allotropy的意思是同质多象。
以下是一篇关于allotropy的英文范文：
Allotropy is a phenomenon in which a mineral undergoes a transformation into another mineral without any change in chemical composition. This process occurs through a series of intermediate phases that are characterized by a change in crystal structure and/or lattice constants. Allotropy is common in minerals that contain certain elements, such as silicon and oxygen, which can adopt different crystal structures under different conditions of pressure and temperature.
In some cases, the transformation between minerals can be abrupt, resulting in the formation of new minerals that are distinct from the parent mineral. This phenomenon is known as a new mineral or secondary mineral. Secondary minerals often form as a result of weathering processes, such as the breakdown of rock fragments or the dissolution of minerals in solution.
Allotropy plays an important role in the study of mineralogy and geology, as it provides a means of understanding the origin and evolution of rocks and mineral deposits. Understanding allotropy can also help geologists identify and classify minerals more accurately, which is crucial for mining and resource exploration activities.
allotropy的意思是同质多象。
同质多象（allotropy）是指矿物在相同压力和温度下，由于成分上的微小差异，结晶构造发生质的变化，形成新的同成分的矿物。这种变化过程称为同质多象变体。
