Abstract: For the reality of the variable pressure in the oil field, an adjustable disk choke valve is introduced in this paper. The structure and working performance of the valve is described in detail, too. The field application of the valve shows that the valve has such advantages as simple structure, quickly facilitate, easy installation and cleaning, long service life, safe and reliable, all these leads to the broad application prospect of the valve.

Abstract: Based on the development status of children's carts in the market at present, we make the man-machine relations as the breakthrough point of the design to study and analyze the existing problems of children's carts. And we design a kind of carts with the functions not only can be pushed but also can be removed. It can not only realize the basic function of the carts but also can let the users achieve the purpose of parent-child interaction to increase the feeling between the parents and the children.

Abstract: A novel and saving energy rare earth lifting permanent magnetic chuck was designed based on neural network. The working principle, the neural network model of magnetic circuit design and the self-acting driving system of rare earth lifting permanent magnetic chuck were developed. Industry prototypes were manufactured, and they verified that the proposed rare earth lifting permanent magnetic chuck was feasible.

Abstract: The design of filament-wound composite Compressed Natural Gas (CNG) cylinders was reviewed, including the liner and filament-wound reinforcement part. The domestic and abroad standards are discussed here. It is of great significance to improving composite CNG cylinders safely. The focus of future research is summarized finally.

Abstract: With the continuous improvement of people's living standard,the demand of tourists about tourism product is growing.Tourism product packaging has a distinct regional and ethnic characteristics.In the packaging form, It is an important means of promoting the value of tourism products.^[1]However,Touris m packaging industry not only to bring economic benefits to society at the same time, also bring the ecological environment and resource potential crisis.In the 1980s,human sustainable development strategy are put forward.The new concept of development is put forward with the changes of The Times, the demand of social economic development.The tourism products of green ecological packaging design began to be widely concerned.The sustainable development of green ecological design is an important subject of tourism industry, packaging industry in China.In the process of the research of the tourism product packaging,We should strictly carry out the general principles of the limit excessive packaging of clear rules.Four kinds of goods packaging,such as drink wine、cakes、tea and cosmetics.The packing layer is less than three layers.Food packing layer is no more than two layers.Beverage, wine, cake packing space is not more than 55% of goods volume,cosmetics do not exceed 50%,tea does not exceed 25%, food does not exceed 25%;Other food packaging gap should be no greater than 45%,packing layer should be not more than three layers.

Abstract: Nowadays, energy crisis is becoming increasingly serious. Coal, petroleum, natural gas and other fossil energy tend to be exhausted due to the crazy exploration. In recent decades, several long lasting local wars broke out in large scale in Mideast and North Africa because of the fighting for the limited petroleum. The reusable green energy in our life like enormous wind power, solar power, etc is to become the essential energy. This article is to conduct a comparative exploration of mini wind turbine, with the purpose of finding a good way to effectively deal with the energy crisis.

Abstract: This project is mainly used in the comfort air conditioning system, replacing the conventional indoor air conditioning using fan convection cooling form, directly to the traditional air conditioning evaporator by convection heat transfer to type into the radiation heat transfer form, using modern new polymer composite material as the main body of the evaporator, the refrigerant cycle, in the mature theory of refrigeration the design of conventional air conditioning operating conditions of vapor compression on the overall setting of air conditioning design, exploration and design with the radiation air conditioning system technical requirements, the radiant cooling refrigerant system the data acquisition, development and design of intelligent controller and related problem of air conditioner indoor dew point control, thus the formation of completely based on the prototype structure of energy-saving radiation cooling technology of comfort air conditioning.

Abstract: This paper establish the function relationship between various parameters based on the study of the hydraulic pump and the dynamic characteristics. Through the establishment of transfer function is pull transform and the analysis of the characteristics of the transfer function of accumulator absorbing pressure pulsation actual effect. On the basis of further analysis, the improved method of effective volume of the accumulator, designed for fault detection and improve the system to provide a reliable basis.

Abstract: In this paper we describe the design, driving and electro-optical behavior of an electrofluidic, or electrowetting, display panel. Electrofluidic displays involve the movement of a colored oil water interface as a result of polarizing the interface between water and a hydrophobic surface under the influence of external electric field. The proposed direct-segment drive approach successfully drives the display panel based on electrofluidic. The electro-optical behavior of electrofluidic display samples are measured and analyzed. The t_on and t_off of the pixel is 16 ms and 8 ms, respectively, which demonstrates that electrofluidic display panels have the capability to show video content.

Abstract: Several factors influencing the performance of PV-integrated double-skin façade were analyzed. We used CFD numerical method to investigate the influence of width, height, outlet size and the angle of photovoltaic plate on the performance of PV channel based on the summer typical meteorological parameter. The PV-integrated double-skin façade were installed at east orientation in Shanghai. The recommended value of height and other factors were obtained. Height and the angle of photovoltaic plate were two most important factors which should be considered specially in the design of PV-integrated double-skin façade.
