摘　　要：采用最新集成芯片和软件设计 ,研制出可直接在计算机上多道同步处理的高灵敏氧分压测量仪 ,为氧分压活体检测提供了一个功能完备、方便经济的数据处理工作站。同时采用数字相关技术提高信噪比 ,得到了较满意的结果。与其它氧分压测量方法相比 ,测量仪具有检测限低、精确度高、智能化数据处理、体积小等特点。A highly sensitive multi-channel and synchronous p(o2) analysis system was developed, by using new chip and designing software with; Visual C + + and Matlab, we greatly reduce the hardware cost and provide a full function workstation that is very convenient and economic. While providing a lower cost solution, it also provides performance and space improvements. On the same time, we employ digital correlation technique to improve signal-to-noise rate, and,get satisfied results. Compared with other methods that are used to detect p(o2) the apparatus has many advantages, such as low detection limit,high precision, intelligent data processing and compact space. All these make it possible to meet higher application requirement for po(2), sensor in vivo detection and clinic research.
