Total Nickel Content 总镍含量
By chemically extracting nickel form the ash, they produced 100 pounds of nickel per acre of land at a total cost per pound slightly above that of current mining.
通过化学方法从灰烬中提取镍，他们每英亩土地生产了100磅镍，每磅的总成本略高于目前的采矿成本。
Total quantifies of zinc and nickel are determined with EDTA volumetry, from the total quantities minus the nickel concentration we obtain the zinc concentration.
用EDTA容量法测定锌和镍的总量，用差减法计算锌的质量浓度；
The ratio of the thermal conductivity due to phonon-phonon interactions to the total thermal conductivity is about 33.0% in solid bulk nickel.
对于块体金属镍，由于声子-声子作用引起的热导率约占其总热导率的33.0%左右。
