This discovery led Perkin to start a company using this chemical mixture to make purple dye.

这一发现促使珀金创办了一家公司，使用这种化学混合物来制造紫色染料。

And then we'll have an equation that will compare the chemical potential of the mixture under the same conditions as the chemical potential of a in the pure state.

那么我们就得到了一个式子，用它可以来比较混合态的化学势，和相同条件下，纯态时的化学势。

So our goal, then, is to have a mixture, chemical potential of the mixture on one side, and the chemical potential of the pure material on the other side.

我们的目的是，有一个混合物，混合物的化学势在这边，纯净物的化学势，在另一边。

The students use the mixture to fertilize the soil instead of buying chemical fertilizers that could harm the environment.

Mr Holmes rigged a fuse between three glass jars filled with a potent chemical mixture that would burn at such a high temperature that it could not be put out with water, he said.

The result, if all goes well, will be a mixture of hydrocarbons that can be fed into the stage of the oil-refining process just before petrol and diesel emerge from the stills, and at a price that competes with the equivalent chemical mixture produced by traditional methods.
