摘要：

The mechanism by which a one-dimensional pattern of traveling waves changes wavelength (i.e., the Eckhaus instability) is studied in a binary fluid mixture. Long-lived transient phase modulations connect states of uniform wave number. The dynamics of wave-number increases and wave-number decreases are found to be qualitatively different due to a strong dependence of the group velocity on wave number. Relevant theoretical models are discussed.
