As a structural model of liquid, a crystal threaded by fine network of dislocations is proposed. The main prepositions characterizing the model system are the elastic distortion of the mesh material in bulk rather than the local distortion at the core of the constituent dislocations, the frequency modulation for the transversal shear waves due to the anharmonicity of the potential, and the introduction of degenerated non-harmonic shearing translations. With the prepositions, the model system is shown to display a kind of first order phase transition between an imperfect crystal as representative for the liquid phase and a perfect crystal as representative for the solid phase. The order of magnitude of the frequency modulating coefficient, the only adjustable parameter, is estimated under comparison with the experimental data of noble metals.
