You can use it when referring to a significant quantity of distinct parts or divisions within a larger context, such as a document, report, or book.
Example: "The report consists of a large number of sections, each addressing different aspects of the research findings."
Alternatives: "a considerable amount of sections" or "many sections."
In addition, the body consists of a larger number of sections than before (McMillen et al., 2008), in order to minimise the effect of taper (which is ignored in the Taylor approximation).
A large number of composite sections, which could represent the conventional cross-section of composite plate girders with medium spans, are designed along with various combinations of material strengths.
A large number of samples (sections of exposed rebars) were collected from buildings up to 96 years old, and weight loss measurements, tensile testing and fractographic analysis were carried out.
The location of the experiment should ensure on one hand the constant function of the recording device, and on the other hand the presence of a large number of curved sections.
One possible explanation could be that a large number of C-sections performed at hospitals in Beirut are elective- or not medically indicated.
Our group has measured a large number of fragmentation cross sections, intended to be used as input to, or for validation of, NASA's radiation transport models.
Tomographic measurements have been carried out in a large number of packing cross sections situated at different heights between the top and the bottom of the packed column, giving access to the evolution of axial profiles of liquid hold up and of gas liquid interfacial area as a function of the operating conditions.
In these papers the results were based on measurements taken on a 3D reconstruction of the material, obtained by means of a large number of 2D tomographic sections of a real sample.
To obtain a more quantitative picture of the ratio of icosahedral to elongated carboxysomes in the mutant and in the wild type, carboxysomes were counted in a large number of cell thin sections in random fields of vision, regardless of the orientation in which cells and inclusions were cut (Table 1).
