Starting from the classical equation of motion for a mesoscopic capacitance coupling circuits,the quantum fluctuations of charge and current of the circuits in a displaced squeezed Fock state are investigated.It is found that the quantum fluctuations of charge and current in each component circuit depend on the device of the two loop circuits and squeezing parameters,while the fluctuation does not depend on displacement parameters.

By considering the detuning and the initial atomic coherence,a general expression of distance between density operators of arbitrary initial states (reference states) is obtained. The emphasize is put on the influence of detuning on the evolution in the interaction of a two-level atom of arbitrary initial states with the coherent field. The results show that the distance between density operators is obviously dependent on the value of detuning.

Effects of Ba filling fraction and Fe content on thermoelectric properties of Ba2+-filled p-type skutterudite compounds BayFexCo4-xSb12(x=1.0—1.6,y=0—0.63) were investigated.Effects of oxidation valence of filling atoms on electrical transport properties of filled skutterudeite compounds were also discussed.The greatest ZT value of 0.9 was obtained for Co-rich Ba0.27FeCo3Sb12.
