We study the genuine tripartite nonlocality of some qubit states in a triple JCM. In this model, each atom state (A, B or C) was initially prepared with an independent cavity (a, b or c). By using two kinds of GHZ-like states as the atomic initial states, we investigate the genuine tripartite nonlocality as the time evolutions for the non-interaction three-qubit subsystems. We also study the genuine tripartite nonlocality of the subsystems by using the Svetlichny inequality. For the subsystems of three atoms ABC and three cavity modes abc, we show that they are genuinely nonlocal at certain period intervals of time. The states of all the other inequivalent subsystems satisfy the Svetlichny inequality for two types of GHZ-like states.
我们研究了三模Jaynes-Cummings模型中一些量子比特态的真正三方非定域性。在该模型中，每个原子态（A、B或C）最初是在独立的腔（a、b或c）中制备的。通过使用两种类GHZ态作为原子初始态，我们研究了非相互作用三量子比特子系统随时间演化的真正三方非定域性。我们还使用Svetlichny不等式研究了子系统的真正三方非定域性。对于三个原子ABC和三个腔模abc的子系统，我们表明它们在特定的时间周期间隔内是真正非定域的。对于两种类GHZ态，所有其他不等价子系统的态都满足Svetlichny不等式。
