| Abstract: | Presents that two-type ordinals have the following property:for every well-ordering two-type class structure［A，R］there exists a unique two-type ordinal B such that ［A，R］is isomorphic to ［B，E］.Particularly, for every well-ordering conlomerate structure［A，R］there exists a unique two-type ordinal number α* that ［A，R］is isomorphic to ［α*,∈］.Therefore, we know that in an isomorphism sense well-ordering two-type class stuctures are two-type ordinal structures. |
