The Editor-in-Chief has retracted this article [1], because one of the Editorial Board Mem- bers pointed out that Lemma 3.5 in [1] has an uncorrectable gap which can only be true when n = 1, 2, 3, indicating that the major theorem 1.1 in [1] is only a special case of Theorem 1 in [2], and Theorem 1.2 in [1] is only a trivial result in [3]. The author refused to retract the article [1] in his first response to editors and claimed that the existing gap is unimportant. The author has not responded again by the deadline clearly informed to the author.

撤稿说明：“通过 Nehari 流形方法对某些哈密顿系统的最小周期对称解”

主编撤回了这篇文章[1]，因为其中一位编辑委员会成员指出，[1] 中的引理 3.5 有一个不可纠正的差距，只有当 n = 1, 2, 3 时才能成立，表明[1]中的大定理1.1只是[2]中定理1的特例，[1]中的定理1.2只是[3]中的一个平凡结果。作者在第一次回复编辑时拒绝撤回文章[1]，并声称现有的差距并不重要。作者在明确告知作者的截止日期前没有再次回复。
