有位法国的哲学家看到埃菲尔铁塔时说:“铁是轻的”。的确如此,倘若铁重的话,这么大的塔,也许会像古巴比伦塔一样,由于不能支持本身的重量而倒塌,巴比伦塔是古巴比伦人建筑未成的通天塔。 铁作为支持我们文明的材料进入人们的生活中,现在是铁的时代。铁在强度和性能方面,比我们所了解的任何材料都优良,覆盖地球的各种形态的建筑物中都有它的存在。可以用它来建造形态各异的空间建筑, A French philosopher saw the Eiffel Tower and said: “Iron is light.” Indeed, if it is heavy, such a large tower may, like Cuba’s Bilunta, be able to collapse due to its inability to support its own weight. The Babylon Tower is a communal tower unfinished by the Babylonians. Iron has entered people’s lives as a material that supports our civilization. It is now an iron age. Iron is superior to any material we know in terms of strength and performance, and it exists in buildings that cover all forms of Earth. It can be used to build a variety of space architectures.
