摘要：

Dust molecules are observed in a dusty plasma experiment.By using measurements with high spatial resolution,the formation and dissociation of the dust molecules are studied.The ion cloud in the wake of an upper dust grain attracts the lower dust grain nearby.When the interparticle distance between the upper dust grain and the lower one is less than a critical value,the two dust grains would form a dust molecule.The upper dust grain always leads the lower one as they travel.When the interparticle distance between them is larger than the critical value,the dust molecule would dissociate.
