Forms of vibrations and structural changes in liquid state
Original language description
The forms of vibrations and displacements of particles in amorphous structures have been investigated. The particles, moving on highly non-linear amplitude, are responsible for the creation of disordered structures of amorphous bodies. The non-linear oscillators, even if "few" in concentration, are characterized by unpredictable trajectories in phase space. The non-linear oscillators are fully developed in the liquid state above the crossover temperature Tcr and between Tcr and Tg their number decreasesand under Tg they completely disappear. The interconnection between the linear oscillators forms blocks and plays the most important role in the characteristic time spectra in liquid state. Using the additive properties of elements polarizibilities, thenumber of acoustical units in individual blocks at Tcr is estimated to be about 600 units. The diameter of blocks at Tcr was estimated to be about 1.8 nm. Even if the non-linear high amplitude motions disappear at solidification, the rem
