Phase evolution, microstructures and the optimal <italic>x</italic> value of ceramics with nominal composition Li<sub>2x</sub>(Zn<sub>0.95</sub>Co<sub>0.05</sub>)<sub>2−x</sub>SiO<sub>4</sub> were investigated.
With the development of modern radar and communication systems, frequency sources with high spectrum purity, broad band low phase noise becomes more important. A Ku synthesizer function single sweep output is presented in this paper. Commercial chips are selected according to design parameters. theoretical analysis phase-locked loop (PLL) also conducted. The source controlling software designed achieve such functions as lock detect, mode selection. measured span Ku-band 15GHz~16.5GHz, a step...
Purpose This paper aims to reveal the effects of copper third body on different matrix friction materials with a novel experimental way called “exogenous powder.” Design/methodology/approach An accurate adding device exogenous powder was designed control flow rate. The tribological properties and without were investigated by pin-on-disc tribometer during dry sliding. Findings Experimental results indicate that Cu addition tends increase coefficient. For pure material, exhibits poor fluidity...
