【摘要】 本文通过热力学的克拉布朗方程导出几种矿物相对膨胀率,并通过弹性力学的物理方程给出在应力作用下矿物近似的体应变。对北京市密云沙厂地区变质矿物形变的比较,提出同一环境下矿物变形相对强弱划分的方法。更多还原

【Abstract】 in this study the relative expansibility of some minerals was derived from clausius-Brown equation of thermodynamics and approximate volume-strain by the action of stress was derived from elasticity physical equation. The deformation of some metamorphic minerals in Miyun area,Beijing,China was compared. Then a method for division of deformation intensity under same environment is proposed in this paper.更多还原
