The structure and dynamic in network-forming liquids has been investigated by mean of molecular dynamics simulation. Four models of silica and alumina liquids with 5500 atoms were constructed in the 2500-3500 temperature range. The structure of the silica and alumina calculated by analysing linkage-cluster (LK- cluster). From the analysis of LK-cluster function FLKCL(r,t) and init-bond function FIB(t), the dynamics heterogeneity (DH) and its origin in network-forming liquid will be clarified. Besides, distribution of mobile and immobile clusters is also investigated via visual method. Influence of temperature on dynamical characteristics of network-forming liquids also discussed in detail.
