该文通过对苯乙烯蒸汽压的计算，引出了苯乙烯蒸汽压力与温度之间的关系，从而对ＶＰＩ设备设计中苯乙烯气体的冷凝捕集、苯乙烯冷凝捕集器在真空抽气系统中的安放位置、真空抽气系统的合理选配提供了理论依据。
In this paper, the calculation of the vapor pressure of styrene leads to the relationship between the vapor pressure of styrene and the temperature, so as to condense and trap the styrene gas in the design of the VPI equipment. The styrene condensate trap in the vacuum extraction system The placement of vacuum pumping system provides a reasonable basis for the rationale.
