The energy of a particle or system of particles derived from position, or condition, rather than motion. A raised weight, coiled spring, or charged battery has potential energy.
粒子或粒子系统因其位置或状态而非运动而具有的能量。举起的重物、压紧的弹簧或充了电的电池都具有势能。
The equation for the evolution of the pulse width is obtained, which is analogues to the "energy conservation equation" for a classical particle moving in a potential well.
给出了脉宽演化的方程，它类似于在势阱中运动的经典粒子的能量守恒方程；估算了脉宽压缩对应的等离子体波振幅阈值。
The energy spectrum of a particle in one-dimensional power potential well is analyzed and the variation of the spectrum shape with the power is discussed.
分析了一维幂次势阱中粒子的能谱，讨论了能谱形状随幂次变化的规律。
