The total integrated luminosity of the data samples is(5550.

897 GeV区间内67个能量点上收集了数据,我们测量了此67个能量点数据样本的积分亮度。

The integrated luminosity for the two sets of BES data,collected at s=3.

6 86GeV数据样本的积分亮度为 (6 。

Two new methods are introduced for the first time at BES to measure the integrated luminosity from events in large angle produced by QED dimuon and two gamma production processes.

介绍了利用e+ e- 对撞中双 μ产生和双γ产生两种QED过程来测量积分亮度的新思路 。
