The phrase "a defined surface" is correct and usable in written English.
It can be used in contexts related to geometry, physics, or design where a specific surface is being described or referenced.
Example: "In the experiment, we focused on a defined surface to measure the effects of pressure accurately."
Alternatives: "a specified surface" or "a designated surface".
RFID can be used to locate or guide autonomous entities, such as robots or people, within a defined surface.
This requirement can be fulfilled when measurement standards with a defined surface structure in accordance to the later obsessed application are used.
Embedding ceramic particles with a negative thermal expansion coefficient into a metallic corrosion resistant coating can establish a reversible thermal activation of a defined surface microstructure with the aim of having a shark-skin at high temperatures (in use) and self-cleaning at low temperatures (out of use).
The GEMSIS-RB model calculates trajectories of the weighted particles and estimates flux distributions on a defined surface at any arbitrary position by counting the weighted particles passing through the surface.
As a basic principle, the release of metal should remain 'As Low As Reasonably Achievable (ALARA).' An SRL specifies, the maximal amount of metal ions (in mg) may be transferred from a defined surface of the contact material to the food (in kg) or food simulant.
Therefore, the hypotheses on which the model is based may not completely describe the real process, e.g. the reaction can occur along a diffused front instead of doing it on a defined surface between the unreacted solid, the ashes or the fluid layer, so it corresponds to an intermediate behavior between the two mentioned models and controlling stages [48].
By September 30, the shear and cooler waters weakened Melissa to a tropical depression with a poorly defined surface center.
Upon formation, the system consisted of a very broad subtropical low, as well as a poorly defined surface circulation.
These bulk alloys were prepared in UHV to obtain a well defined surface composition of 75 at.% Pt and 25 at.% Co and Ni, respectively.
The method relies on the generation of a spatially defined surface chemistry comprising protein adsorbing and non-adsorbing areas that allow control over the adsorption of cell-adhesive glycoproteins.
When we form a mental image a quasi-picture or surface representation is constructed, on the basis this stored information, on a functionally defined surface that Kosslyn calls the visual buffer.
