The determinative method for low vapor pressure and their appliable scope are emphatically introduced. 重点介绍了低蒸气压的测定方法,列出了各测定方法的适用范围。
The change patterns of vapor pressure and solubility with temperature in the case of substance being highly dispersed are also discussed. 同时讨论了物质在分散度很大的情况下其蒸气压和溶解度随温度变化的规律。
Use pneumatic tension ,fast cutting ,reasonable structure, and easy to operate. 采用气压张力,分切利速,结构合理,操作简单。
Once the cold water enters the flack, the vapor pressure falls quickly. 一旦冷水进入长颈瓶,水气压就迅速下降。
