钨酸铜的生成及其氢还原过程的研究

本文提出一种生产微细钨铜复合粉的方法。将WO_3(或蓝钨)和CuO均匀混合,在空气中焙烧生成CuWO_4,再在氢气中还原,就能制得微细钨铜复合粉,其钨、铜两相分布均匀,钨颗粒细小且分布狭窄。本文详细地研究了钨酸铜的生成及其氢还原过程,与WO_3相比,发现两者的还原相变过程及动力学过程有某些差异。

Experimental Observables on Nuclear Liquid Gas Phase Transition

Progress on nuclear liquid gas phase transition （LGPT） or critical behavior has been simply reviewed and some signals of LGPT in heavy ion collisions, especially in NIMROD data, are focused. These signals include the power-law charge distribution, the largest fluctuation of the fragment observables, the nuclear Zipf law, caloric curve and critical exponent analysis etc.     

Chronobiology of sleep in humans

Periodic circadian (24-h) cycles play an important role in daily hormonal and behavioural rhythms. Usually our sleep/wake cycle, temperature and melatonin rhythms are internally synchronized with a stable phase relationship. When there is a desynchrony between the sleep/wake cycle and circadian rhythm, sleep disorders such as advanced and delayed sleep phase syndrome can arise as well as transient chronobiologic disturbances, for example from jet lag and shift work. Appropriately timed bright light is effective in re-timing the circadian rhythm and sleep pattern to a more desired time, ameliorating these disturbances. Other less potent retiming effects may also be obtained from the judicious use of melatonin and exercise.
