摘要 通过选择适当的比特串101、1011、1101、11100、111010和111011来分析其出现次数的奇偶性,证明了广义自缩序列b(ak+1+ak+2)的最小周期在所有1024种情形下全部达到最大,即2n-1。并且得到若干组比特串,在每组比特串情形下,证明了广义自缩序列b(ak+1+ak+2)的最小周期都达到最大。 By analysing the appearing times of some relevant string in generalized self-shrinking sequence b (ak+1+ak+2), it is proved that the least period reaches the maximum, namely 2n-1. And certain group of bit string are obtained, in any group case, it is also proved that their least periods reach the maximum.
