The depth profiles of Ni-coated copper substrates polished by different mesh size sandpapers were measured by the glow discharge optical emission spectroscopy (GDOES) depth profiling technique. The measured depth profiles were well fitted by the MRI-CRAS model developed recently on the basis of the Mixing-Roughness-Information depth (MRI) model and the CRAter-Simulation (CRAS) model, taking into account the pronounced crater effect upon GDOES depth profiling. The crater effect upon depth profiling was characterized quantitatively and the interface roughness values between the coated Ni layer and the Cu substrates were determined and compared with the ones measured by AFM.

This paper considers single machine scheduling with general position-dependent and job-dependent aging effect. All jobs share a common due window, and an optional maintenance activity (OMA) is taken into consideration. The processing time of a job is a non-decreasing function in its position. Such category of maintenance activity is called the OMA since one can determine the position and the actual duration of it. The objective is to determine the optimal due window position, the optimal location and duration of the OMA, and the optimal job sequence so as to minimize the total of earliness, tardiness, due window starting time, due window size, and the OMA duration related costs. We show that the considered problem can be solved in polynomial time.

Through the work of measuring magnetic susceptibility of the cores in Yinmin mining area, Yunnan, one can draw a conclusion that different strata have different magnetic susceptibility, and variations of magentic susceptibility as a whole have significant changes, concerned primarily with mafic ferruginous lava, iron ore, ferruginous dolomite and fine grained diabase in the Luoxue Group and the Yinmin Group. The study of magnetic susceptibility of the rocks is not only relevant to magnetic prospecting and the boreholetricomponent magnetic, but also a rapid and effective means of geological exploration for the iron-oxide copper gold (IOCG) deposit in Yinmin mining area.

The 28 cities in the upper, middle and lower reaches of the Yangtze River can be regarded as an epitome of the cities in eastern, central and western China. Therefore, the low-carbon development level of the cities along the Yangtze River objectively reflects the overall development degree and regional difference of Chinese low-carbon cities. On the basis of analyzing and understanding the connotation of low-carbon cities, this thesis sets up the appraisal index system of low-carbon cities, puts forward the concept of low-carbon index, and conducts a cluster analysis and appraisal to the low-carbon indexes of 28 cities along the Yangtze River through a spatio-temporal path.

According to the primary study on the As contamination in soil and crops including potato and pea in tin tailings in Gejiu area, Yunnan Province, it has been found that concentrations of As in rhizosphere far exceed Chinese National Grade Ⅲ standard of soil environmental quality of China (GB 15618-1995). It also has been found that the Ferns were living in the tin tailings suffered from the contamination of heavy metals. Compared with the limit of national criteria for food sanitation in China, the concentrations of As in edible parts of ferns are 90 times. Therefore, the remediation of soil based on geochemical distribution characteristics of heavy metal in the tailings is demanded. And avoiding crops-planting in the tailings to reduce the diffusion of heavy metal contamination in food chain of mining area is necessary.

Investigations on macronutrients (K, Na, Ca, Mg and P) and micronutrients (Fe) in windy sand- and salt-resistant plant species such as Cymomorium can help us to get a better understand their behaviours of ecologically environment geochemistry in the Gobi arid desert ecosystem. This study presents our investigations on the concentrations of K, Na Ca, Mg, Fe and P in xerophilous, sabulicolous, superhalophilous Cymomorium from the oasis ecosystem in the Beishan-Tianshan Gobi arid desert, northwestern China. The mean concentrations of macronutrients (K, Na, Ca, Mg and P) in Cymomorium Songaricum Rupr. are, respectively, 1.29±0.29 % K, 2.45±1.08 % Na, 2966±2038 μg g–1 Ca, 2038±1746 μg g–1 Mg and 1462±457 μg g–1 P. Although the average concentrations of Fe concentrations (341±361 μg g–1) is within the normal range of Fe in plant species, the maximum Fe concentrations (1400 μg g-1) were detected in Cymomorium stemmed from the sandy lowland around the Shaquanzi iron mine of the Xinjiang Uygur Autonomous Region in China. It suggested that the indigenous species of Cymomorium might be one of the appropriate xerohalophyte species to restore the vegetation of the oasis, saline land use for agriculture or arid environments destroyed by mining activities in the dry land because it may have higher ability to accumulate K, Na, Ca, Mg, Fe and P from saline soils, and it belongs to the native salt-resistant plant species.

Numerical simulations have been captured for 3-D crossing shock wave/turbulent boundary layer interactions generated by 15-deg sharp fins mounted symmetrically on a flat plate at mach8.3. The full Reynolds-averaged Navier-Stokes equations are solved with high-resolution implicit finite-volume scheme. Turbulence closure is achieved with Spalart-Allmaras(SA), Wilcox’ k-ω and Menter’s Shear Stress Transport (SST) models. Complex crossing shock wave interactions, flowfield structures including the boundary-layer separation, centerline vortex, vortex interaction and entrainment flow have been revealed. Comparisons for profiles of the velocity vector, pressure and heat transfer distribution have been observed between calculated results and experimental measurements. Behavior of turbulence models in the complex flow have been pointed out. SST shows better performance in calculating the pressure and the velocity vector and all turbulence models over-predicted heat transfer coefficient.

The paper studies on the geochemical characteristics of major element, trace element and REE of granite, marble and skarn in Xinshan Area in Kafang. The studies have shown that the granite in Xinshan Area is high-potassium calc-alkalic granite. The distribution plots of REE in different lithological rocks have obvious differences, but all three different lithological rocks have the characteristic of LREE enrichment. The ratio of LREE to HREE of Marble and skarn is larger, while that ratio of granite is smaller. The variation of LREE and HREE of Skarn is large, indicating that REE occurs significantly different in the migration process and the extent of wall rock material exchange.

Ionic liquid containing L-alanine cations and hydrogen sulfate was synthesized using L-alanine and sulfuric acid as materials. Fourier Transform Infrared Specctrometer was used to verify the final product. The results showed that the objective product was developed successfully. General properties of the final product were detected. The results showed that strong acidity, large viscosity, soluble in polar solvents and insoluble in nonpolar solvents were the product’s properties which were suitable for liquefying. The liquefaction rate of ionic liquid on paper was studied. Study the optimum liquefaction condition using the method of orthogonal experiment design. By stirring at 80°C for 3 hours using ionic liquid with the concentration of 100%, liquefaction rate of ionic liquid on paper was high.

With the rapid economic development in China, the domestic copper demand grows sustainedly and drives the continual expansion of China copper industry.

Combined the experienced data of early developed industrial countries to our practical situation, the growth trend and development limitation of China copper industry lifecycle are analyzed by the growth curve model, which is significant for the accord development of China copper industry.

Aiming at the problem of traditional iterative way to achieve method of multi-step prediction, new method of multi-step prediction based on parallel Support Vector Regression (SVR) was proposed. To begin with the time delay of time series will be calculated in this method, resample the time series according to the interval of time delay. What’s more the time series will be classified into several sets of data, and it sets up SVR model for the sets of each. Finally, the parallel prediction of each set is composed to get multi-step prediction result. This method not only eliminates the accumulated error, improves the accuracy of prediction, but also saves the computation time.
