Direct phasing techniques using cosine estimates for three-phase and four-phase structure invariants in space group P1 are applied to zonal hk0 electron diffraction intensity data from an orthorhombic paraffin and a cephalin. Ab initio use of these kinematical phases is shown to derive the correct structures of the methylene subcell packings for these compounds in agreement with earlier determinations from Patterson maps.
利用空间群P1中三相和四相结构不变量的余弦估计的直接定相技术，被应用于来自正交石蜡和脑磷脂的带状hk0电子衍射强度数据。结果表明，这些运动学相位的从头计算能够得出这些化合物亚甲基子晶胞堆积的正确结构，这与早期从帕特森图得出的结果一致。
