摘要
本文提出了自然金—银类质同象系列矿物晶胞参数与金、银原子数百分比成二次函数关系,并推导出了表示二者之间函数关系的方程式。利用该方程式,可以用金原子数百分比计算出晶胞参数,反之亦然。并首次将其应用在自然金—银类质同象系列矿物的研究中。
The article suggests that in the isomorphous series of gold-silver, at both mineral cell parameters and the atomic number of Au or Ag, the twice functional relationship appears. And it has inferred the equation expressing the functional relationship between the both. The equation is as follows:
a0 = 0.0218667X2-0.0294667x + 4.0862 (unit: 10-10 ×m )
In the equation ao is the edge length of a unit cell; X is the atomic number percentage of Au.Using the quadratic equation, the cell parameter can be calculated by the atomic number percentage of Au or Ag and vice versa.
