摘要
一般来说,图2jC4k+2(j,k为自然数)的优美性是尚未解决的问题,当j=1时,图2C4k+2的优美已有了肯定的结果,本文将给出2C4k+2的另一种优美标号,事实证明后者更简单易行.
Generally speaking, The problem about the politeness of graph 2jC4k ＋ 2（j. k are natural numbers） is not resolved. When j = 1, the politeness of graph has been obtained. In the note, Another easier polite grade is obtained.
