To find environment-friendly and low pest resistance natural mosquitocide, The insecticidal activity of the essential oil extracted from fructification ofIllicium verumagainstAedes albopictusandCulex pipiens quinquefasciatuswere investigated. The compositions of this oil was analyzed by GC-MS. The results are given as follows, The 24-h LC50values ofIllicium verumessential oil for I, II, III, IV-instar larvae and pupa ofAedes albopictus/Culex pipiens quinquefasciatuswere 4.93/2.04, 8.36/2.96, 11.88/8.42, 16.10/13.13 and 42.31/75.12 μg·mL-1, respectively. A total of 18 compounds identified fromIllicium verumoil, the major volatile components were trans-anethole with the peak area percentage of 94.8%, followed by 1-(3-methyl-2-butenoxy)-4- (1-propenyl) benzene (3.2%), estragole (0.4%), linalool (0.3%) and limonene (0.3%). The results indicates thatIllicium verumoil can be developed into a botanical mosquitocide.

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.
