The phrase "a constant index" is correct and usable in written English.
It can be used in contexts related to mathematics, statistics, or data analysis where a fixed reference point or value is being discussed.
Example: "In our analysis, we used a constant index to measure the performance of the various models over time."
Alternatives: "a fixed index" or "an unchanging index".
Different from previous research, the results demonstrate that the activation energy of asphalt is not a constant index.
The eye parameters used are those of the schematic eye, i.e., a focal length f eye=22.2mm and a constant index of refraction n eye=1.33.
The P-wave dispersion is a constant index in healthy dogs, that is why it can be used for evaluating P wave change in dogs with chronic valvular disease and in dogs with disturbances of supraventricular conduction.
They are featured by (1) volume conservation, (2) interfacial connectivity, (3) power law with a constant power index, and (4) power law with an adaptive power index, respectively.
In this work, we report a generic study by assuming constant index of refraction, temperature and humidity conditions.
In this paper, we have used an ideal 3D isotropic MPC model made from metallic spheres of radius a with a frequency dependent refractive index n1, which are arranged periodically in a background dielectric material with a constant refractive index (n2).
The case N = 1 is clear since a point can be labeled with the constant index 1 only.
Let ((widetilde{M},tilde{g})) be a real ((widetilde{m}+tilde {n}))-dimensional semi-Riemannian manifold, where (tilde{n}geq1), (widetilde{m}> 1) with g̃ a semi-Riemannian metric on M̃ of constant index (tilde{q}in{1,ldots,widetilde{m}+tilde{n}-1}).
Consider a null hypersurface ((M^{n+1},g)) of a ((n+2))-dimensional Lorentzian manifold ((overline{M},overline{g})) of constant index (0
The Cauchy equation can be approximated by a constant refractive index value for longer wavelengths.
First, without detachment of periphyton community, the process of growing mat was addressed under a constant light index, and thus a constant reproduction rate.
