The phrase "exponential relation" is correct and usable in written English.
For example, one can say, "The exponential relation between human population growth and carbon emissions is evident."
Many subsequent studies using borehole log data, core data, and laboratory measurements have confirmed that an exponential relation is good approximation for relating resistivity to porosity (Jackson et al. 1978; Swanson 1979; Hilfer 1991; Ioannidis et al. 1997).
The NDVI was fitted to the canopy chlorophyll content using an exponential relation.
However, a strong exponential relation between DRI and the brittleness of B8 was found.
Besides, there exists a precise exponential relation C∝k−0.5 at Rc=12 Å.
Figure 6 The negative exponential relation between the optical bandgap and the irradiation dose.
An exponential relation between Rq and Qdiss is found by evaluation of the three-dimensional roughness.
For all samples, exponential relations (R 2 > 0.889) were found to apply, corresponding to first-order rate equation.
Rigorous bounds (Voigt Reuss and Hashin Shtrikman bounds) are given as well as model relations for prediction and fitting purposes (dilute approximations, power-law relations, exponential relations, Coble Kingery relations and new relations recently proposed by the authors).
It is well known that certain exponential relations play a fundamental role in the proofs of asymptotic results for independent and weakly dependent random variables.
The permeability coefficient P, the diffusion coefficient D, and the solubility coefficient S can vary as a function of temperature, and exponential relations can express these relations: Open image in new window (4 where E p is the activation energy of permeation, E d the activation energy of diffusion, and Es the heat of solution that have in SI units the dimension [kJ/mol].
The degradation curves of phenol by solar photo-Fenton reaction seem to be well fitted by mono-exponential relation, which can be appropriate to be described by pseudo-first order kinetic model.
