摘要
用失重法研究了金属铅在真空中蒸发的基本规律．得到了临界压力与温度的关系式，铅蒸发速率温度和压力的关系式。
The basic evaporation laws of lead in vacuum are studied.It is confirmed that the critical vapor pressure of lead certaily exists in the process of evaporation.The relationship between the lead critical vapor pressure and temperature are obtained by experiment and that between the Lead evaporation rate and temperature are also obtained by experiment.
