conservation of energy

基本解释

This principle, called conservation of energy, is one of our most cherished laws of physics.
这一原理，也即能量守恒，是物理学中最宝贵的定律之一。
As the tsunami spreads out [to] more and more area, the conservation of energy means that it is spread out over more volume.
随着海啸扩散的面积越来越广，能量守恒意味着它推动的海水量也越来越多。
This posed a conundrum for researchers working with the laser: How were they to apply the laws of conservation of charge and conservation of energy with two forms of energy output?
这就为研究激光的工作人员出了一个难题：如果能量输出有两种形式，他们怎样运用电荷守恒和能量守恒定律呢？

Each year the Washington-based League of Conservation Voters releases a scorecard that rates the performance of members of Congress on environment and energy issues.
It talks about the conservation of energy.
它讲的是能量的守恒。
