The performance of polymers in increasing the E of wood and in perturbing the complex higher order structure of wood has been pursued by taking into consideration the situation of the interaction of polymers with wood as it appeared in the change of the dynamic viscoelastic and the dielectric patterns of WPG systems. 

Dynamic models for ionic lattices recognize explicitly the force constants between ions and their polarization. In shell models, the ions are represented as a shell and a core, coupled by a spring (see Refs. 57-59), and parameters are evaluated by matching bulk elastic and dielectric properties. Application of these models to the surface region has allowed calculation of surface vibrational modes [60] and LEED patterns [61-63] (see Section VIII-2). 

Step 11. If no additional metallisa tion layers are required, the substrate is covered with a passivation layer. If additional levels of metallisa tion are to be added to the stmcture, a blanket layer of a intermetal dielectric (IMD) is deposited. The resist is deposited, patterned (mask 5), and vias down to the Al in the first metal layer are etched. Steps 10 and 11 are repeated to form the second metal layer.

The pattern of interaction between metastable atoms of rare gases and a semiconductor or dielectric surface is not yet clear, the literature data in this field are incomplete and uncoordinated, a fact that is primarily associated with the lack of convenient techniques suitable for studying these systems.
