Abstract: Using two experiments, the characteristics of implicit representation of time on representation momentum were investigated. In operation 1 of the experiment one, the orientation of implicit time was examined; In operation 2, the succession of implicit time by changing the order of the motoring figure was examined; In operation 3, the continuity of implicit time was examined by dividing the temporal duration and the departure between the test figure and the memorial figure into 9 levels. In experiment two, the cognitive penetrability of the representation of time in representation momentum was investigated. The results showed that the implicit representation of time has characteristics of orientation,succession,continuity, and inpenetrability. It also implied that the representation of time on representation momentum is one kind of implicit representation of time.

Key words: implicit representation of time, exlicit representation of time, cognitive penetrability, representation momentum
