A quantity is always associated with the context of measurement (i.e. the thing measured, the measured value, the accuracy of measurement, etc.) whereas the underlying quantity kind is independent of any particular measurement. Thus, length is a quantity kind while the height of a rocket is a specific quantity of length; its magnitude that may be expressed in meters, feet, inches, etc. Examples of physical quantities include physical constants, such as the speed of light in a vacuum, Planck's constant, the electric permittivity of free space, and the fine structure constant. </p> <p class="lm-para">In other words, quantities are quantifiable aspects of the world, such as time, distance, velocity, mass, momentum, energy, and weight, and units are used to describe their measure. Many of which are related to each other by various physical laws, and as a result the units of some of the quantities can be expressed as products (or ratios) of powers of other units (e.g., momentum is mass times velocity and velocity is measured in distance divided by time). These relationships are discussed in dimensional analysis. Those that cannot be so expressed can be regarded as "fundamental" in this sense.</p> <p class="lm-para">A quantity is distinguished from a "quantity kind" in that the former carries a value and the latter is a type specifier.</p> Quantity A <b>Quantity Kind</b> is any observable property that can be measured and quantified numerically. Familiar examples include physical properties such as length, mass, time, force, energy, power, electric charge, etc. Less familiar examples include currency, interest rate, price to earning ratio, and information capacity. Quantity Kind A <i>Quantity Value</i> expresses the magnitude and kind of a quantity and is given by the product of a numerical value <code>n</code> and a unit of measure <code>U</code>. The number multiplying the unit is referred to as the numerical value of the quantity expressed in that unit. Refer to <a href="http://physics.nist.gov/Pubs/SP811/sec07.html">NIST SP 811 section 7</a> for more on quantity values. Quantity value A unit of measure, or unit, is a particular quantity value that has been chosen as a scale for measuring other quantities the same kind (more generally of equivalent dimension). For example, the meter is a quantity of length that has been rigorously defined and standardized by the BIPM (International Board of Weights and Measures). Any measurement of the length can be expressed as a number multiplied by the unit meter. More formally, the value of a physical quantity Q with respect to a unit (U) is expressed as the scalar multiple of a real number (n) and U, as \(Q = nU\). Unit Crystalline Material The crystallographic defect is a lattice irregularity that has one or more dimensions on the order of an atomic diameter. Crystallographic Defect A crystal structure is described by the lattice geometry and atomic arrangements within the unit cell. Crystal Structure Das mathematische Konzept zur Darstellung der Periodizität eines Kristalls. Ein Gitter definiert eine periodische Anordnung von einem oder mehreren Atomen.

Vector Component of Basis An elementary unit (length order of lattice parameter) of lattice translation. The basic notion of the Burgers vector comes from the closure failure of an initially perfect lattice due to the existence of dislocation. The magnitude and direction of closure failure are characterized by the Burgers vector. Eine elementare Einheit (Längenordnung der Gitterparameter) der Gittertranslation. Der grundlegende Begriff des Burgers-Vektors leitet sich aus dem Versagen der Schließung eines ursprünglich perfekten Gitters aufgrund der Existenz von Versetzungen ab.

The segment is a part of a line bounded by two distinct end points and may contain points on the line between its endpoints. Segment die Strecke 1 Die Formfunktion ist die Funktion, die die Lösung zwischen den an den Netzknoten erhaltenen diskreten Werten interpoliert. Bei der diskretisierten Versetzung bestimmt die Formfunktion die Form eines Segments und letztlich die Form der Linie. Beispiele für Formfunktionen, die zur Diskretisierung der Versetzung verwendet werden, sind kreisförmig, elliptisch, spiralförmig, linear, kubisch und quintisch. The shape function is the function that interpolates the solution between the discrete values obtained at the mesh nodes.
