摘要：
The Xiangxi gold mine was taken as an example to illustrate the application of the finite element and updated Lagrangian approach in the simulation and prediction of the quality of tailings effluents. The numerical modeling results suggest that tailings-water interaction at the early stage leads to the acidification and release of heavy metals which are responsible for the persistent pollution to the environment for 30 years. Tailings pore water can be gradually neutralized and contents of polluted species tend to decline markedly with time. The gangue dissolution and organic matter reaction can stimulate acid neutralization and decrease the diffusion rate of oxygen in tailings impoundments. The contents of pore-water species in upper tailings are significantly higher than in lower part and change severely at 6 m depth. Therefore, the hydrological zoning phenomenon in tailings impoundments accounts for geochemical zonation. This model has the potential to predict drainage quality of sulfide mine tailing impoundments.

摘要：
The paper is devoted to the study of compositions of polyharmonic mappings in simply connected domains. More precisely, we determine necessary and sufficient conditions of polyharmonic mapping $f$ such that $f\circ F$ (resp. $F\circ f$) is $l$-harmonic for any analytic function (or harmonic mapping but not analytic, or $q$-harmonic mapping but not $(q-1)$-harmonic) $F$.

Precipitation;Multiple time scale;Wavelet analysis;The Hengyang Basin
摘要：
This paper based on the monthly precipitation data of 9 surface meteorological stations in the Hengyang basin for 53 years (1960 to 2012), by using the methods of Morlet wavelet transform and Mexican hat wavelet analysis, the multi-time scales of precipitation of the Hengyang basin has analyzed. The results show that during the study period, the Hengyang basin has different time scales during the year and seasonal precipitation. The main periodic variation characteristics of quasi 24a, quasi 10a and quasi 3a time scales are existed in annual precipitation. And on the quasi 24a scale, the mutation points are 1963a, 1970a, 1977a, 1990a and 2004a. The characteristic period of spring and summer, or autumn and winter precipitation have highly similarity. And we speculate that the precipitation in the Hengyang basin tends to be less than normal in some time after 2012a.
摘要：
We demonstrate a novel and universal strategy to significantly boost electrochemical performances of conducting polymer-based flexible supercapacitors via the relatively facile electrodeposition of Mo-Ni-P compounds. The fabricated Mo-Ni-P@polyaniline (PANI)@carbon fiber cloth (CFC) sandwiched hybrid, for instance, delivers 94.6% of specific capacitance retention from 1 to 40 mA cm(-2) and 92.3% of specific capacitance retention at a high current density of 40 mA cm(-2) after 2000 cycles, much greater than 56.8% and 58.3% for the uncoated PANI@CFC with Mo-Ni-P, respectively. With increasing the numbers for repeatedly alternate coating PANI and Mo-Ni-P layer by layer, the specific capacitances rise almost linearly. Simultaneously, the capacitance retentions maintain high levels at 40 mA cm(-2) after 2000 cycles. A remarkable decrease in the charge transfer resistance and a markedly enhanced hydrophilicity with coating Mo-Ni-P on the surface of PANI@CFC can be found, which can greatly facilitate the electron and electrolyte ion transfer processes and thereby bring with it improved supercapacitive performance. Likewise, the supercapacitive performances of polypyrrole and poly(3,4-ethylenedioxythiophene) can be significantly enhanced in comparison with their Mo-Ni-P uncoated counterparts.

摘要：
In this paper, by constructing a generalized Armijo search method, a novel conjugate gradient (CG) model has been proposed to training a common three-layer backpropagation (BP) neural network. Compared with the classical gradient descent method, this algorithm efficiently accelerates the convergence speed due to the existence of the additional conjugate direction. Essentially, the optimal learning rate of each epoch is determined by the given inexact line search strategy. The presented model does not significantly increase the computational cost in dealing with real applications. Two benchmark simulations have been performed to illustrate the promising advantages of the proposed algorithm.
摘要：
In this work, we present a method for generating vector vortex beams with metasurfaces. A Jones calculation is employed to theoretically analyze the phase and polarization transformation from metasurfaces. The experimental results are shown to agree well with our theoretical calculation. Lastly, as a geometrical representation, the hybrid-order Poincaré sphere is proposed to describe the evolution of polarization state and phase of light wave propagating in metasurfaces. The hybrid-order Poincaré sphere can intuitively demonstrate the change of polarization state and. So it can also become an effective tool to provide help in designing metasurfaces.

Coefficient of Variation Method;Professional Quality;Trinity;Traditional Teaching
摘要：
In this paper, aiming at the problem that improves the professional quality of junior middle school English teachers we conducted a study, and put forward an evaluation model of junior middle school English teachers' professional quality under the background of "the trinity" based on the coefficient of variation method. Coefficient of variation method is the direct use of the indicators contained in the information obtained by calculating the weight of indicators. Is an objective method of empowerment. The results show that we need to combine "the trinity" English teaching model with traditional model in order to improve junior middle school English teachers' professional quality comprehensively. Although the former is superior to the latter on evaluation of the overall, the roles that two kinds of teaching modes play are different on improving the English teachers' professional quality. The former pays attention to improving the ability of organization and coordination and the communication ability with students, the latter pays attention to improving teachers' professional knowledge and written expression ability.

摘要：
In high-power laser system such as Petawatt lasers, the laser beam can be intense enough to result in saturation of nonlinear refraction index of medium. Based on the standard linearization method of small-scale self-focusing and the split-step Fourier numerical calculation method, we present analytical and simulative investigations on the hot-image formation in cascaded saturable nonlinear medium slabs, to disclose the effect of nonlinearity saturation on the distribution and intensity of hot images. The analytical and simulative results are found in good agreement. It is shown that, saturable nonlinearity does not change the distribution of hot images, while may greatly affect the intensity of hot images, i.e., for a given saturation light intensity, with the intensity of the incident laser beam, the intensity of hot images firstly increases monotonously and eventually reaches a saturation; for the incident laser beam of a given intensity, with the saturation light intensity lowering, the intensity of hot images decreases rapidly, even resulting in a few hot images too weak to be visible.

Geometric phase gradient;Spin Hall effect of light;Metamaterial
摘要：
The spin Hall effect (SHE) of light originates from the spin-orbit interaction, which can be explained in terms of two geometric phases: the Rytov-Vladimirskii-Berry phase and the Pancharatnam-Berry phase. Here we present a unified theoretical description of the SHE based on the two types of geometric phase gradients, and observe experimentally the SHE in structured dielectric metasurfaces induced by the PB phase. Unlike the weak real-space spin-Hall shift induced by the SRB phase occurring at interfacial reflection/refraction, the observed SHE occurs in momentum space is large enough to be measured directly.
摘要：
Non-dominated sorting multi-objective optimization algorithms can constantly lead to the population of Pareto front optimal. However, the non-dominated sorting strategy lacks high capability to explore the Pareto front in the evolutionary subsequent process. We introduce a mixed strategy game model into evolutionary algorithms in this paper. Based on this strategy, we propose a novel multi-objective evolutionary algorithm (MSG-MOEA). A player adopts a strategy against the rest of the players with a certain probability in their respective strategy space instead of some specific strategy. According to the results of the game earning, the player constantly updates this probability to maximize the interest of his own objective. Through the players' constant pursuit of the maximal interest, a kind of tension could be brought to the population, which would push forward the population to the Pareto front. The proposed approach has been used some test functions and metrics for validation which are taken from the standard multi-objective optimization evolutionary literature. The experiment results have been compared against the NSGAII algorithm, which is one of the most highly competitive EMO algorithms. Algorithm analysis and simulation results show that the proposed algorithm performs well in solving complex multi-objective optimization problems.

摘要：
Biological reduction of uranyl by Desulfovibrio desulfurican has been considered as a promising pathway for removing U(VI) from groundwater. In this paper, anaerobic batch tests were conducted to explore the effect of two ubiquitous ferric (hydr) oxides, hematite and goethite, on the bioreduction of U(VI) by D. desulfurican. When hematite or goethite (containing solidoid Fe(III) ranging from 10 to 30 mmol/L) was coexistent, U(VI) bioreduction could always be inhibited and the inhibitory effect was increased with increasing content of ferric (hydr) oxide. In the presence of a mixture of hematite and goethite with the total solidoid Fe(III) kept constant at 20 mmol/L, the inhibitory effect on U(VI) reduction by the minerals were directly correlated with the fraction of hematite. Moreover, a gradual increase in U(VI) concentration could be observed in all ferric (hydr) oxide treatments after ten days, accompanied by the release of ferrous ion into the solution. In summary, the presence of ferric (hydr) oxide can lead to the eventual incomplete U(VI) bioreduction.
