The phrase "a specified surface" is correct and usable in written English.
It can be used in contexts where you need to refer to a particular surface that has been defined or identified in some way.
Example: "The experiment was conducted on a specified surface to ensure consistent results."
Alternatives: "a defined surface" or "a designated surface".
It is worth mentioning that while modeling the boundary layer flow and heat transfer of stretching/shrinking surfaces, the boundary conditions that are usually applied are either a specified surface temperature or a specified surface heat flux.
Nadir angle shows the spatial relation between a specified surface point (point P in Fig. 1) and the extraction point in the coal seam that influences surface point P to subside the most amount (point Z).
(2) Nadir angle shows the spatial relation between a specified surface point (point P in Fig. 1) and the extraction point in the coal seam that influences surface point P to subside the most amount (point Z).
We linearize the relation between the parameters (density and velocity profiles) of a layered fluid subject to a specified surface point traction and the precitically reflected part of its surface motion.
Laser parameters for the glazing and surface alloying processes were optimized, the criteria being a specified surface finish and integrity.
The new results are applied to certain problems involving neither a specified surface temperature or heat flux, such as convection radiation and catalytic surface recombination.
The small volume of the examined drop and the precision of Hamilton's syringe allowed us to place the drop on a strictly specified surface on the plate.
On a Fe(1,2)@W(1 1 1) surface, the barrier to form ethylene is only 0.84 eV, the least of all specified surfaces.
We suggest that, as nanoscale materials synthesis techniques improve, it will become feasible to reproducibly prepare NSAs with highly specified surface structures, resulting in the design and manufacture of a wide variety of such materials for use in fuel cells and in an ever-increasing range of catalytic applications.
Free design variables are identified and various design constraints are formulated, which must be satisfied so that an optimum design obtained is executable in the field using the specified surface equipment (pump, tubing, etc).
The decomposition aims at minimizing machining time within the constraints of the specified surface roughness and tolerance, and machine tool safety.
