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。

Arteriosclerosis has a huge influence on human's health. Currently the diagnosis of arteriosclerosis is based on invasive cardiac catheter measurement, but this method could cause subject's great inconvenience and might be dangerous. In this regard, this paper proposes a non-invasive pulse characteristic points locating system for arteriosclerotic degree examination. The pulse characteristic points we use include pacemaker, percussion wave peak, dicrotic notch and dicrotic wave peak. From the pulse characteristic points, we can calculate the arteriosclerotic degree examination parameters, such as pulse wave velocity, stiffness index and reflection index, etc. Those parameters can be used for diagnosing the degree of arteriosclerosis.

动脉硬化对於人体健康有极大的影响，然而目前动脉硬化的诊断主要在於侵入式的心导管量测，容易造成受测者的诸多不便及危险性；有鉴於此，本论文系设计一应用於动脉硬化程度检测之脉波特徵点定位系统，如：起搏点、主波峰顶点、重搏切迹与重搏波顶点等，经由准确的脉波特徵点定位计算出脉波传导速率、硬化指数与反弹指数等动脉硬化程度检测参数，透过这些数据，可提供医师在诊断动脉硬化程度上的辅助。

Secondly, the more complex inner and outer flow field is simulated around axisymmetric body with pump-jet (including no tip-clearance flow) with stator and rotor, and the numerical results are approved reasonable and inerratic by the contrast of the thrust and torque of rotor and stator to the experiment under the unself-propelled and self-propelled conditions.

紧接着，分析了推进器在非自航状态和自航状态下的性能、导管内部轴向、径向和周向速度场、压力场在相互作用中的具体形态和结构，并定性地分析了它们对水动力噪声、空泡生成以及振动的影响，为减少这些不利影响明确了解决的办法，为泵喷推进器的工程设计提供了切实可行的理论分析方法和技术思想，对工程实际具有重要的指导作用。

Using an epidural catheter placed at the level of T1-2 or T2-3, seven patients scheduled for awake CABG received TEA for total arterial myocardial revascularization after partial lower sternotomy.Six patients remained awake and spontaneously breathing during the entire procedure, but one required intraoperative intubation for respiratory distress caused by phrenic nerve palsy. Hemodynamics were stable throughout surgery without significant arterial hypercarbia. All patients rated TEA as "good" or "excellent."
