The system can draw not only the ideal shape of crystal, but also the practical shape of crystal, quasi-crystal, and operate the figure with...
该系统不仅可绘制晶体理想形态，也可绘出实际形态、准晶态，并对绘出的晶体图进行几何变换和投影变换。

According to the theory and practice of crystal growth from solution, we consider that there is a quasi stable region in "V" area of diamond crystallization.
本文根据溶液晶体生长理论与实践，认定在金刚石结晶V形区域内存在着晶体生长准稳定区。
