This is a procedural definition of a simple offset surface at a normal distance distance from the originating surface. The attribute distance may be positive or negative to indicate the preferred side of the surface, the positive side being defined by the cross product of the the direction vectors of increasing u-parameter with increasing v-parameter. 

Migration is both focusing and relocation of the reflection energy. Each zero-offset trace contains reflections that originate at different subsurface points with increasing depth (Fig a) sometimes hundreds of m s away from the surface location. Flowever the reflections are posted at the surface location of the zero-offset trace. Migration compensates for the mislocation due to the bent raypaths. 

Since e > eo, we seek to explain the smaller field in the presence of the dielectric in terms of molecular properties and the way in which they are affected by the electric field. An easy way to visualize the effect is to picture an opposing surface charge-indicated as in Fig. 10.4b—accumulating on the dielectric. This partially offsets the charge on the capacitor plates to a net charge density a - so that Eq becomes E and is given by... 

Reactants must diffuse through the network of pores of a catalyst particle to reach the internal area, and the products must diffuse back. The optimum porosity of a catalyst particle is deterrnined by tradeoffs making the pores smaller increases the surface area and thereby increases the activity of the catalyst, but this gain is offset by the increased resistance to transport in the smaller pores increasing the pore volume to create larger pores for faster transport is compensated by a loss of physical strength. A simple quantitative development (46—48) follows for a first-order, isothermal, irreversible catalytic reaction in a spherical, porous catalyst particle. 

A high-performance biitterllv valve has a disc that is offset from the shaft center line. This eccentricity causes the seating surface to move avv av from the seal once the disc is out of the closed position, reducing friction and seal vv ear. Also Icnovvn as an eccentric disc valve, its advantage is improved shutoff vvliile maintaining high ultimate capacity at a...
