It is shown that, in such a DWP, the average number of condensed atoms in the two traps is still same in presence of tunneling effect, this ensures the visibility of interference fringes of atoms.

结果表明，在这样的双阱势中，尽管隧道效应存在，凝聚在两个阱中的平均原子数依然相等，这保证了原子干涉的可见度。

With increasing beam separation, the number of interference fringes increases and the fringe separation and visibility decrease.

随着光束间距的增大，干涉条纹间距减小，条纹数目增多，条纹可见度减小；

With increasing beam waists, the number of interference fringes increase, but the fringes separation and visibility change little.

光束束腰半径增大时，干涉条纹数目增多，条纹间距变化很小，对条纹可见度影响不大。
