在日常生活中人们所接触的材料不外乎晶态和非晶态两类。在晶态材料中,原子的排列遵循一定规则;反之,如果原子排列处于无规则状态,就称为非晶态材料。像食盐、钻石以及我们认识的所有金属,都属晶态材料,而木材、纺织品和玻璃都属非晶态材料。 In everyday life people contact with the material nothing more than crystalline and amorphous two categories. In crystalline materials, the arrangement of atoms follows a certain rule; on the other hand, if atoms are arranged in a random state, they are called amorphous materials. Like salt, diamonds and all the metals we know are crystalline materials, and wood, textiles and glass are amorphous materials.
