| 摘 要： | 基于惠斯通非平衡电桥的热敏电阻温度计,其电压—温度的关系是非线性的。在此基础上利用运算放大电路,通过选择合适的电路参数可以使电压与温度的关系线性化。实验结果与利用计算程序软件得到电压—温度特性的理论值非常接近。

| Abstract: | The relation of voltage and temperature for thermistor-thermometer based on Wheatstone bridge is non-linear. Operation magnifying electrocircuit is used and appropriate electrocircuit parame- ters are chosen to make the relation of voltage and temperature linearization. The experimental result of the relation of voltage and temperature is close to the data in theory form compute procedure. |
