| Abstract: | The change of NTC thermistor with temperature was studied through the experiment,resistance-temperature curve was obtained.According to the linear relationship between the natural logarithm of NTC thermistor value and the absolute temperature,thermal index B was determined by using the least square method,and then the temperature coefficient was obtained in the temperature range of measurement. |
