It can allow a particle to pass through a physical barrier that should be impenetrable, or can allow an electron to escape from the pull of the nucleus without having the kinetic energy to do so.
它能让粒子通过不可逾越的物理障碍，或让电子不用动能就脱离原子核的吸引力。
The differential equations of motion of a particle constrained to moving in a constant speed are deduced from the kinetic energy theorem.
对于受速率为常数约束的运动质点，可以应用动能定理建立其运动微分方程。
There must exist an average speed of molecules, just as in a large human community there exists an average age, or an average wealth. There will therefore be an average kinetic energy per particle.
在这样的气体中的分子必定有一个平均速度，正如在人类社会中有平均年龄和平均收入一样，因此也必定有粒子的平均动能。
