在储存环中束流寿命与残气压强息息相关，而储存环真空系统的特殊结构又影响压强计算、测量的精确性，因此储存环压强的准确读取一直为人们所关注。本文主要介绍合肥光源(HLS)储存环真空系统压强分布的计算，将计算结果与实际运行数据比较，两者基本相符，因此该计算程序可用于预测、模拟环真空系统各种运行状态。

The lifetime of a beam strongly depends on the pressure of the residue gases in a storage ring.Technically speaking,however,it is rather difficult to get low base pressure and to evaluate the pressure distribution inside the storage ring because of its irregular shape and its complicated structure.Based on experimental data,we successfully developed a computer program to calculate the pressure distribution in the HLS vacuum system.The calculated results agree well with measurements.The program can also be used to predict and simulate the operation of the vacuum system of the storage ring.
