When force, a vector, is combined with another vector that provides orientation, we have the physical quantity called stress, which is an example of a second order tensor.

当力（一个矢量）与另一个提供方向的矢量结合时，我们就有了称为应力的物理量，它是二阶张量的一个例子。

But, since this deduction is not a deduction in terms of money, he is involved in assuming that there can be a change in physical quantity, although there has been no physical change; i.e. he is covertly introducing changes in value.

但是，由于这种推论不是货币形式的推论，他假设物理量可能会发生变化，尽管没有发生物理变化；也就是说，他正在秘密地引入价值的变化。
