摘要
以Einstein场方程和Lorentz LeviCivita守恒律为基础 ,对引力波是否传播能量、动量问题进行了新的探讨 .对物质体系在发射和接收引力波时的能量转换作了新解释 .
Based on the Einstein′s field equations and the Lorentz Levi Civita′s conservation laws, the properties of the gravitational wave are reexamined. The theoretical foundations of the viewpoint whether the gravitational waves carry the energy momentum or only transmit informations of the metric variations are expounded. A new interpretation for the energy exchanges of the matter system is given when there exists the gravitational wave. One observation method which can be used to test whether the gravitational waves carry energy or not via the background gravitational waves is proposed and discussed.
