1·2 mg of copper as cupric oxide.
铜氧化物中铜质2毫克。
2·But they shrink at different rates, which makes the black cupric oxide flake off.
但是，他们在不同的收缩率，从而使黑色铜氧化物片赶走。
3·The chlorination equilibrium of cupric oxide has been investigated using the circulation method.
用循环法研究了氧化铜氯化反应平衡。
4·The cupric oxide separated from material treated by shaking table was 96.5% in purification and 97.1% in recovery rate.
在此条件下处理后的物料，通过摇床分选后得到的氧化铜纯度达96.5%，回收率达97.1%。
5·As the copper cools, it shrinks. The black cupric oxide also shrinks. But they shrink at different rates, which makes the black cupric oxide flake off.
由于铜冷却，它缩小。黑色铜氧化物也缩小。但是，他们在不同的收缩率，从而使黑色铜氧化物片赶走。
