For example: inductive research method, comparison proving method, internal analysis method, comparison method in systemnumber, and perspective separating method.
如:归纳研究法,比勘互证法,内部分析法,系统数量比较法,透视分离法。

In our case, the two modes differ in the internal quantum number, and are a clearly distinguishable subsystem. We can thus regard the two coupled BECs as a bipartite system of the modes.
