Design of Assistant Instrument for Analyzing Pulse Wave Based on Blackfin
近年来,心血管疾病已经成为我国居民主要的健康杀手,而脉搏波呈现出的形状、强度、节律和速率等信息能够反映出人体心血管系统的功能状态。因此,无论在中医或西医中,检测和分析脉搏信号都是诊疗心血管疾病的重要手段。目前,脉搏诊断通常是通过大型的医疗器械来进行的,仪器存在体积大、价格昂贵等不足。针对目前脉搏诊断仪器的现状,本文设计并制作了一种便携式的脉搏波辅助分析仪。 本文所研制的脉搏波辅助分析仪,可实现脉搏信号的采集及显示,具备对脉搏信号进行频谱分析的功能,并能够计算脉搏信号的波形特量及脉搏速率。这些功能满足了一般脉搏诊断的需求。 脉搏波辅助分析仪的硬件部分由处理器电路、显示电路和脉搏信号采集电路组...Cardiovascular disease has became the primary illness to human health in China.As the pulse wave can imply a lot of informations about the human cardiovascular system,people can usually obtain the user’s cardiovascular parameters by detecting and analyzing the pulse wave signal.At present,the pulse parameters are usually obtained by the medical equipment which is large-scale and expensive.After an...学位:工学硕士院系专业:物理与机电工程学院物理学系_电磁场与微波技术学号:1982008115304

Automatic Measurement Method of the Resonant Frequency of Cylindrical Dielectric Resonator with Holes
从求解MAXWEll方程本征值出发,采用MATlAb中PdE工具箱,借助可二维作图的开槽圆柱谐振器,计算出有孔圆柱介质谐振器的谐振频率。求解结果与矢量网络分析仪测量结果吻合,误差在千分之四以内。且该有限元法计算软件采用MATlAb编写,可方便地被调用于矢量网络分析仪的VEE测试软件中,较好解决有孔及变形圆柱介质谐振器的设计、测量和微调等问题,特别是矢量网络分析仪的快速自动测量中。One method of calculating the resonant frequency of cylindrical dielectric resonant with holes is introduced.The method is based on the solution of eigenvalue of the Maxwell equation,and the resonant frequency of cylindrical dielectric resonant with holes is solved by applying the PDE tool box in the Matlab.Compared to the measurement results of the PNA,the error of the method is not more than 0.4%.The numerical method can be programmed by Matlab,and then can be applied conveniently in the test software VEE of the PNA.Thus,the complementary advantages of the method are very beneficial for the design of the resonant frequency of cylindrical dielectric resonant with holes and the deformation cylindrical dielectric resonant,and also can be used for solving many other problems,such as online automatic measurement of the resonant frequency of cylindrical dielectric resonant with holes and the deformation cylindrical dielectric resonant.福建省自然科学基金资助项目(2008J0031
