The phrase "an irregular structure" is correct and usable in written English.
You can use it to describe something that does not have a regular or expected form, often in contexts related to architecture, biology, or abstract concepts.
Example: "The artist's latest sculpture features an irregular structure that challenges traditional notions of symmetry."
Alternatives: "an uneven form" or "a non-uniform shape."
That all changed during "Strange Meeting," perhaps Frisell's best-known tune and another musical minefield, with unusually static harmonies and an irregular structure featuring an elongated bridge section.
Molecular organization of the components in solution arranged themselves into an irregular structure.
The minimal trellis module consists of an irregular structure with n sections which can present different number of states.
This module, which has an irregular structure presenting a time-varying number of states, minimizes various trellis complexity measures.
The interest of this second equivalent encoding structure of a classical TC lies in its simplicity and in the opportunity of introducing an irregular structure.
However, as the nanoparticles are surrounded by hydrogel, the pure silver peaks could not be obtained by X-ray diffraction, showing an irregular structure of the polymer.
It is found that there is an irregular energy exchange between the structure and the liquid free surface motion when the center frequency is close to the structure natural frequency.
Weinreb and colleagues showed that the α-Syn protein exists in a native "unfolded" conformation, having an irregular structures [49].
Secondly, lignosulfonate (LS), a byproduct of SPROL in pretreatment hydrolysate, has a unique irregular structure with a non-charged core consisting of cross-linked aromatic chains with all sulfonic acid groups relocated to or near the molecule surface to facilitate interactions with the aqueous surroundings.
When producing theoretical estimates of the effect of irregularity on the vibrational behaviour of a structure, as has been described previously [1 3], one aims to predict the behaviour of a typical irregular structure within the set considered.
A longer irregular structure likely destroyed the cooperativity between subunits leading to the appearance of various subconductance.
