Abstract: The college physical simulation experiments is an organic integration of experimental equipment,teaching content,teacher＇s guidance and learner＇s thinking.It provides a powerful way of reform for physical experiments.The students use multimedia and computer simulation technology to simulate operation,data processing and analytical thinking.Finally,they can understand and master principles and methods of experiments.But the simulation experiment has also some disadvantages.Through a typical teaching ＂thermistor temperature characteristics＂,investigating and analyzing for the simulation experiment,it is obtained some negative effects in the experimental teaching process.Some issues of attention are proposed for the reform of university physics experiments.

Key words: physical simulation experiments, thermistor, temperature characteristics
