摘要：
In this paper we consider the gravitational energy and its flux in the Bonnor spacetime. We construct some non-local expressions from the Einstein canonical energy-momentum pseudotensor of the gravitational field which show that the gravitational energy and its flux in this spacetime are different from zero and do not vanish even outside of the material source (a stationary beam of the null dust) of this spacetime. Thus, the hypothesis which states that the energy and momentum in Bonnor's spacetime are confined to the regions of non-vanishing energy-momentum tensor of matter cannot be correct.
