The slow variation of

oscillatory part which one can regard as a shift in resonant frequency of the

normal modes; the other represents an exchange of energy between sets of

waves.

The slow variation of

**amplitude**may itself be divided into two parts: one is anoscillatory part which one can regard as a shift in resonant frequency of the

normal modes; the other represents an exchange of energy between sets of

waves.

**amplitude**of the test wave k, ismuch larger than the

**amplitudes**of all other background waves, the secondderivative of J(k) is negative so that the wave begins to decay in
