先看表1某些周期数列的通项公式(通项公式不一定是唯一的). 表1中这些数列虽然是最基本、最简单的,但是,由这些数列出发可以诱导出许多数列.例如数列1,1,0,0,1,1,0,0,……,乍看起来,似与数列⑤很不一样,但实际上,这个数列的各项可由数列⑤的各项加上1 Let us first look at the general formulas for certain cycles in Table 1 (the general formulae are not necessarily unique). Although these sequences in Table 1 are the most basic and simple, they can induce many series by listing them. The series 1,1,0,0,1,1,0,0,......, at first glance looks like very different from the series 5, but in fact, the items of this series can be added by the number 5 items plus 1
