This article discusses the application of the data envelopment analysis in the energy efficiency measure of the industries, which thinks that according to energy consumption intensity industries can be divided into three categories, high, middle and low energy consumption, respectively discussion will have more theoretical significance. Later, this paper chooses constant returns to scale model, respectively measures total factor energy efficiency to three kinds of Inner Mongolia industrial industries, and summarizes the changes and characteristics of energy efficiency in these three kinds of industries. Result shows that, the energy efficiencies among high energy consumption industries are similar and recently they began to decline; the energy efficiencies of middle energy consumption industries are relatively high, but there are some differences between industries; in most low energy consumption industries energy efficiencies are low and the fluctuation is lesser, but several fluctuations are bigger which industries are worth our attention.

At present, small and medium-sized enterprises have played an important role in China's economic development. Starting with the introduction of modern industrial engineering, this paper firstly pointed out the problems of small and medium enterprises in the development process, analyzed the need for the implementation of industrial engineering, and finally proposed the application patterns and development trends of industrial engineering in Small and medium-sized enterprise management.

This paper examined the relationship between the energy efficiency and the environmental pollution. By using the data of energy intensity and economic loss caused by environmental pollution (ELP) in China from 1989-2009, a simultaneous equations was developed. The result of two-stage OLS estimation suggested that the energy had exerted positive influences on the decreasing of the environmental pollutions. By enhancing the energy efficiency and adjusting the industrial structure and energy consumption structure, China is exploring a road for sustainable development in the energy conservation.

Resource-based city has many characteristics of urban sustainable development, but because of resource's gradual depletion, population explosion and the depravation of natural ecological environment, it is more special in the road of sustainable development. The sustainable development of resource-based city has more urgency, complexity and difficulty, so traditional linear model of economic development has been unable to realize its sustainable development. Building on circular economy characterized by closing material cycle, to achieve the harmony of human and nature, the economic development and environment protection win-win strategy goal is an inevitable trend.

The microwave magnetic dynamic properties of the [NiFe(40nm)/IrMn(15nm)]6/[NiFe(30nm)/IrMn(15nm)]7/[NiFe(20nm)/IrMn(15nm)]10 multi-stacks structure films, prepared by high vacuum DC magnetron sputtering deposition, have been investigated at the frequency range from 10 MHz to 6 GHz. By changing the thickness of the ferromagnetic (FM) NiFe layer in bottom [NiFe(t nm)/IrMn(15nm)]6 stack part, a tunable lower frequency range used magnetic multilayer can be realized. The influence of the NiFe layer thickness in bottom stack to static and dynamic magnetic properties were obtained and analyzed. Combining with the top [NiFe(30nm)/IrMn(15nm)]7/[NiFe(20nm)/IrMn(15nm)]10 two stacks used in the higher frequency, a kind of multi-stacks structure magnetic thin films were fabricated for the wideband microwave noise filter.

A series of FeCoHfO granular films were fabricated by reactive DC magnetron reactive sputtering at varying partial pressure of oxygen and annealed by magnetic field thermal annealing. By using magnetic field annealing method suitably, the soft magnetic properties of FeCoHfO granular thin films are improved obviously. The optimal annealing temperature and annealing time are 350 °C and 20 minute, respectively. The films with desired properties of low coercivity, Hc~2Oe, relatively high saturation magnetization, 4pMs~20.5 kG, high anisotropy field Hk~50Oe, and high electrical resistivity r ~ 1875mWcm and natural ferromagnetic resonant frequency about 3 GHz have been obtained.

The local structure and the spin Hamiltonian parameters g factors gi (i =x, y and z) and the hyperfine structure constants Ai for Co2+ in orthorhombic CaTiO3 are theoretically investigated from diagonalization of 6 × 6 energy matrix within the 4T1 ground state for a 3d7 ion in orthorhombic symmetry. In the calculations, the contributions from the admixtures of various J states (J=1/2, 3/2, 5/2), the ligand orbitals and spin-orbit coupling and the fourth-order orthorhombic field parameter, which were usually neglected in the previous works, are taken into account. The crystal-field parameters are determined from the superposition model in consideration of the suitable lattice distortion due to the charge and size mismatching substitution of Ti4+ by Co2+. Based on the studies, the bond lengths R1 and R2 in the xy plane are estimated to suffer the relative alternation R ≈ 5.4%, yielding more significant orthorhombic distortion in the impurity center as compared with that for the host Ti4+ site in pure crystal. The calculation results based on the above local lattice distortion show reasonable agreement with the observed values. The various contributions to the spin Hamiltonian parameters are discussed. Present studies may theoretically verify that the impurity Co2+ occupies the 6-fold coordinated Ti4+ site rather than the 12-fold coordinated Ca2+ site, associated with the enhanced orthorhombic distortion due to the mismatching substitution.

The axial displacements for Co2+ and Ni3+ in Al2O3 are theoretically investigated starting from the perturbation formulas of the EPR parameters for a 3d7 ion with high spin (S=3/2) and low spin (S=1/2) in trigonal symmetry, respectively. Based upon these studies, the Co2+ is found to shift towards the center of the oxygen octahedron by an amount ZCo (≈ 0.03 Å) along the C3 axis, while the Ni3+ may suffer another axial displacement ZNi (≈ −0.38 Å) away from the center of the octahedron. The calculated EPR parameters based upon the above axial displacements show good agreement with the observed values. The differences in the EPR parameters and the axial displacements for the two 3d7 ions are discussed.
