In [[mathematics]], a '''partial differential equation''' ('''PDE''') is a [[differential equation]] that contains unknown [[Multivariable calculus|multivariable functions]] and their [[partial derivative]]s. PDEs are used to formulate problems involving functions of several variables, and are either solved by hand, or used to create a [[computer model]]. A special case is [[ordinary differential equation]]s (ODEs), which deal with functions of a single variable and their derivatives.

PDEs can be used to describe a wide variety of phenomena such as sound, heat, diffusion, electrostatics, electrodynamics, fluid dynamics, elasticity, gravitation and quantum mechanics. These seemingly distinct physical phenomena can be formalised similarly in terms of PDEs. Just as ordinary differential equations often model one-dimensional dynamical systems, partial differential equations often model multidimensional systems. PDEs find their generalisation in stochastic partial differential equations.

偏微分方程可以用来描述各种各样的现象,如声音,热量,扩散,静电,电动力学,流体动力学,弹性,重力和量子力学。这些看起来截然不同的物理现象可以用类似的偏微分方程来形式化。正如常微分方程经常对一维动力系统进行建模一样,偏微分方程经常对多维系统进行建模。偏微分方程在随机偏微分方程中得到了推广。
