The phrase "a long duration time" is not correct and sounds awkward in written English.
It is typically used when referring to an extended period or length of time, but the wording is redundant.
Example: "The project requires a long duration time to complete, so we need to plan accordingly."
Alternatives: "an extended period" or "a lengthy duration".
It also appears in a long duration time scale for ISHM systems [21] Fig. 4. Open image in new window Fig. 4 ISHM block diagram [21].
In contrast, the mature forest, which contained many large standing trees and large amounts of deadwood, experienced a high-intensity fire over a long duration time, resulting in surface or deeply burnt deadwood.
Thus, under the growth temperature of InN (550°C), the pulsed deposition of In for a long duration time may form a thick liquid In layer on the surface.
Approximately one month before the megathrust earthquake, Fig. 4(b) shows that the dominant slip velocity for | Strike | < 40 km becomes higher than 10Vp1 (orange) and is sustained over a long duration time (more than one month).
It is remarkable that using these two types of complexing agents and annealing them at a relatively high temperature of 950°C with a long duration time of 36 h, the crystallite sizes of both samples are still very small as can be seen from the FESEM micrographs of Figure 4a,b for samples MgO-OA and MgO-TA, respectively.
Because the estimation (12) is a pure time-domain method that uses a finite time window width, it does not require a long-duration time window as do methods using a Fourier transform (Langston 2007b) or an analytic signal with a Hilbert transform (Langston 2007c).
Since a fairly long duration time is required, the pre-stretched technique has been chosen.
The amplified long period ground shaking in the Taipei basin had a very long duration time of about 40 s, which lasted from 35 to 80 s.
For higher particle concentration, the particles stuck on the surface and the nanoparticles with a relatively long duration time would deteriorate the heat transfer.
The CBL thickness tends to increase over long duration time in the former configuration, while it converges to a steady-state value in the latter.
In case unit of analysis issues arise in studies of long duration, time frames will be defined as 1, 3 and 6 months to reflect short-term, medium-term and long-term follow-up, respectively.
