Crystal structure analyses of one dimensional crystals which are of the stacking of layers and two dimensional crystal which is of the regular array of cylinders were carried out by the small angle scatterings and three kinds of the least-squares methods. One-dimensional crystal: the lamellar phase of polystyrene-poly2-vinylpiridine block copolymer was interpreted by the electron density of the disordered rectangular form. One-dimensional crystal: the stacking of polyethylene single crystals was interpreted by the electron density of the disordered trapezium. Two-dimensional crystal: the cylinder phase of polystyrene-polyethylenebutylene-polystyrene block copolymer was interpreted by the electron density of the disordered cylinder.
