标量(scalar),亦称“无向量”。有些物理量,只具有数值大小,而没有方向,部分有正负之分。物理学中,标量(或作纯量)指在坐标变换下保持不变的物理量。用通俗的说法,标量是只有大小,没有方向的量。

equilibrium flow is also studied. Finally, we establish a multicriteria supply chain network model, introduce the definition of scalarization solution and (weak) equilibrium solution.
最后,本文建立了多指标供应链网络模型,定义了标量化解和(弱)均衡解,并研究了标量化解、弱均衡解、均衡解之间的关系。

这些模型都有一个基础概念—守恒标量,在湍流扩散燃烧中就是混合分数,当作主要参数来描述湍流扩散燃烧中反应物的混合状态。

坐标轴包括广义同系温度,标量化动能以及净膜厚度。
The axes are comprised of a generalized homologous temperature, the normalized kinetic energy flux, and the net film thickness.
标量、数组和哈希散列。
This formula doesn't tell you which way it's pointing, because it's a scaler; it's not a vector equation.
这个式子没有说明方向,因为这是一个标量而非矢量方程
That's the very important difference.
这是矢量和标量很重要的区别
