Zusammenfassung: 
By different annealing procedures the (1 x 2) and the (1 x 4) structures on Pt(110) are produced on the clean surface. Both structures are verified by STM and LEED. AES shows very low impurity levels of C, O, S, Si and Ca in both cases. In case of the (1 x 4) structure, Si and/or SiOx signals are not significantly higher than in case of the (1 x 2) structure. The (1 x 2) structure is combined with a perfect `'fish-scale'' pattern of the step structure. The (1 x 4) structure is connected with large flat terraces bound by steep ledges of a height of 30-40 Angstrom. The (1 x 4) structure is identified as a paired-row (1 x 2) structure.
