On the other hand, the sodium distribution coefficient is still poorly known [8] and as a minor element acting much more fluid than the Sr during diagenesis (Veizer, 1983b).
The selectivity is shown in Figure 3, while the distribution coefficient is shown in Figure 4.
Furthermore, as transport models incorporate the metal distribution coefficient (and most usually the linear distribution coefficient) into the overall retardation factor, so the study suggests areas for research and experimentation that may be key to incorporate curvilinear distribution coefficients into the transport models instead of a linear partition coefficient.
The partitioning of the RN between the solid and the liquid phase is described by the distribution coefficient ([K.

We adjusted other parameters needed to calibrate the model--such as tissue distribution coefficients, metabolism and excretion parameters, and the blood:air distribution coefficient ([H.
A plastic stress distribution coefficient was used, since it was believed to represent better the actual stress distribution in the failing parts.
As explained below, the distribution coefficient v is the proportion of an unobservable "residual" which is distributed to capital managers, while the retention coefficient [Alpha] is the proportion of an observable flow of property return which is retained by capital managers.
