铁是怎样发現的? 人类最早发現的铁也許不是铁矿熔炼的产物,而有可能是天空中落下的隕石。隕石是含铁很高的金屬混合物,由于它含有鎳、鉻等金屬而具有抗腐蝕的性能,被长期保存下来。現在从埃及金字塔里,就发現了隕石的制品。隕石的发現究竟是一种罕見的偶然事件,不可能对社会生产产生什么重大的作用。而且限于当时人类知識水平,也不可能与铁矿的熔炼联系起来。因此,人类认識铁、掌握铁矿的熔炼,必然是从人們的日常生活和实际生产中产生的。并且遵循着从低級到高級、从簡单到复杂、从技艺而成为独立的科学……,这一顛扑不破的自然发展規律。
How was iron discovered? The earliest iron found by humans may not be the product of iron ore smelting, but it may be the meteorite that fell in the sky. Vermiculite is a metal mixture with high iron content. Because it contains nickel, chromium, and other metals and has corrosion resistance, it is preserved for a long time. Now from the pyramids of Egypt, we discovered the products of meteorite. The discovery of Meteorite is a rare accidental event that cannot have any significant effect on social production. Moreover, it was not possible to associate with the smelting of iron ore due to the level of human knowledge at that time. Therefore, human understanding of iron and mastering the smelting of iron ore must be derived from people’s daily lives and actual production. And it follows from the low-level to the high-level, from simple to complex, from the craft to become an independent science ... ..., this irrevocable natural law of development.
