摘　　要：对等度连续半流的性质进行了研究。证明了等度连续半流实际上是等度连续流,半流的等度连续性与几乎周期性等价;等度连续半流轨道的闭包是极小集,且存在一个连续映射。Some properities of equicontinuous semi-flow have been investigated in this paper.It is shown that the equicontinuous semi-flow is actually equicontinuous flow and equicontinuity of semi-flow is equivalent to almost periodicity.Moreover,the closure of orbit of the equicontinuous semi-flow is minimal and there exists a continuous map.

关 键 词：半流 等度连续性 几乎周期性 极小集
