Tuning the Raman excitation laser to an electronic absorption line increases the Raman scattering cross-section dramatically and leads to resonant Raman scattering, which can be amplified by thousands of times over the nonresonant scattering.
The numerical result analysis indicates that using combined optimization method of lattice and exhaustion to design ash dam cross section can achieve more stable result and decrease the time consuming of calculation, which improve the performance dramatically.
Tube architecture varies dramatically in different organs and different species, ranging from tubes formed by several cells constituting the cross section, tubes formed by single cells wrapping an internal luminal space or tubes that are formed within a cell.
A really nice cross section".
"You want a cross section.
"It draws a cross section.

It's a really wide cross section".
