Basically, the crater diameter can be theoretically linked to the crater depth according to the model given by Bitter et al., which is presented in more detail in the next section.
where [C.sub.d], Crater depth; R, Particle radius; r, Crater radius.
More important, the originality of the structure, pattern, contour and texture of the irradiated crater depth will be sustaining from any physical and chemical distortion before proceed to the sample analysis.
This might be due to almost of the top coating for sample B8 is not removed at 210-250 J/[cm.sup.2], but conversely removed at the centre of the crater depth obtained at 260-300 J/[cm.sup.2] as shown in Appendix 1.
The largest impact crater depth values under different pipeline pressure are shown in Figure 7.
Figure 8 shows the largest impact crater depth under different impact velocity.
The same trend for craters on Titan was calculated using estimates of the crater depth
from images made by Cassini's radar instrument.
A stylus profilometer (KLA Tencor Instruments, Milipitas, CA) was used to monitor the mass loss (crater depth) from the exposed surfaces of the polished polymer samples.
To convert each measured surface profile into a single data point, the average crater depth was calculated over the middle 3 mm (0.12 inch) of each measured crater.
However, as impact angle decreases, so does crater depth
(Gault and Wedekind 1978; Pierazzo and Melosh 2000).
* The tool wear data showed different trends, the crater depth
increased as the cutting surface speed increased.
He also uses sometimes outdated information, including crater depths
and peak heights, from the classical observers of the 19th century.
