Abstract : From the publications (in many cases from the Figures) it is seen that incommensurate chaines give a surprisingly good account of the following dozen measurements: both components of complex ac conductivities as functions of field and frequency, in both metallic and semiconducting CDW materials; dc characteristics; scaling of ac and dc conductivities; elastic properties - Young's Modules and Q-factor as functions of voltage; bulk oscillations; and both amplitude and phase of both the second and third order mixing properties. In addition, incommensurate chains have been seen to exhibit complete mode locking over the entire range of dc fields and external frequencies. Keywords: Sliding density waves; Sliding potential.
