不同商品在价值上的相等，通过交换来实现（体现）。

欢迎直译。

通过一个的交换行为，我们实现（体现）了不同商品在价值上的相等关系。

“By an exchange we equate as values our different products.”

通过交换,我们的不同产品的不同性消失,在价值上是无差异的.即个别劳动的差异性通过交换实现价值(无差异的人类一般劳动)

“By an exchange we equate as values our different products.”

看了上面这些翻译,我想他们的资产阶级思维惯性还在,既市场思维模式.

应该如下翻译:

通过交换,我们的不同产品的不同性消失,在价值上是无差异的.即个别劳动的差异性通过交换实现价值(无差异的人类一般劳动)

"Whenever, by an exchange, we equate as values our different products, by that very act, we also equate, as human labour, the different kind of labour expended upon them. We are not aware of this, nevertheless we do it."

Karl Marx

可以再看如下的解释:

A commodity is, in the first place, a thing that satisfies a human want; in the second place, it is a thing that can be exchanged for another thing. The utility of a thing makes is a use-value. Exchange-value (or, simply, value), is first of all the ratio, the proportion, in which a certain number of use-values of one kind can be exchanged for a certain number of use-values of another kind.

Daily experience shows us that millions upon millions of such exchanges are constantly equating with one another in every kind of use-value, even the most diverse and incomparable. Now, what is there in common between these various things which are constantly equated with one another in a definite system of social relations?

Their common feature is that they are products of labour. In exchanging products, people equate with one another the most diverse kinds of labour. The production of commodities is a system of social relations in which individual producers create diverse products (the social division of labour), and in which all these products are equated with one another in the process of exchange.

Consequently, what is common to all commodities is not the concrete labour of a definite branch of production, not labour of one particular kind, but abstract human labour – human labour in general. All the labour power of a given society, as represented in the sum total of the values of all commodities, is one and the same human labour power. Thousands upon thousands upon millions of exchanges prove this.

As a result, each particular commodity represents only a certain share of the socially necessary labour time. The magnitude of value is determined by the amount of socially necessary labour, or by the labour time that is socially necessary for the production of a given commodity, of a given use-value.

《资本论》中文本的原话是：人们“在交换中使他们的各种产品作为价值彼此相等，也就使他们的各种劳动作为人类劳动彼此相等。他们没有意识到这一点，但是他们这样做了。”这是准确地表达了马克思的原意的：价值是被物质外壳掩盖着的社会劳动关系。
