金——金属之王。由于它在天然条件下以自然金状态出现,即具有金黄闪亮、色泽动人的外观和难氧化的特殊物理化学性质,因此几乎在人类社会的初期就将其用于日常生活。我国是利用黄金制品最早的国家之一。早在商代就用黄金做成贝币。时至今日,世界上用作货币的黄金量仍占金产量的半数以上。随着人类社会的发展和科学技术的进步,黄金的应用更为广泛。除作国际货币、装饰品、奖品、纪念品外;在现代工业中(计算机、通讯设备、电子、航空航天等方面)和医疗事业上黄金都排上了极为重要的用场。
Gold - the king of metal. Because it appears in a natural gold state under natural conditions, that is, it has a golden shiny, color attractive appearance and special physicochemical properties that are difficult to oxidize, it is used in daily life almost in the early days of human society. China is one of the earliest countries to use gold products. As early as the Shang Dynasty, it used gold to make shellfish. Today, the amount of gold used as a currency in the world still accounts for more than half of the gold production. With the development of human society and the progress of science and technology, the application of gold is more extensive. In addition to international currency, decorations, prizes, and souvenirs, gold is an extremely important use in modern industries (computers, communications equipment, electronics, aerospace, etc.) and medical services.
