“势函数”常见的英文表达是 potential function。在物理学、数学等领域中,该术语用于描述与势能相关的函数。例如:
In physics, the gravitational potential function describes the gravitational potential energy per unit mass at a given point in space.(在物理学中,引力势函数描述了空间中给定点单位质量的引力势能。)
The potential function in electrostatics helps analyze the electric field distribution.(静电学中的势函数有助于分析电场的分布。)
