Taken together, these results argue that life formed in places with a lot of evaporation going on (suggesting heat) and a significant amount of copper present.

总之，这样的结果说明生命形成于存在大量蒸发(也就是说热量)和铜的地方。

Copper atoms are replaced by zinc atoms as the amount of zinc is increased.

随着锌量的增加，铜原子逐步为锌原子所替代。

New copper-extracting technologies can use up to 40 percent less electricity than the older method to process the same amount of raw ore, especially when the proportion of copper in the ore is high.

在处理同等数量矿石原料的情况下，尤其是当铜在矿石中的含量很高时，新的采铜工艺可比旧式工艺少用40%的电力。

Costs for coal are highly dependent on the cost of gasoline, and the costs for wind are highly dependent on material costs like steel and concrete as wind requires about 10 times the amount of steel, concrete and copper per kWhr than any other energy source.
