To improve the performance of double clad high power fibre lasers, inner cladding design plays a significant role.A triangular inner cladding and silica structu
We have investigated the persistent current in a mesoscopic ring with a side-coupled quantum dot. The problems are probed by using the one-impurity Anderson Ham
Yield strengths in unpassivated and 530 nm TiN passivated Cu films deposited on Ti, high-speed steel and Ni substrates have been measured by x-ray diffraction (
In this paper we have studied the phased t U Hubbard model. Using the constrained path Monte Carlo method,we investigated the effects of phase factor on pairing
磷素作为甘蔗生长发育的必需肥料元素之一,在甘蔗生长发育的各个阶段起着至关重要的作用,如适量施磷不仅可以促进甘蔗根、茎、叶等组织器官的形态建成,而且可以有效改善甘蔗茎径、有效茎数、单茎重,进而贡献于甘蔗产量的增加。研究者们对我国多个蔗区调查研究发现,大部分蔗区的有效磷含量仍处于中等以下水平,且蔗区的磷素利用效率也相对低下,仅为6.7%-15.3%。近年来,人们通过对一些模式植物拟南芥、水稻进行研究发
Electron-induced Hf-, W-L-shell partial, total production cross sections, mean ionization cross sections and HfLa-shell ionization cross sections (at two energi
We report on an optical interference method to fabricate arrayed holes on metal nickel foil and aluminum film deposited on glass substrate by means of five-beam
An improvement of the Peierls equation has been made by including the lattice effects. By using the non-trivially gluing mechanism for the simple cubic lattice,
SrTiO3 (STO) thin films were deposited on p-Si(100) substrates at various substrate temperatures from 300℃to 700℃ by radio frequency (RF) magnetron sputtering
Variational calculations are carried out with a multiconfiguration-interaction wavefunction on the 1s22p2p 1De and 1s22p3p 3pe states to obtain the energies inc
