Triangular region

Fig. XVII-18. Contours of constant adsorption energy for a krypton atom over the basal plane of graphite. The carbon atoms are at the centers of the dotted triangular regions. The rhombuses show the unit cells for the graphite lattice and for the commensurate adatom lattice. (From Ref. 8. Reprinted with permission from American Chemical Society, copyright 1993.)...

Fig. 4.1. Interference of incoming and the reflected X-ray waves inthe triangular region above a flat and thick reflecting substrate. The strength ofthe electromagnetic field is represented on the gray scale by instantaneous crests (white) andtroughs (black). Inthe course of time, the pattern moves from the left to the right [4.21].

Figure 5.12. The chemical source term for Y2x, will be non-zero in the triangular region bordered by the line Y2co = 0 and the two lines found from setting h = 0 and h2 = 0. The mixing line corresponds to the upper limit for y2co in the range 0 < < and results from micromixing between fluid elements at (0, 0) and ( max> Y2lmK).

The triangular region can be expressed analytically in terms of two parameters fmax = (5-203)... 

Having established the form of the reaction rate function for F2oo, we can now look at its limiting behavior when k2 - oo. In this limit, all points in the triangular region where the reaction rate is non-zero (Fig. 5.12) will be forced to the upper boundary. Thus, in the... 

The triangular region in Fig. 5.12 can also be used to analyze the effect of micromixing in semi-batch reactors wherein the stream containing B is slowly added to a reactor initially containing only A. In this reactor, the mean mixture fraction is an increasing function of time ... 

Corresponding to each point in the triangular region of the L,L2 plane shown in Fig. 12.8 there is a unique ellipsoid, and conversely. It would be an... 

Figure 12.8 Each point of the triangular region corresponds to a unique ellipsoid, and conversely.

The phase diagram shown in Figure 8.7 is simpler than many other ternary phase diagrams inasmuch as only one liquid crystal phase exists, and there are no three-phase triangles. By contrast, the water-decanol-sodium-caprylate phase diagram at 20°C shows 5 different liquid crystal phases and 10 triangular regions, in each of which 3 different sets of phases are in equilibrium. 

Figure 7. Solution diagrams for spheres with adsorbed polymer. Left for oxide particles In water the triangular region marked gel" Is a single phase which separates from the solvent (upper part of the flocculation region, above the o.f.c.) or from a dispersion of excess spheres (below the o.f.c.). The boundary between stabilization and flocculation corresponds to the saturation of the surfaces with polymer. Right for surfactant micelles, all these boundaries are replaced by a stoichiometry which divides a region containing necklaces only from a region containing necklaces plus excess micelles (no phase separation).
