The energy relaxation and kinetic evolution of transient spectra of bacteriochloro- phylls (BChls) in light-harvesting complex LH2 from Rb. sphaeroides 601 were investigated using femtosecond pump-pro
We obtain the co-seismic ground deformation field of the Mani M7.9 earthquake on November 8, 1997 through three-pass differential interferometric processing. Then we get the geometric and kinematics p
To study bistatic scattering from a target at low altitude above two- dimensional (2D) randomly rough sea surface under an electromagnetic (EM) wave incidence at low grazing angle (LGA), a numerical a
面对超市里顾客排起的长长队列,收银员用手持设备不停地扫描着顾客购买的商品,一件,又一件……遇到“扫”不出来的时候经常有,这时就不得不手工输入冗长的商品序列号,在长长的队列中又不时发出顾客不耐烦的埋怨声。也难怪,人在排队等候的时候,往往会感觉时间过得最慢。此时,再熟练的收银员也不禁会手忙脚乱……
In the paper, the hydraulic architecture parameters of Pinus tabulaeformis seedlings (4 years old)were measured by improved flushing method under normal water condition in the green house and the basi
