Abstract: Based on the method of deriving the second rank algebraic formulas of single phasespresented in previous paper, the second rank algebraic formulas of all orthorhombic spacegroups, includin g triclinic and monoclinic, have been derived.Thus a simple and complete table is presented for all the 74 space groups in triclinic, monoclinic and orthorhombiccrystal systems.The structure eminvariants of three crystal structures with orthorhombicspace group have heen estimated by corresponding algebraic formulas, the results are quitegood.The feature of in the application of algebraic method lies in that one type ofphase could be estimated by different kinds of second rank algebraic formulas and severaltypes of phases could be estimated by one kind of second rank formulas.

Key words: crystal structure, second rank algebraic formula, orthorhombic space group
