　　Reduced Graphene Oxide (RGO) film has been prepared.The Temperature Coefficient of Resistance ( TCR) of RGO in different process parameters (Ultrasonic time,film thickness.solution concentration,and heat treatment temperature are studied and the best parameters which are ultrasonic time of 14 hours,film thickness of 0.12 mL and heat treatment temperature of 800 0C are given through the calculated TCR value in this paper.The result of experiment is that TCR value of RGO ranges from -0.67 ％ to -1.36 % and the maximum difference TCR value of each situation is 0.49.
