查询词典 silicon iron

"Stems shall be of dezincification-resistant silicon bronze aSTM B 371 or low-zinc alloy B 99, non-asbestos packing and malleable or ductile iron handwheel."

阀杆材质是符合美国材料试验协会aSTM B371标准抗失锌现象的硅青铜，或B99低锌合金，不含石棉的填料，和可锻或球墨铸铁手轮。

Chromium ore samples were fused by alkali and then leached out by hydrochloric acid. After the analytical lines of the elements were selected, the conditions of sample uptake, carrier gas flow, cooling gas flow and RF power were optimized with the system of SeaSpray nebulizer and cyclone spray chamber, based on the principle of best signal stability. The determination of chromium, aluminum, iron, magnesium and silicon in chromium ores was fulfilled.

铬矿石样品经碱熔融和盐酸浸取后，选用SeaSpray雾化器和旋流雾室，选定了待测元素的分析线，以信号的稳定性为原则，优化了样品提升量、载气流量、冷却气流量和入射功率，实现了电感耦合等离子体原子发射光谱法对铬矿石中铬、铝、铁、镁和硅等主量成分的测定。

And the thin degree of mineral is very thin. If want to achieve the rich purpose to collect the iron through rub the tailing again to separate the silicon and irons from the ore, it is very difficulty and the cost is too expensive.

由于浮选后的精矿品位不高，尾矿产生量大，其铁品位在43%左右，且原矿磨矿细度已经很细，如果想通过尾矿再磨，分离矿石中的硅和铁，达到富集铁的目的，难度很大，且成本不合算。

There are four parts presented in this paper. In the first part, the B.F ironmaking process, B.F Expert System and the methods to predict the silicon content in molten iron are introduced. In the second part, the control parameters and state parameters of B.F ironmaking process are analyzed. In the third part, the Statistical Learning Theory and Support Vector Machine are introduced.

论文主要包括以下四个方面的内容：高炉炼铁、高炉专家系统和炉温预测的概述；高炉冶炼过程状态参数和控制参数的分析；统计学习理论和支持向量机方法；基于支持向量机的铁水硅含量数值预报模型和铁水硅含量多类别分类模型。

The split between the two groups can hardly be papered over.

这两个团体间的分歧难以掩饰。

This approach not only encourages a greater number of responses, but minimizes the likelihood of stale groupthink.

这种做法不仅鼓励了更多的反应，而且减少跟风的可能性。
