摘　　要：1 Introduction Throughout this note k denotes a fixed integer and k】1. Let x={x(n)}_n=0, ±, ±2,… be a real sequence. For each integer n, we denote by x(n) the median value of the following 2k+1 numbers: x(n-k), x(n-k+1), …, x(n),…, x(n+k-1), x(n+k). By this permuting operation, the sequence x={x(n)} is transformed<正> 1 Introduction Throughout this note k denotes a fixed integer and k>1. Let x={x(n)}_n=0, ±, ±2,… be a real sequence.
