体液及生物组织交流频谱特性测量系统

生物组织的电学性质 ,是我们认识生命物质的一个重要方面 ,对了解生命具有重要意义。但是 ,不同于非生命物质的测量 ,对生命物质的测量必须设计专门的测试电路仪器。为了更全面的了解体液及生物组织的交流频率特性 ,设计制作了一套更加符合对生命物质电特性测试的系统。系统采用了先进的测量方法、最新的专业电路和器件、以单片机为核心的测量控制、数据采集处理系统 ,使系统具有较宽的频率测量范围、阻抗测量范围、较高的测量精度和可靠性、较宽的测量适用对象、以及更智能化。另外 ,系统设计中还充分考虑了电测经生命物质带来的测量影响、在体 (invivo)和离体 (invitro)测量的时间影响等。系统在实际测量中获得了很好的实验结果 ,为生物组织电学性质的研究提供了一种更合理、更准确、更全面的手段。

A System for Testing Alternating Frequency Properties of Body Fluid and Tissues

The electric properties of biotic tissues are of importa nc e to our understanding biotic substances even life. But the measurement taken in this aspect is different from the measurement of ordinary materials, we need a special testing instrument for living substances. In order to understand the alt ernating frequency properties of body fluid and tissues in detail, we have deve loped an electricity characteristic testing system, which is more proper for tes ting living substances.This system adopts advanced measuring method and expert c ircuit. As the measure and the control core, the single chip processor is used. This system has wide frequency range and wide impedance testing range, much more adapted objects, and it is dependable, more precise and intelligent. The applic ation of this system in practical testing has obtained optimal results.
