Abstract As influence of beaming effect, the entry conditions of the next tube in vacuum pumping line is different, from the tube which connects with a big vessel, so the transmission probability which was worked out by the experience approximate expression will lead to more errors.
由于集束效应的影响,真空管路中后续管道与入口连接大容积的管道的入口条件不相同,因而其传输几率的计算用现有的近似计算公式将会导致较大的误差。
