说明：  ⑴ 温度设定范围为40～90℃。 ⑵ 环境温度降低时（例如用电风扇降温）温度控制的静态误差≤1℃。 ⑶采用适当的控制方法，当设定温度突变（由40℃提高到60℃）时，减小系统的调节时间和超调量。 ⑷用十进制数码管显示水的实际温度。 ⑸ 在设定温度发生突变（由40℃提高到60℃）时，自动打印水温随时间变化的曲线。
(1 the temperature setting for 40 ~ 90 ° c range. 2 environment temperature decreases with electric (for example) temperature control of static error than 1 ° c. (3) using appropriate control method, when the temperature of 40 degrees Celsius mutations (to 60 ° c), reduce system to adjust the time and overshoot. 4 decimal digital display with the actual temperature of the water pipe. [5] in setting temperature mutations (by 40 ° c to 60 ° c), automatic printing temperature changes with time curves.)
