class="mw-disambig" title="指標">指标</a>。例如,取一3阶张量尺寸为2x5x7。这里,指标的范围从&lt;1,1,1&gt;到&lt;2,5,7&gt;。张量可以在指标为&lt;1,1,1&gt;有一个值,在指标为&lt;1,1,2&gt;有另一个值,等等一共70个值。

class="mw-redirect" title="多线性映射">多线性映射</a>来局部的逼近。这样多数物理学中的量都可以用张量表示。 </p><p>作为一个简单的例子,考虑水中的船。我们要描述它对受力的反应。力是一个向量,而船的反应是一个加速度,它也是一个向量。通常加速度不是和受力的方向相同,因为船体的特定形状。但是,这个力和加速之间的关系实际上是<a href="/wiki/%E7%BA%BF%E6%80%A7%E7%AE%97%E5%AD%90" class="mw-redirect" title="线性算子">线性</a>的。这样一个关系可以用一个(1,1)类型(也就是说,它把一个向量变成另一个向量)的张量表示。这个张量可以用<a href="/wiki/%E7%9F%A9%E9%98%B5" title="矩阵">矩阵</a>表示,当它乘以一个向量时就得到另一个作为结果。坐标系改变的时候,表示一个向量的数字会改变,同样,表示这个张量的矩阵中的数字也会改变。 </p><p>工程上,<a href="/wiki/%E5%88%9A%E4%BD%93" title="刚体">刚体</a>或<a href="/wiki/%E6%B5%81%E4%BD%93" title="流体">流体</a>内的<a href="/wiki/%E6%87%89%E5%8A%9B" title="應力">应力</a>也用一个张量表示;"张量"一词的拉丁语就表示引起张力的某种拉伸。如果材料内的一个特定的表面元素被选出来,在表面一侧的材料会对另一侧的施加一个力。通常,该力不和表面正交,但是它将线性的依赖于表面的朝向。这可以精确用(2,0)类型的张量精确的描述,或者更精确地说,是用一个类型为(2,0)的张量<i>场</i>来表示,因为张量可能在每一个不同。 </p><p>另外一些著名的几何中张量的例子有<a href="/wiki/%E4%BA%8C%E6%AC%A1%E5%9E%8B" title="二次型">二次型</a>,以及<a href="/wiki/%E6%9B%B2%E7%8E%87%E5%BC%A0%E9%87%8F" class="mw-disambig" title="曲率张量">曲率张量</a>。物理张量的例子有<a

href="/wiki/%E8%87%AA%E7%94%B1%E5%BA%A6" class="mw-disambig" title="自由度">自由度</a>来分类。标量是那些可以用一个数表示的 --- <a href="/wiki/%E9%80%9F%E7%8E%87" title="速率">速率</a>,<a href="/wiki/%E8%B4%A8%E9%87%8F" title="质量">质量</a>,<a href="/wiki/%E6%B8%A9%E5%BA%A6" title="温度">温度</a>,等等。有一些向量类型的量,例如<a href="/wiki/%E5%8A%9B" title="力">力</a>,它需要一个数字的列表来表述。最后,像二次型这样的量需要用多维数组来表示。后面这些量只能视为张量。 </p><p>实际上,张量的概念相当广泛,可以用于上面所有的例子;标量和向量是张量的特殊情况。区别标量和向量以及区别这两者和更一般的张量的特征是表示它们的数组的指标的个数。这个个数称为张量的<b>阶</b>。这样,标量是0阶张量(不需要任何指标),而向量是一阶张量。 </p><p>张量的另外一个例子是<a
