1·Meanwhile, the crushing effect and saving energy of the equipment working in process of grinding ironstone are researched, all these lay a foundation for the further study of the technology.
同时，对高压辊磨机粉碎铁矿石的粉碎效果和工艺节能性也进行了试验研究，为该技术的进一步研究奠定了基础。
2·From 1885 the local ironstone and coal supplies were largely exhausted, with coal being sourced further south, and iron ore being imported from Spain, and from 1900 from Sweden.
从1885年当地铁矿石和煤炭供应基本上耗尽，煤源正在进一步南部，铁矿石进口来自西班牙，并从1900年由瑞典。
3·With the practical situation of ironstone resource utilization in CISC, linear programming is adopted for the optimization model.
通过比较，并考虑到重钢利用两种铁矿石资源的实际情况，决定采用线性规划方法来进行建模。
4·Ironstone is primary original material of metallurgy enterprise.
铁矿石是冶金企业生产的主要原材料。
