| 摘 要： | 文1]定理2给出了形如w xw的间隙为x（｜x｜≤4）的双边无限C∞字所确定的无限C∞字w恰有12个.文章在此研究定理2的逆问题,并完全确定了形如wxw的双边无限C∞字的间隙x的取值,其中w是由定理2确定的12个无限C∞字.

| Abstract: | In 1] ,Theorem 2 has established that there are exactly twelve infinite C∞-words w determined by bi-infinite C∞-words as the form xw with the gap ｜x｜≤4. This paper studies the inverse problem in Theorem 2 and gives out the gaps x of bi-infinite C∞-words as the form xw,where w takes the twelve infinite C∞-words determined by Theorem 2 in 2]. |
