摘　　要：From discussion of the structure of liquid water, we deduce that water under ambient condition is mainly composed of ice Ih-like molecular dusters and clathrate-like molecular clusters. The water molecular dusters remain in a state of chemical equilibrium （reversible clustering reactions）. This structural model can be demonstrated by quantitative study on anomalous density with increasing temperature at ambient pressure.From discussion of the structure of liquid water, we deduce that water under ambient condition is mainly composed of ice Ih-like molecular dusters and clathrate-like molecular clusters.
