Words whose three successive factors of the same length are all different i.e. 3-anti-power words are a natural extension of square-free words (two successive factors of the same length are different). We give a way to verify whether a uniform morphism preserves 3-anti-power words (the image of a 3-anti-power word is a 3-anti-power word). A consequence of the existence of such morphisms is the possibility of generating an infinite 3-anti-power word.

3-反幂一致态射

三个相同长度的连续因子都不同的单词，即3反幂词是无平方词的自然扩展（相同长度的两个连续因子不同）。我们给出了一种方法来验证一致态射是否保留3-反幂词（3-反幂词的图像是3-反幂词）。这种态射存在的结果是有可能生成无限的 3 反幂词。
