With some examples, the correlat ions between the thermal expansion coefficients of minerals and the types of cr ystal structures, the nature of chemical bonds, the valencies of ions , the interionic distances, the percentage ionic characters, the electronic conf igurations of ions and the chemical compositions are discussed and summarised . The crystal chemistry approach has been used in the calculation of the th ermal expansion coefficients for minerals with simple structures and composition s.

晶體化學方法是研究礦物熱膨脹系數(shù)的有效方法，但由于礦物的熱膨脹系數(shù)和晶體化學參數(shù)之間的定量關系尚未完全弄清五月天丁香婷深夜综合，目前僅僅能對簡單結構礦物的熱膨脹系數(shù)進行計算，結構、成分較復雜的礦物的熱膨脹系數(shù)計算尚缺乏好的晶體化學模型人人草网。
