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。

Casethat begin transformation but do not become embedded in the baroclinic zone fail to complrte transformation and simply dissipate over lower sea surface temperatures.1at transformation stage,there are two features in 500mb analysis aKOPPU s surface center is located beneath concentric,closed 500mb contours and is equatorward of 5820-m contour associated with a short-wave trough to the northwest of strom bthe closed contours associated with KOPPU 24h earlier have combined with approaching 500mb trough so that KOPPU appear to be in an open wave.furthermore,streamlines associated with this short wave trough have wrapped around the circulation of KOPPU,which indicated that KOPPU has become embedded in 500mb westerlies.

台风变性分为两个阶段：变性阶段和再加强阶段；变性的开始和结束以热带气旋环流和先前存在的中纬度斜压带相互作用为基础，KOPPU嵌入先前存在的中纬度斜压带且风暴中心在冷下沉气流中，而KETSANA没有嵌入先前存在的中纬度斜压带则没完成变性只是消散在低的海平面温度(1)台风变性阶段在500hPa高度场分析中有两个重要特征：a首先风暴中心是闭合的等值线并和风暴中心西北的短波槽相关；随后闭合等值线靠近500hPa槽，因此风暴闭合中心消失，风暴位于开波中。b而且和短波槽相关流线缠绕在风暴中心，结果风暴在西风带中。
