驻波能量及能流密度局部振荡理论探析
Study on theory of wave energy and energy density of local oscillation
摘要
Abstract
This paper focused on the standing wave formed by superposition of harmonic shear waves which propagated along the rod ( the cross sectional area of S, the mass density of ρ) in opposite directions .It demonstrated that the standing wave energy distribution curve and energy flow density curve were both similar as standing wave curve .If the matter element be-tween adjacent wave loop and wave nodes was called a segment , the conversion and transfer of energy only occurred in the same segment , and the average energy flow density was equal to zero within half a cycle .The results showed that there was no single direction energy flow in standing wave .关键词
