The energyof a particle or system of particles derived from position, or condition, rather than motion. A raised weight, coiled spring, or charged battery has potentialenergy.
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.
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.
