For a substance like K.Se0. as an example, a theory is constructed whichfirst determines the terms coupling the modulated forms of certain selected hardmodes with the modulated soft modes in the thermodynamic potential functionand then deduces that an incommensurate condensation of the soft modes inducesthe selected hard modes to condense incommensurately with wavenumbers ofmodulation equal to -1- or -(P-l-6777) times that of the soft modes, where m takeson 0, 1, 2,= - o and v is a fixed positive integer depending on hard mode. Theamplitudes of modulation are also determined which depend on m as well ashard mode.
