15年后的模态参数，确立了破损状态下的动力&指纹&；利用有限元分析、现场振动测试，对破损前后的模态参数进行分析，提取对破损状况较敏感的模态曲率作为斜拉桥破损诊断的参数；并从模态参数中选取部分点的分量，导出可以指示斜拉桥桥面大概损伤位置的Index损伤指标，识别出斜拉桥发生破损的区段及破损程度；考虑大型斜拉桥在线监测要求识别破损的具体位置，从另一角度提出采用最优矢量法具体确定破损发生的位置及程度；为验证本文研究成果，对永和斜拉桥进行静力分析及静力测试，对其健康状况提出可靠的评价。
