In order to promote the intelligent transformation and upgrading of the steel industry, intelligent technology features based on the current situation and challenges of the steel industry are discussed in this paper. Based on both domestic and global research, functional analysis, reasonable positioning, and process optimization of each aspect of steel making are expounded. The current state of molten steel quality and implementation under narrow window control is analyzed. A method for maintaining stability in the narrow window control technology of steel quality is proposed, controlled by factors including composition, temperature, time, cleanliness, and consumption(raw material). Important guidance is provided for the future development of a green and intelligent steel manufacturing process.

Reproduction of focused sound sources is a fundamental problem in acoustic signal processing. Based on the cylindrical harmonic expansion of higher order Ambisonics(HOA), a novel method for focused sound source reproduction is proposed. To restrict the near-field distortion caused by higher order harmonic components of focused sound sources, a Symmetry sigmoid regularization function(SSRF) is designed, which exhibits a more suitable attenuation characteristic. By using SSRF, we first give the generalized cylindrical harmonic expansion of focused sound sources. The concept of continuous loudspeaker is utilized over a circular array to generate the discrete loudspeaker driving function. Based on the wideband error analysis, the match relationship between the SSRF and the variance pair(i.e., the operating frequency and the expansion order) is established. Objective evaluation results show that the near-field distortion is eliminated significantly by the proposed method. The reproduction errors of interior/exterior sound field are evidently lower than the state-of-the-art techniques. The subjective evaluations also confirm that the proposed approach is able to achieve higher reproduction quality compared to the referenced methods.

As a basic factor in the environment of estuary, tidal effects in the coastal aquifer have recently attracted much attention because tidal dynamic also greatly influences the solute transport in the coastal aquifer. Previous studies on tidal dynamic of coastal aquifers have focused on the inland propagation of oceanic tides in the cross-shore direction, a configuration that is essentially one-dimensional. Two-dimensional analytical solutions for groundwater level fluctuation in recent papers are localized in presenting the effect of both oceanic tides and estuarine tides in quadrantal aquifer. A two-dimensional model of groundwater fluctuations in estuarine zone in proposed in this paper. Using complex transform, the two-dimensional flow equation subject to periodic boundary condition is changed into time-independent elliptic problem. Based on Green function method, an analytical solution for groundwater fluctuations in fan-shaped aquifer is derived. The response to of groundwater tidal loading in an estuary and ocean is discussed. The result show that its more extensive application than recent studies.

BACKGROUND： The benefits of the application of basiliximab induction therapy in liver transplantation are not clear. The present meta-analysis was to evaluate the pros and cons of basiliximab use in liver transplantation. DATA SOURCES： We searched the associated publications in English from July 1998 to December 2015 in the following databases： MEDlinE, Pub Med, Ovid, EMBASE, Web of Science and Cochrane ***： Basiliximab significantly decreased the incidence of de novo diabetes mellitus after liver transplantation（RR=0.56; 95% CI： 0.34-0.91; P=0.02）. Subgroup analysis showed that basiliximab in combination with steroids-free immunosuppressant significantly decreased the incidence of biopsy-proven acute rejection（RR=0.62; 95% CI： 0.39-0.97; P=0.04） and new-onset hypertension（RR=0.62; 95% CI： 0.42-0.93; P=0.02）.CONCLUSIONS： Basiliximab may be effective in reducing de novo diabetes mellitus. What is more, basiliximab in combination with steroids-free immunosuppressant shows statistical benefit to reduce biopsy-proven acute rejection and de novo hypertension.
