查询词典 pressure element

Coordinating among these parameters is crucial but the basic element of the evaluation is still the operation weight of compactors, which represents an equivalent pressure of the vibratory drum. For the two kinds of single drum vibratory compactors, fully hydraulic drive and mechanical drive, compacting capability of the former is certainly higher than that of the later.
