A single-frequency pulsed erbium-doped fiber(EDF) laser with master-oscillator power-amplifier configuration at 1 533 nm is developed. A short-cavity,erbium-dop
The hydrodynamic characteristic of a new rotating stream tray (NRST) was investigated. The tests were carried out using an air–water/oxygen experimental system
Unlike the adverse effect caused by the gelation during crystallization process, gelation of cefpiramide sodium was found to provide ideal product properties, s
