It can be used in contexts discussing measurements or characteristics of a substance or phenomenon, particularly in scientific or technical writing.
Example: "The study revealed a density of the material that was significantly higher than previously recorded."
Alternatives: "a concentration of the" or "a level of the".
In addition, we evaluate a density of the volume forces inside the surface layer.
The thermal dependence of S is consistent with non-degenerate conductivity and its value implies a density of the order of magnitude of ~1020 cm−3 (see below).
The reason for increasing of the surface free energy as the crosslinking proceeds is increases of a cohesive force and a density of the BR.
The amount of agreements on the statements inputted by the discussion commanders is represented as a density of the color of the nodes.
The shift in the resonant frequency can be translated into a density of the fluid or into the presence of macro/micro molecules.
These clumps will collapse further owing to self-gravity and finally form planetesimals that have a density of the order of the solid density of silicates (but somewhat lower because of the porosity).
Actually, x is A-statistically convergent to L if and only if, for every ε > 0, δ A ( k ∈ N : | x k − L | ≥ ε ) = 0, where δ A ( K ) denotes the A-density of the subset K of the natural numbers and is given by δ A ( K ) : = lim n ∑ k = 1 ∞ a n k χ K ( k ) provided the limit exists, where χ K is the characteristic function of K.
"A Density of Souls," the first novel of Christopher Rice, 21, son of Anne, is described by his editor at Talk Miramax Books, Jonathan Burnham, "as 'Dawson's Creek' crossed with Donna Tartt," the novelist.
