Variable virtual bond method

Figure 3. Two alternate methods of describing an a-D-glucose residue using the variable virtual bond method. The bond length, bond angle, and conformation angle for atom 05 are shown as ts, 6s, s-...

In order to obtain a clear, concise, and accurate picture of the surface tmder investigation, there will almost certainly be the need to resort to more than one of the methods described in this chapter. The choice will be influenced by the nature of the material, the type of investigation, and other variables. In adhesive bonding research one thread that runs through virtually all work, be it quality assurance, development, or research, is to relate surface characteristics to a performance measure of the bonded structure. This may he joint strength or toughness but more usually, and particularly for structural adhesive honding, attempts will be made to correlate the surface and interface characteristics with joint durahihty.
