A Ni（Ⅱ） complex [Ni（bdpm）2（OAc）]2（N3）2.5H20 （bdpm = bis（3,5-dimethylpyrazol-1-yl）-methane） was synthesized and characterized by elemental analysis, 1R and single-crystal X-ray diffraction. It crystallizes in the monoclinic system, space group P21/c with a = 18.630（2）, b = 16.6624（19）, c = 19.821（2） A, fl = 90.146（2）°, V = 6152.9（12） A3, Z = 4, C48H80N22Ni2O9, Mr = 1226.76, Dc = 1.324 g/cm^3, F（000） = 2600 and μ = 0.680 mm^-1. The structure was refined to the final R = 0.0578 and wR = 0.1337 for 10848 independent reflections （Rint = 0.0311） and 6915 observed reflections （1 〉 2σ（I））. The complex contains two asymmetric molecules in the cell with small difference in bond distances and bond angles. Each Ni（Ⅱ） ion is bound by four nitrogen atoms of two chelating bdpm groups in a six-membered boat conformation and two oxygen atoms from one chelating bidentate acetate group to form a distorted octahedral geometry. The complex also contains azide anion outside acting as counteranion and two crystalline water molecules to link two discrete mononuclear cations though hydrogen bonds.

发展农业适度规模经营是中国式农业农村现代化的必由之路,而承包地细碎化治理是发展农业适度规模经营中的关键一环。承包地细碎化治理模式中,“承包权不动,经营权连片”在法律上的技术路径是三权分置之下的土地经营权流转;“承包权互换,承包地连片”在法律上的技术路径是两权分离之下的土地承包经营权互换。农村集体经济组织在承包地细碎化治理中发挥着统筹协调、组织服务等功能,按照法定的程序形成集体意志,还可以充当承包农户在土地经营权外部流转时的代理人,以破除集体行动困境。承包地的调整仅限于个别农户之间,并在符合法定条件的前提之下按照法定程序进行,不得以承包地细碎化治理为由扩大承包地调整的适用范围而进行“打乱重分”。

Cadmium sorption behavior of granular activated carbon oxidized with nitric acid was systematically studied by sets of the equilibrium and time-based experiments under various conditions. The cadmium adsorption capacity of oxidized granular activated carbon enlarged with an increase in pH, and reduced with an increase in ionic strength. Experimental data were evaluated to find out kinetic characteristics. Adsorption processes were found to follow pseudo-second order rate equation. Adsorption isotherms correlate well with the Langmuir isotherm model and the maximum sorption capacity of cadmium evaluated is 51.02 μmol/g. Thermodynamic parameters were calculated based on Van＇t Hoff equation. Equilibrium constant Kd was evaluated from Freundlich isotherm model constants, Langmuir isotherm model constants, and isotherms, respectively. The average change of standard adsorption heat ΔH^0 was -25.29 kJ/mol. Negative ΔH^0 and ΔG^0 values indicate the adsorption process for cadmium onto the studied activated carbon is exothermic and spontaneous. The standard entropy ΔS^0 was also negative, which suggests a decrease in the freedom of the system.

Current research shows that the traditional shock control bump（SCB） can weaken the intensity of shock and better the transonic buffet performance. The author finds that when SCB is placed downstream of the shock, it can decrease the adverse pressure gradient. This may prevent the shock foot separation bubble to merge with the trailing edge separation and finally improve the buffet performance. Based on RAE2822 airfoil, two types of SCB are designed according to the two different mechanisms. By using Reynolds-averaged Navier-Stokes（RANS） and unsteady Reynolds-averaged Navier-Stokes（URANS） methods to analyze the properties of RAE2822 airfoil with and without SCB, the results show that the downstream SCB can better the buffet performance under a wide range of freestream Mach number and the steady aerodynamics characteristic is similar to that of RAE2822 airfoil. The traditional SCB can only weaken the intensity of the shock under the design condition. Under the off-design conditions, the SCB does not do much to or even worsen the buffet performance. Indeed, the use of backward bump can flatten the leeward side of the airfoil, and this is similar to the mechanism that supercritical airfoil can weaken the recompression of shock wave.

ZK2000 is a newly developed 2 MW all radial gas turbine with an annular combustor. In this paper, the authors present the atmospheric test results of the combustor on test rig. Evaluation of several RANS turbulence models and reaction models were used in order to determine which model was the most appropriate combination for comparison with the test results. FGM with SST were selected because of the better agreement with test results in terms of combustor temperature rise, primary zone temperature, liner metal temperature, and NO_x emission predictions.
