The phrase "a varying length" is correct and usable in written English.
It can be used to describe something that changes in size or duration, often in contexts related to measurements, time, or dimensions.
Example: "The cables come in a varying length to accommodate different installation needs."
Alternatives: "a fluctuating length" or "a diverse length".
Each cable which consists of an inclined section and a varying length vertical section is modeled as an axially moving string with coupled transverse-longitudinal nonlinear vibration.
In this study, we synthesized three series of oroxylin derivatives by connecting a nitrogen-containing hydrophilic, heterocyclic ring to the C7-OH via a varying length of carbon chain.
Last, a varying length of the vocal folds (Figure 8) seems to have a relevant effect on frequency modulation ((overline {sigma }_{f} approx 10%%)) when the length variability goes above a certain threshold ((overline {sigma }_{l} > 1.3 %)).
Localised Reiki treatment involves the practitioner's hands being held on or near a specific part of the body for a varying length of time.
In order to identify some of the effects of intronic sequences flanking Exon 10 on the splicing of the region between Exon 9 and Exon 11, minigene constructs containing Exons 2 9, a varying length of Intron 9, Exon 10, an shortened Intron 10, and Exon 11 were constructed and expressed in Human embryonic kidney (HEK) 293 cells (Figure 2).
Third, for our evaluation of the ECG parameters from the whole session, we allowed recordings to have a varying length, rather than a standard length.
From this theoretical point of view, they defined a crisis as a period of varying length in which the system elements become increasingly unstable.
Images of faces and scenes, each selected from a set of 10, were flashed before the subjects sequentially, with each displayed for six-tenths of a second, followed by a pause of varying length before the next was displayed.
It is commonly observed that trypanosomes, belonging to a so-called resistant strain, disappear quickly from the blood stream following treatment, and the only (but very important) difference with a non-resistant strain is that they reappear after a period of varying length.
It may be lying in an extrasynovial position in a tunnel in the fibrous capsule, or it may have a mesentery of varying length.
The longitudinal-transverse vibration of a rope of varying length is considered.
