In order for energy to be conserved, the final total kinetic energy must be greater than the initial by this amount.
要符合能量守恒原理，末总动能必须比初动能大这么多。
Many of these appear to be fairly uniform, so by the virial theorem the total kinetic energy should be half the total gravitational binding energy of the galaxies.
多数这些好象是很统一，因此靠维里法则总动能应该是星系总引力聚合能的一半。
The total kinetic energy of a Body or system is equal to the sum of the kinetic energies resulting from each type of motion. The kinetic energy of an object depends on its mass and velocity.
物体或物体系的总动能等于每种运动方式的动能之和，取决于质量和速度。
So what, now, is then the total -- energy of the system-- that is, the sum of the kinetic energy plus the potential energy?
所以现在系统内,总能量是多少-,是动能和,势能之和吗？
So the kinetic energy has increased; the potential energy is the same, so the total energy is up.
所以动能增加，势能不变，所以总能量增加。
A collision between two particles in which part of their kinetic energy is transformed to another form of energy. The total amount of energy remains the same.
两个物体间的互相碰撞，在这个碰撞过程中，它们的一部分动能转化为其它能量形式。能量的总和不变。
The sub-grid scale turbulent energy imposed by a box filter was found to be only a small portion of the total turbulent kinetic energy, which validates the numerical method.
网格滤波截断的亚格子湍能远小于流场总能量，验证了大涡模拟方法的有效性。
To understand the micro-mechanism of the negative heat capacities, the curves of the temperature, the potential energy and the kinetic energy varying with the total energy are analyzed.
