摘　　要：用有限差分法对热印头发热电阻（热阻）的温度场进行了理论计算，得到了对热阻通电与不通电两种状态下热阻的温度场．采用红外热像仪及配套系统对其进行了测试，实验结果与理论计算结果吻合良好．The temperature field for the heating resistor of 1111 and 1000 (1 represents the Heating Resistor being heated, 0—not heated) by calculating the temperature of the heating resistor of the thermal printer head using the finite difference method. Also, experiments have been performed using the service of infrared thermovision AGA780. The theoretically computed results are in good agreement with the experimental ones.
