钢铁在工业进展中似乎至今还保持着牠的相当地位,只是「钢铁世界」或「钢铁时代』」一类名词,似乎到最近已不很热闹。代■而兴的,有什么「化学时代」、「百赖斯替时代」、「原子时代」和「轻金属时代」等;看来钢铁的那把「时代」宝座,迟早将要拱手让人,这似乎也已经成为定论。究竟那一位将继钢铁而接受这「时代」的宝座呢?就基本建造材料而言,将来能代替钢铁的,一般人认为不是别的,而是轻金属中的镁,所以下一个时代可直捷的称之为「镁时代」。这是因为镁具有轻而坚韧的性质,适用以制造各种机件;而且镁含于海水 It seems that steel still holds its place in the industrial development so far. It is only a category of terms such as “the steel world” or “the steel age” that seems to have not been very lively recently. What is the “Chemical Age,” “the Age of Bryce,” “the Atomic Age,” and the “Light Metal Age,” etc., which appear on behalf of others; it seems that sooner or later, the “era” of steel is to be overwhelmed Seems to have become a conclusion. After all, who will inherit the throne of steel and accept this “era?” In terms of basic construction materials, in the future to replace steel, most people think it is nothing but magnesium in light metals, so the next era can be direct Called “the age of magnesium.” This is because magnesium has a light and tough nature and is suitable for use in the manufacture of various parts; and magnesium is contained in seawater
