应力化学是研究应力的性质、作用方式和规模、组合和序列,它们的发生、发展、演化所成生的化学作用和过程,以及物理—化学动态机制。当应力作用于地质体时,接受能量和释放能量的作用方式之一就是应力化学作用。应力化学作用主要受应力性质、应力配置和应力序列的影响,以剪应力化学作用最为重要。应力作用可产生化学作用,改善化学反应所需条件,因而促进和加速了化学作用。 Stress chemistry is the study of the nature of stress, mode and size of action, composition and sequence, their occurrence, development, chemical evolution and evolution process, as well as the physical - chemical dynamic mechanism. When stress acts on a geologic body, one of the modes of action that takes energy and releases energy is stress chemistry. Stress chemistry is mainly affected by stress properties, stress distribution and stress sequence, and the most important is chemical action of shear stress. Stress can produce chemical effects, improve the conditions required for chemical reactions, thus accelerating and accelerating the chemical effects.
