Na_2O,MgO,Al_2O_3,SiO_2,P_2O_5,SO_3,K_2O,CaO,TiO_2,MnO and Fe_2O_3 in cement and cement clinker were determined by wavelength dispersive x-ray fluorescence spectrometer.
It is found that the chromatic dispersion of the Coude system is almost flat.Dispersions in grade 1-3 are 8.391±0.09/mm(m=1),4.185±0.05/mm(m=2) and 2.794±0.03/mm(m=3) respectively.
In this paper, the numerical approximation by Galerkin method for completely compressible miscible displacement with molecular diffusion and dispersion in porous media is considered.
We present a simple proof of the resolvent estimates of elliptic Fourier multipliers on the Euclidean space, and apply them to the analysis of time-global and spatially-local smoothing estimates of a class of dispersive equations.
We introduce the concept of "breathing" solitons to describe the dynamics of optical pulses in transmission lines with passive compensation of fiber chromatic dispersion.
A new method for calculating the radiation loss and chromatic dispersion of leaky modes propagating in microstructured (holey) optical fibers (MOFs) with circular air-filled channels is proposed and implemented numerically.
The influences of the dispersion reagent, the alkalinity and the calcination temperature on the surface morphology of nanopowders, and the electric conductivity were discussed.
Moreover, it was shown that the dispersion ability of CNT in aqueous solution had a significantly improvement after CNT functionalized with NB even at a level of high concentration, for example, 5 mg of NB-CNT per 1 mL of H2O.
The main results are illustrated by applying the proposed test to type II censored data from the exponential distribution and to the test problem for the dispersion parameter in the linear regression model.
Based on the relation of time-frequency distribution of the acoustic leak signal and the dispersion curves of guided waves, the mode components of acoustic leak signals were obtained.
The factors that influence the dispersion property of ultrafine α-Al2O3 powder are discussed in this paper, such as the methods of adding materials, surfactant, and drying methods.
