The kinetic model for desulfurization using CaO-based powder injection has been proposed, which accords with the actual process of the experiment. For the model, a comparison between CaO-based flux and Mg-based flux was made and the results show that the desulfurization rate of the Mg-based flux is far more than that of CaO-based flux. On the basis of the model calculation, on comparison of CaO-CaF2 flux and calcium aluminate flux, the desulfurization rates of the two fluxes are close to each other. In addition, the effects of some operational factors on the kinetics of desulfurization are discussed.

We propose a cross-subcarrier precoder design(CSPD) for massive multiple-input multiple-output(MIMO) orthogonal frequency.division multiplexing(OFDM) downlink. This work aims to significantly.improve the channel estimation and signal detection performance by.enhancing the smoothness of the frequency.domain effective channel. This is accomplished by.designing a few vectors known as the transform domain precoding vectors(TDPVs), which are then transformed into the frequency.domain to generate the precoders for a set of subcarriers. To combat the effect of channel aging, the TDPVs are optimized under imperfect channel state information(CSI). The optimal precoder structure is derived by.maximizing an upper bound of the ergodic weighted sum-rate(WSR) and utilizing the a posteriori beam-based statistical channel model(BSCM). To avoid the large-dimensional matrix inversion, we propose an algorithm with sy.plectic optimization. Simulation results indicate that the proposed cross-subcarrier precoder design significantly.outperforms conventional methods.

The behavior of transversal cracks on the surface of the slab corner during vertical and horizontal （V-H） rolling process with flat vertical roll and groove vertical roll was simulated by.explicit dy.amic finite element method. The closure and growth of crack and the contact pressure on surfaces of the crack in contacting zone between slab and roll during rolling process were analy.ed. The results showed that during vertical rolling process, when the groove vertical roll is used, the maximum contact pressure on surfaces of the crack is 115 MPa, and the closure of crack is stable when the flat vertical roll is used, the maximum contact pressure on surfaces of the crack is 70 MPa, and it fluctuates greatly. During horizontal rolling process, when groove vertical roll is used, the contact pressure becomes zero which may.accelerate the growth of crack when flat vertical roll is used, there is still contact pressure. The cal culated results are in good agreement with the results of test.
