双语例句
1
It can allow aparticle 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 kineticenergy 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。
2
The differential equations of motion ofaparticle constrained to moving in a constant speed are deduced from the kineticenergy 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。
3
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 kineticenergy per particle.
