Synthesis of A Novel ABC Triblock Copolymer with a Rigid-Rod Block in the Middle by Two-step Atom Transfer Radical Polymerization,谢鹤楼,张海良,A series of novel amphiphilic ABC type coil-rod-coil triblock copolymers poly(ethylene oxide)-block-poly{[(4-met
The feasibility of fenestration operation in middle ear bone with pulsed infrared laser is evaluated. Healthy male New Zealand rabbits in vivo are used in the experiment. Middle ear mastoid bone of animal model is completely exposed with conventional
We propose a continuous-wave (CW) middle infrared (MIR) and long infrared (LIR) dual-band laser for the calibration and effect research of infrared detecting and imaging systems. A total output power of 18 W is achieved by the proposed dual-band lase
