摘　　要：介绍了一种利用计算机进行PTCR阻温特性的自动数据采集及参数处理的系统,叙述了该仪器的结构及原理,详细介绍了仪器的硬件和软件。以VB为编程语言,应用于Windows98及以上版本操作系统。在界面上完成初始参数的设置,lgρ-T曲线可在界面上即时显示,并可导出数据另行处理。本系统能够方便地应用于实验室的样品测量。Measuring instrument for the resistance-temperature curve of thermistor is researched and used in lab. Describes the principle and the configuration of the PTCR resistance-temperature characteristic instrument. The hardware and software of this system are introduced. By using VB as programming language, the procedure run under the operation system of windows 98 or more. The original parameter as well as the lgρ-T relative curve were displayed on the software interface. The testing data might be extracted and saved as a format text that could be used in another data processing software. It was approved that this instrument could be used in measuring samples expediently.
