摘要：

We show the relation between Traschen's integral equations and energy, and the 'position of the centre of mass' of the matter perturbations in a Robertson-Walker spacetime. When perturbations are 'localized' we get a set of integral constraints that includes hers. We illustrate them in a simple example.
