摘　　要：开发测量热敏电阻温度特性曲线硬件电路,以及成本低廉的基于虚拟仪器的锁相放大器。在此基础上研制基于计算机远程控制的热敏电阻温度特性曲线测量系统,测量结果与传统实验室进行实验的测量结果一致。A hardware circuit for the measurement of thermistor characteristic curve and a low-cost lock-in-amplifier （LIA） based on virtual instrument is successfully designed. Then the measurement system of the thermistor property curve based on computer remote control is developed. The result of remote experiment based on virtual instrument is consistent with the experiment of traditional laboratory.
