A survey of recent entries in the Cambridge Structural Database suggests that the percentage of structures described in space groups of inappropriately low symmetry has decreased from about 10% in the early 2000s to less than 5% today for space group Cc, but that for space group P1 it remains close to 8%.
对剑桥结构数据库中近期收录内容的一项调查表明,对于空间群Cc,描述为具有不适当低对称性空间群结构的比例已从21世纪初的约10%降至如今的不到5%,但对于空间群P1,这一比例仍接近8%。
