【Abstract】 Using the classical quantization way in a two dimensional integrable system and quantized energies periodic orbits correspondence relationship, the long range correlation among the quantum lavels has been discussed in detail. Making use of Berry Tabor trace formula, the quantization conditions of the action of the periodic orbits in two dimensional integrable systems have been obtained. Furthermore, considering the periodicity conditions for the periodic orbits on reasonable torus, the correspondence relations between quantum levels and classical periodic orbits in the two dimensional uncoupled oscillators have been established. It is also shown that there exist the long range correlations among these quantum levels which correspond to the group of the classical periodic orbits with same topology M (M 1,M 2) . To concert state the new points, an example has been given.
