cellular automata (QCA)%29&ck%5B%5D=abstract&ck%5B%5D=keyword'> is a new nanotechnology for the implementation of nano-sized digital circuits. This nanotechnology is remarkable in terms of speed, area, and power consumption compared to complementary metal-oxide-semiconductor (CMOS) technology and can significantly improve the design of various logic circuits. We propose a new method for implementing a in QCA technology in this paper. The proposed method uses the intrinsic features of QCA in timing and clock phases, and therefore, the proposed cell structure is less occupied and less power-consuming than existing implementation methods. In the proposed , compared to previous best designs, reductions of 6.45% in area occupation and 44.49% in power consumption were achieved. In addition, for the first time, a reset-based and a with set and reset capabilities are designed. Using the proposed , a new 3-bit is developed which reduces 2.14% cell numbers compared to the best of previous designs. Moreover, based on the 3-bit , a 4-bit is designed, which reduces 0.51% cell numbers and 4.16% cross-section area compared to previous designs. In addition, two selective s are introduced to count from 0 to 5 and from 2 to 5. Simulations were performed using and tools in coherence vector engine mode. The proposed circuits are compared with related designs in terms of delay, cell numbers, area, and leakage power.

Steel output per unit GDP is an important index for controlling steel output, for energy-saving, materials-decreasing and wastes-reducing of steel industry. This paper first gave the definition of steel output per unit GDP, introduced the concept and calculating formula of "in-use steel", Then two times of transformation for the definition formula of steel output per unit GDP were undertaken to obtain the new definition formulas with analytic function. Steel output and energy consumption, materials consumption & wastes emission of steel industry were analyzed by using the new definition formulas of steel output per unit GDP, calculating formulas of steel output, energy consumption, materials consumption & wastes emission. Finally parameters related to steel industry were categorized and overall view for comprehensive promoting energy-saving, materials-decreasing and wastes-reducing of steel industry were put forward.

According to the features of using process, the energy use could be divided into two categories including the energy use in the field of consumption (EUFC) to provide services and the energy using in the field of production (EUFP) to provide products. The feature of EUFC is different with EUFP, including evaluation methods, energy saving approach and developing strategy, etc. Considering its potential to be the main growing sector in the next period of energy consumption, more attention should be paid to EUFC. In this paper, based on the analysis of its features, the measure of EUFC and the energy saving approach are recommended, as well as the suggestions to the present situation in China.

Strategic Study of CAE 2014, Volume 16, Issue 2, Pages 58-67
Numerical simulation and calculation were performed on the gas-phase flow field of the straight tangential cyclone with single entry，straight tangential cyclone with double entries， bias tangential cyclone with single entry，bias tangential cyclone with double entries，bias tangential helicoidal cyclone with single entry，bias tangential helicoidal cyclone with double entries by using RSM model. Results showed that，the pressure field and velocity field of the cyclone with double entries had better symmetry and stability；only changing the inlet angle had a limited influence on the pressure field and velocity field. When the tangential velocity distribution were similar in the six kinds of cyclone studied in this article，compared with other cyclones’， the pressure drop of the bias tangential helicoidal cyclone decreased about 25 %；the inlet total pressure needed was about 17 % lower；the energy consumption dropped about 17 %. Moreover，bias tangential helicoidal cyclone with double entries（XS-L type）had a better energy efficiency ratio，and its performance was the most excellent.

The state of current China building energy use is presented. It is classified into the energy for space heating in North urban buildings, energy for space heating in Yangtze River area, energy for urban residential buildings, energy for non-residential buildings as well as energy for rural residential buildings. The characters, problems and key points for saving energy for each classification above were discussed in detail. Comparison with real building energy data in developed countries was also made in order to get clear idea on current China building energy state. It shows that current China building energy use is much lower than developed countries whatever in terms of per capita or in terms of building floor area. This is mainly due to the different lifestyles and different modes of building use. It is important to maintain the thrift mode in China in order to achieve the Chinese building energy conservation target. This should be the start point to design Chinese building energy strategy. As different lifestyles and different building use modes do need different technique measures, we should develop our own approach to realize their low building energy use target rather than follow the approaches that what happened in the developed countries.

In March 2006，《The Outline of the 11th Five-Year Plan for National Economic and social Development (Profile)》stated that energy consumption per unit of GDP will be reduced by about 20% in “The 11th Five-year Plan ” period，which indicates the economic growth is transferring from conventional industrialization to new pattern. Due to the economic structure emerging with high energy intensity in “The 10th Five-year Plan”period, the proportion of energy consumption of industrial sector had gradually increased from 68.63% to about 71% of the national energy consumption. Apparently, iron and steel industry had experienced its rapid growth with the steel output increasing from 128.5 million tons to 352.39 million tons and the annual growth rate of 22.36% . Its energy consumption accounted for 21 % of the whole industrial energy consumption. Therefore, how to realize the sustainable development of increasing the output while reducing the energy consumption in those high-energy intensity enterprises would provide the good reference to the industrial sector, even to the whole country. Based on the investigation and analysis on WISCO, some important inspiration and experiences were summarized.

An international comparative analysis aimed at perspectives on China's energy development scope is presented in this paper. By comparing the development course of the energy consumption of the United States, Canada, Europe and Japan, we find that although these countries have achieved the same level of development, they have made major differences in per capita energy consumption. Based on this, we propose the concept of "two types of developed countries", which we describe as "America and Canada model" and "Europe and Japan model "(the latter can be further broken into the "Europe model" and the "Japan model"). The reasons for the consumption differences of the different models are analyzed separately in industry, transport, residential, commercial and public services end-use sectors. In conclusion, based on the comparative analysis of those developed countries and China's actual conditions, the paper proposes that China's growth scope of per capita energy consumption is less than her per capita energy consumption in 2010, and several suggestions for the energy development are given.
