摘　　要：本文以 P2_12_12_1空间群为例,采用结构因子代数方法推导出适用于±π/2型相角估算的1.5阶和2.5阶代数公式,并应用于两个已知晶体结构的±π/2相角计算,获得了令人满意的结果.The algebraic formulas of 1.5 and 2.5 rank which can be applied to estimating±π/2 type of phases for P2_12_12_1 space group were derived using the method of structurefactor algebra.Both types of the formulas are satisfactory for two known crystalstructures in estimating their ±π/2 type of phases.
