矿物热膨胀系数计算的修正Ruffa法及其应用

THE REVISED RUFFA METHOD OF CALCULATING THERMAL EXPANSION COEFFICIENTS OF MINERALS AND ITS APPLICATION

对矿物热膨胀系数计算的Ruffa法进行了详细的评估和修正,提出了矿物热膨胀系数计算的修正Ruffa法;用Ruffa法、修正Ruffa法对若干种结构类型的矿物的热膨胀系数进行了计算并与实验结果进行对比,结果表明修正Ruffa法比Ruffa法具有更高的精度和更广的适用范围。

An important method for mineral thermal expansion coefficient calculation proposed by A.R.Ruffa (Ruffa Method) is introduced and discussed in detail. Limitations of the method are pointed out and complemented. The so-called Revised Ruffa Method has been proposed. Thermal expansion coefficients of more than 100 minerals of different structure type are calculated by using the Ruffa Method and Revised Ruffa Method. The comparison of the calculated and experimental data shows that the Revised Ruffa Method has found wider applications and has higher accuracy than the Ruffa Method.
