The phrase "a certain width" is correct and usable in written English.
It can be used when specifying an unspecified or approximate measurement of width in various contexts, such as design, construction, or description.
Example: "The table should be designed to fit in the space with a certain width to ensure it does not overcrowd the room."
Alternatives: "an unspecified width" or "a particular width".
"Everything about him has a certain width to it," Epstein writes.
A design method of a cycloidal transmissive Fresnel solar concentrator which can provide a certain width focal line was presented in this study.
We are unable to say that the requirement that entries shall have a certain width beyond the tracks, as prescribed by this statute, would not promote the safety of the employees engaged in that work.
A certain width of the intermixing layer is probably formed between BFO films and individual substrate which is attributed to mutual diffusion in the interface zone during annealing process.
The factor, which reflects the variation of bond strength due to change of the width of concrete substrate for a certain width of plate, is commonly derived from plate-concrete joint tests (also known as pull tests) indirectly.
Or, the other way to say it, if you want in matrix form is delta u delta v is, sorry, approximately equal to matrix |u sub x, u sub y, v sub x, v sub y| times matrix |delta x, delta y|, OK? So, if we look at that, what it tells us, in fact, is that if we take a small rectangle in xy coordinates, so that means we have a certain point, x, y, and then we have a certain width.
In this work, groove-textured surfaces with a certain widths and pitches are manufactured on flat cast iron samples.
The suggested layout consisted of a double glass window, separated by a gap of certain width, filled with a PCM of certain fusion temperature, as shown in Fig. 3.
The idea is to crop a band of certain width around the boundaries of the image.
The in-plane thermal conductivity exhibits a minimum for a certain interfacial width, while the cross-plane thermal conductivity increases modestly in increasing the width of the interfaces.
It is, for instance, possible that when increasing the notch width around the test tone frequency, the lateral inhibitory band of the sharp notched-noise edge at a certain notch width reaches neurons which normally inhibit neurons whose CF is near the target tone frequency, consequently allowing more neurons to respond to the test tone.
