The phrase "a large annulus" is correct and usable in written English.
It can be used in mathematical or geometrical contexts to describe a specific shape or area that is ring-like and has a significant size.
Example: "In our study of geometric shapes, we focused on a large annulus that was formed between two concentric circles."
Alternatives: "a wide ring" or "a broad annular region".
The large mass flow of the steam needed to satisfy the pump's demand for the driving power causes the volume of the outlet steam mass flow to increase significantly, which results in a large annulus area and, consequently, in high blades of the last turbine stage.
It is tempting to speculate that the disorder within the residues 19 29 would impart the ability for a rotational motion to MltC to sweep out a large annulus of cleared peptidoglycan per each molecule of enzyme, which would enable insertion of a large assembly such as that of the flagellum.
In contrast, placement of a small valve in a large aortic annulus has been shown to be associated with increased risk of post-procedural aortic regurgitation [16] and device dislocation [17].
These features are the result of the required large annulus areas that are required, which make last-stage long blade developments difficult.
To decrease the manufacture difficulty in China, a novel fiber structure is presented, defined as annular chirally-coupled core (ACCC) fiber, replacing the small side core by a larger side annulus.
The two-dimensional TEE from the modified four-chamber view clearly showed a large vegetation on the annulus of the aortic valve which protruded into the RA chamber (Fig. 3).
Placement of a large valve in a small annulus might result in rupture or AV block [15].
In both non-diapausing and diapausing animals, the presumptive sensory epithelium initiates development, after pupation, with two zones of high density cells lining the proximal and distal borders of each annulus and a large field of low density cells filling the middle annular regions.
Non-contrast CT typically shows a large calcified mass in the region of the posterior mitral annulus extending to the adjacent mitral valve.
Rates of liquid solid mass transfer were measured at the inner surface of an annulus by an electrochemical technique which involves measuring the limiting current of the cathodic reduction of K3Fe CN 6 in aqueous solution with a large excess of NaOH under single and two phase flow using an annulus packed with inert spheres.
In this work, a large number of experiments are performed to measure the heat transfer reduction and fouling resistance of CaSO4 aqueous solutions in a vertical upward annulus under subcooled flow boiling condition.
