摘要：

It is shown that a structural glass obeying rather general assumptions will have regions that flow in the presence of gravity. The fraction of the regions which move depends exponentially on the strength of the gravitational field. This result demonstrates the existence of marginally stable degrees of freedom and implies that the many-valley picture of the configuration energy of the glass phase may have to be modified.
