Figure Bl.21.4. Direct lattices (at left) and reciprocal lattices (middle) for the five two-dimensional Bravais lattices. The reciprocal lattice corresponds directly to the diffraction pattern observed on a standard LEED display. Note that other choices of unit cells are possible e.g., for hexagonal lattices, one often chooses vectors a and b that are subtended by an angle y of 120° rather than 60°. Then the reciprocal unit cell vectors also change in the hexagonal case, the angle between a and b becomes 60° rather than 120°. Figure Bl.21.4.

The reciprocal lattices shown in figure B 1.21.3 and figure B 1.21.4 correspond directly to the diffraction patterns observed in FEED experiments each reciprocal-lattice vector produces one and only one diffraction spot on the FEED display. It is very convenient that the hemispherical geometry of the typical FEED screen images the reciprocal lattice without distortion for instance, for the square lattice one observes a simple square array of spots on the FEED display. [Pg.1768]

Thus, the inverse collision gives rise to the same particle velocities as those with which the corresponding direct collision is started. [Pg.13]

Fig. 12.2 (a) Polyhedral view of [MnCglAIgGe]. (b) Ball-and-stick view of the shell structure around the [MntglAIgGe] polyhedral cluster. The top and side views are along (001) and (no), respectively. In (c) a Mackay icosahedron in a-MnAI(Si) is oriented along the corresponding directions. [Pg.186]

The threshold energies for these processes correspond directly to the electron affinity (EA) or ionization energy (IE). [Pg.216]

The desired independence between the variables of the different analytical signals corresponds directly with the selectivity of the analytical system (Kaiser [1972] Danzer [2001], and Sect. 7.3). In case of multivariate calibration, the selectivity is characterized by means of the condition number... [Pg.185]

The setpoint indicator, located in the center of the upper half of the controller, indicates the setpoint (desired value) selected for the controller. The scale may be marked 0% to 100% or correspond directly to the controlled variable (e.g., 0 - 1000 psig or -20°F to +180°F). [Pg.156]

The monolayer stability limit is defined as the maximum pressure attainable in a film spread from solution before the monolayer collapses (Gaines, 1966). This limit may in some cases correspond directly to the ESP, suggesting that the mechanism of film collapse is a return to the bulk crystalline state, or may be at surface pressures higher than the ESP if the film is metastable with respect to the bulk phase. In either case, the monolayer stability limit must be known before such properties as work of compression, isothermal compressibility, or monolayer viscosity can be determined. [Pg.54]

For these complexes, the first band corresponds directly to lODq. If all three of the spectral bands are... [Pg.655]

Figure 1.2 (a) Lowest s- and p-type valence atomic orbitals of rare-gas atoms, showing radial profiles (left) and contour plots (right). (Each plot is 3 A wide, and only the four outermost contours are plotted see note 26.) (b) Similar to Fig. 1.2(a), for valence 4s, 4p, and 3d atomic orbitals of Kr, corresponding directly to the surface plots of Fig. 1.1. [Pg.11]

We ve already said that an attribute need not correspond directly to stored data in an implementation.2 A client is described as having a balance, but its implementation could be anything from a number tallied by hand in a ledger to a macro that summed selected purchase orders in a database. [Pg.84]

At the lowest level, class diagrams can correspond directly to program code attributes and associations turn into pointers or (in languages such as C++) contained objects. Many 00 design tools provide the means to turn a class diagram into skeleton code and vice versa. However, we should be careful not to use this facility too readily it is useful only at the very bottom layer of design. [Pg.232]

Another implementation of a queue is based on a linked list. There is not necessarily any variable that corresponds directly to the model s length, but you can retrieve it by counting the nodes. [Pg.246]

The ( ) suffixes distinguish the implementation. The first thing a reviewer might notice is that the classes I have written don t seem to correspond directly to the classes mentioned in the specification. Their attributes are different, and so on. We are doing object-oriented design, says the reviewer. Your code should mirror the spec. It says so in 50 different textbooks. ... [Pg.261]

Each state in a state chart should be documented with a condition stating when it is true. In this case, isBIank corresponds directly to the attribute of that name isSum == (content Sum) ( the content attribute is of type Sum ). [Pg.294]

A type specification denotes a set of objects All objects that meet that specification are members of that type. Some ways of combining type specifications correspond directly to operating on the corresponding sets of objects join does not. [Pg.352]
