一青铜是人类最早冶炼和使用的金属。由于青铜的主要成分或以自然状态出现,由于青铜本身作为一种合金所具有的一些物理性能,诸如熔点低、硬度高、易于铸造成型等,使得其排他地成为人类使用金属的首选和发端。于是青铜器便成为人类发明陶器之后的又一项重大发明,一次以火为能源的又一次科技革命。青铜器的出现对于提高社会生产力,促进人类社会的全面进化和加速度发展,起了划时代的历史作用。因此成为继石器时代,这一人类社会史上最漫长、最黑暗的历史时期之后一个新的时代的主要标志,这就是考古学所谓的“青铜时代”。 A bronze is the earliest metal smelt and used by mankind. Due to the main component of bronze or occurring in a natural state, bronze itself is an exclusive choice for metal for human use because of its physical properties as an alloy, such as low melting point, high hardness and easy casting and casting. Thus, bronze ware became another major invention after the invention of pottery by human beings, and another scientific and technological revolution with fire as its source of energy. The emergence of bronze played an epoch-making historical role in raising social productivity and promoting the all-round evolution and acceleration of human society. Therefore, it became the major symbol of a new era after the stone age, the longest and the darkest historical period in the history of human society. This is what archeology calls the “Bronze Age.”
