We analyze the random disturbance in the transmission of light through a spinning Glan-Thompsontype prism *** disturbance makes the dependence of the transmission on the rotation angle significantly deviates from the Malus cosine-squared law and severely spoils the output light *** vibration of the polarizer as it rotates combing the multi-beam-interference effect raises the disturbance. Further analysis reveals the sensitive dependence of the disturbance on the composing material of the prism gap,and the appropriate selection of such material can make the disturbance minimize to very desirable *** model results show quite good agreement with experiments.

We study the effect of a force-free end on the mechanical property of a stretched *** system can be divided into two *** first part consists of the segment counted from the fixed point（i.e.,the origin） to the forced point in the biopolymer,with arclength L_*** second part consists of the segment counted from the forced point to the force-free end with arclength △*** apply the path integral technique to find the relationship between these two *** finite temperature and without any constraint at the end,we show exactly that if we focus on the quantities related to the first part,then we can ignore the second part *** Carlo simulation confirms this *** contrast,the effect for the quantities related to the second part is dependent on what we want to observe.A force-free end has little effect on the relative extension,but it affects seriously the value of the end-to-end distance if △L is comparable to L_f.

The fluorescence of polystyrene labeled with pyrenyl groups has been investigated in concentrated solutions. The ratio of excimer to monomer intensities (I-c/I-m) of pyrenyl labels is found to vary with increasing polymer concentration (C) and display fractional dependence on the C. A critical concentration, C-m at about 0.32g/ml, is first manifested. The results are interpreted by interchain interaction and entanglement of polymer chains.

For a sample of 33 narrow-line Seyfert 1 galaxies(NLS1s)(z<0.1) from the Sloan Digital Sky Survey,we investigate their *** find that 24 NLS1s show clear bar structure and 9 NLS1s show no bar *** bar frequency in this NLS1s sample is about 70%.We do not find any difference in the location of NLS1s with or without bars on the MBH-σ* diagram.
