And I don't recall that changing in value over the last year.

我不记得去年价值的变化。

These changes in value usually don't register in our brain quite as strongly as they should.

这些价值的变化通常不会像应有的那样强烈地记录在我们的大脑中。

If, however, one of the alternative standards is expected to change in value in terms of the other, the marginal efficiencies of capital-assets will be changed by the same percentage, according to which standard they are measured in.

然而，如果其中一个替代标准预计会根据另一个标准发生价值变化，则资本资产的边际效率将根据衡量标准的相同百分比发生变化。

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。
