标量场

标量场Scalar Field)是数学和物理学中场的一种。假如一个空间中的每一点的属性都可以以一个标量来代表的话,那幺这个场就是一个标量场。纯量场通常用不同颜色表示大小,有时候会画出等势线。

常见的标量场有温度、气压及湿度场。势场(例如电势和重力势)也是纯量场。

Scalar field 标量场

(重定向自Scalar wave)
A scalar field such as temperature or pressure, where intensity of the field is represented by different hues of color.
Un champ sur ℝ2 de la forme z = x2 – y2.

In mathematics and physics, a scalar field associates a scalar value to every point in a space. The scalar may either be a mathematical number or a physical quantity. Scalar fields are required to be coordinate-independent, meaning that any two observers using the same units will agree on the value of the scalar field at the same absolute point in space (or spacetime) regardless of their respective points of origin. Examples used in physics include the temperature distribution throughout space, the pressure distribution in a fluid, and spin-zero quantum fields, such as the Higgs field. These fields are the subject of scalar field theory.
