Next, we use a new hardening process developed by our metallurgists to strengthen a metal that is naturally very soft.

随后，再采用我们的大师制定的全新强化工序，让这一本来十分柔软的属变得更为坚固。

The core coal metallurgical business, that continues to be weak.

核心的煤炭业务依然疲软。

Once the Industrial Revolution got underway, improved metallurgy and mass production techniques resulted in the dip pen.

工业革命开始后，改进的技术和大规模生产技术导致了蘸水笔的出现。

The modification Doctors Ding and Kildall propose cuts coke out of the loop by pumping CO directly into the blast furnace.

和基尔达尔提出的改良方案是直将一氧化碳泵入高炉，从而省去了炭的使用。

The point of replacing coke with hydrogen would have been to reduce the ore in a way that created water rather than CO2, thus eliminating climate-warming emissions.

用氢气替代炭的目的在于以产生水而非二氧化碳的方式来还原铁矿石，从而消除导致气候变暖的排放。

That metal instead requires a process called hydrometallurgy in which old batteries are crushed and the resulting " black mass" is treated with harsh chemicals known as lixiviants.

相反，这种属需要一种称为湿法的工艺，其中将旧电池粉碎，然后用称为浸出剂的刺激性化学物质处理所产生的“黑色物质”。

Assumed metallurgical recoveries and payabilities for all metals and discussion of the basis on which the assumed recoveries and payabilities are derived (metallurgical test work, detailed mineralogy, similar deposits, etc.).

• 假设所有属的回收率和可付款率，并讨论得出假定回收率和可付款率的基础（测试工作、详细的矿物学、类似的矿床等）。

Chromium's effect on iron and steel had been observed for decades, but it wasn't put to practical use until 1913, when a metallurgist named Harry Brearley was looking for ways to prevent corrosion in gun barrels.

铬对铁和钢的影响已经被观察了几十年，但直到 1913 年，一位名叫哈里·布里尔利的学家在寻找防止枪管腐蚀的方法时，才将其付诸实践。

Two of the three operating plants are based on designs from China Envy Engineering Corporation, a subsidiary of the China Metallurgical Group Corporation that operates as an HPAL plant in Papua New Guinea.

三家运营工厂中的两家基于中国羡慕工程公司的设计，该公司是中国集团公司的子公司， 作为巴布亚新几内亚的HPAL工厂运营。

However, the researchers estimate that, besides the green benefits accruing, the initial investment would be repaid in 22 months by the elimination of expensive metallurgical coke from the process, and from selling any oxygen that was surplus to requirements.

然而，研究人员估计，除了产生的绿色效益外，初始投资将在 22 个月内通过从工艺中消除昂贵的炭以及出售任何多余的氧气来收回。

The metallurgical skills, inks, and presses of 1700 B.C.Crete were more primitive than those of A.D.1455 Germany, so the disk had to be punched by hand rather than by cast movable type locked into a metal frame, inked, and pressed.

公元前 1700 年克里特岛的技术、墨水和印刷机比公元 1455 年德国的技术、墨水和印刷机更为原始，因此磁盘必须用手冲压，而不是通过锁定在属框架中的铸造活字印刷、上墨和压制。
