N2 - The compactification of the 26-dimensional closed bosonic string into 10-dimensional superstrings is analyzed in the covariant formalism. A mechanism is proposed for the emergence of the SO(9,1) Neveu-Schwarz-Ramond fields and the superghosts together with negative-metric states from the Euclidean compactified bosonic degrees of freedom. It is shown that, after compactification, there appear some extra fields which form an OSp(3,36) supermultiplet. The decoupling of these extra fields is studied in analogy with the no-ghost theorem in the covariant string theory.
