| 摘 要： | 对CF－200型饱和蒸汽压实验装置进行了改进，变过去用电子继电器来控制加热管的通断为用运算放大器来控制，过去从水银温度计上读数为数显读数，读数更加精确；并且提高了学生在做实验时的安全性。

| Abstract: | The saturated vapour pressure experimental apparatus of CF?200 type has been improved.The heater is controlled by silicon controlled rectifier instead of by electromagnetic relay,and the data of experimental temperture have been obtained by the digital display,which is more accurate to read and it is safer for the students to determine experimental data. |
