	1	A numerical study for off-centered stagnation flow towards a rotating disc显示文摘In this investigation,a semi-numerical method based on Bernstein polynomials for solving off-centered stagnation flow towards a rotating disc is introduced.This method expands the desired solutions in terms of a set of Bernstein polynomials over a closed interval and then makes use of the tau method to determine the expansion coefficients to construct approximate solutions.This method can satisfy boundary conditions at infinity.The properties of Bernstein polynomials are presented and are utilized to reduce the solution of governing nonlinear equations and their associated boundary conditions to the solution of algebraic equations.Graphical results are presented to investigate the influence of the rotation ratioαon the radial velocity,azimuthal velocity and the induced velocities.A comparative study with the previous results of viscous fluid flow in the literature is made.

	2	A glance on the effects of temperature on axisymmetric dynamic behavior of multiwall carbon nanotubes显示文摘In this paper the effects of temperature on theradial breathing modes(RBMs) and radial wave propagation in multiwall carbon nanotubes(MWCNTs) are investigated using a continuum model of multiple elastic isotropicshells.The van der Waals forces between tubes are simulatedas a nonlinear function of interlayer spacing of MWCNTs.The governing equations are solved using a finite elementmethod.A wide range of innermost radius-to-thickness ratioof MWCNTs is considered to enhance the investigation.Thepresented solution is verified by comparing the results withthose reported in the literature.The effects of temperature onthe van der Waals interaction coefficient between layers ofMWCNTs are examined.It is found that the variation of thevan der Waals interaction coefficient at high temperature issensible.Subsequently,variations of RBM frequencies andradial wave propagation in MWCNTs with temperatures upto 1 600 K are illustrated.It is shown that the thick MWCNTs are more sensible to temperature than the thin ones.

	3	Piezoelectric Study of 0.65Pb(Mg_(1/3),Nb_(2/3))O_3-0.35PTO_3 Nanopoder Ceramics显示文摘The piezoelectric properties of relaxor ferroelectric 0.65Pb(Mg1/3Nb2/3)O3-0.35PbTiO3 ceramic prepared by a sol-gel combustion method have been investigated as function of sintering temperature.The results show that its phase structure is near the morphoteropic phase boundary(MPB),and outstanding electrical properties are obtained with this composition.The highest piezoelectric coefficients were observed for the samples sintered at temperature of 1200oC.In comparison with pure PMN((1-x)Pb(Mg1/3Nb2/3)O3-(x)PbTiO3),the substitution of 35% PT results in the decrease of sintered temperature and improved the relaxation behavior.
