摘要
探讨了硅酸盐矿物标准熵的变化规律与其结构参数之间的关系，提出了计算复杂硅酸盐矿物标准熵的新模型，并用新方法计算了６０余个硅酸盐矿物的标准熵，其结果与已有的实验数据相当一致．公式计算方便，准确性高，物理意义明确．
An approach based on the molecular structure theory was used to study the relationship between standard entropies of silicates and their structure, and an calculation method for standard entropies of complex silicate minerals was proposed. Through calculation of standard entropies of 60 homologous chemical compounds, it is showed that the results of calculation are in accordance with experiments, the standard deviation is less, and the physical meaning is clear. Through calculation and comparison, the typical features of the method can be summarised as: high accuracy, easiness of calculation, simplification of formulation and effective.
