对A~ⅡB~Ⅵ型化合物热液再结晶作用及其结晶形态的研究,从解释热液硫化物矿床成矿作用的规律性角度出发,应予以高度的重视。 另一方面,具有闪锌矿结构的A~ⅡB~Ⅵ型化合物的晶体,可以作为一种光学均质材料。因为该种晶体在宽的光谱波段内是透明的,因而有可能横向调制光束。这种化合物的天然完整晶体极为稀少。用高温方 The research on hydrothermal recrystallization and crystal morphology of A ~ ⅡB ~ Ⅵ compounds should attach great importance to explain the regularity of mineralization of hydrothermal sulfide deposits. On the other hand, crystals of A ~ IIB ~ VI compounds with sphalerite structure can be used as an optically homogeneous material. Because this type of crystal is transparent over a broad spectral band, it is possible to modulate the beam laterally. Naturally intact crystals of this compound are extremely rare.
