日常摄入的水、食物和各类能量与输出的污水、固体废物、空气污染物、能源和经过某种转化的物质相匹配。
A daily input of water, food, and energy of various kinds is matched by an output of sewage, solid waste, air pollutants, energy, and materials that have been transformed in some way.
在天体物理学中，引力作用量描述了在被物质和能量弯曲的时空中如何形成引力的机理。
In astrophysics, a gravitational action is the mechanism that describes how gravity can emerge from space-time being curved by matter and energy.
