Subsurface growth, model

The presented nucleation and growth model implies that the geometry of calcite-cemented zones is controlled by the original distribution of biogenic carbonate, and prediction of the geometry of calcite cementation in subsurface reservoirs therefore largely depends upon an understanding of the depositional environment. 

Todorov et al. [73] made equivalent assumptions in the modeling of a-CN.v film growth within another context. They focused their attention on the calculation of the collision cascade details following subsurface penetration of and N+ ions... 

The evolution and decomposition of metal clusters in the polysiloxanes has been quantified (49), and a diffusion-plus-reaction model for cluster growth at the surface and in the near subsurface region of a polymer film has been developed (SO). Collectively, the studies show that organometallic chemistry at the polymer/vacuum interface can have profound effects on both the dynamics of polymer chains at the surface and the evolution of low nuclearity clusters (SO, 51). 

The four wear mechanisms described in this section all lead to Archard s law, but the physical interpretation of the wear coefficient differs. In the adhesive wear model the wear coefficient expresses the probability that an adhesive junction leads to formation of a wear particle. In the abrasive wear model the wear coefficient depends only on the geometry of the abrasive. The wear coefficient in delamination wear characterizes the critical number of cycles leading to fatigue fracture of microscopic subsurface cracks. Finally, the wear coefficient in oxidative wear includes the growth constant and the critical thickness of a surface oxide film.
