测定液体饱和蒸气压的方法有静态法、动态法和饱和气体法。目前，国内大中专院校物理化学实验教材中多数采用静态法，虽然有些物理化学实验书［１，２］中，涉及动态法测定纯液体饱和蒸气压，但所用仪器和装置复杂，有的玻璃接头难以买到。我们设计了如下用动态法测液体蒸... Determination of liquid saturated vapor pressure methods are static method, dynamic method and saturated gas method. At present, most of the physical chemistry experiment textbooks at colleges and universities use the static method. Although some physical chemistry experiment books [1, 2] involve the dynamic method to measure the saturated vapor pressure of pure liquid, the instruments and devices used are complex and some Glass fittings difficult to buy. We designed the following dynamic method to measure liquid steamed ...
