The Study on Modification and Application Performance of Perfluorosulfonated Acid Membrane
Perfluorinated ion exchange membrane consists of a polytetrafluoroethylene backbone and regular spaced long perfluorovinyl ether pendant side chain terminated by a sulfonate ionic group. Due to the excellent properties such as elelectrochemistry property、thermostability and chemical stability, not only used in proton exchange fuel cell but also in membrane auxiliary electrolysis technology and desalination.In this paper, [...]
Characteristics of Modern Urban Neighborhood Conservation and Spatial Form of the Green Organic Update Mode
The present days witness a great change in China cities, many of which are undertaking urban redevelopment or new town construction projects. Meanwhile, many old blocks and buildings of great historic value are vanished from the city sight. Traditional city blocks contain history information which reflects the local culture. All cities are of similar appearance, [...]

In this paper, the landscape of modern urban cemetery planning and design studies, analysis of urban cemetery planning and design of landscape elements, described to improve the city cemetery landscape planning and design of countermeasures, and lives in Wuhan Guan Shan Park Landscape Planning and Design of case study. Feng Shui and funeral culture in [...]
The Study of Traditional Residence’s Building Typology in Xinjiang Yutian
XinJiang YuTian, is located in YuMi country of the Western Han Dynasty which was intersection of east-west economic and cultures. It is a strongpoint of the Silk Road’s south path. With its unique natural geographical and cultural environments, Yutian’s culture has Characteristic complexity. Different religions and cultures mingle with each other and penetrate into the [...]
The Study of Micro Electrical Energy Storage System
The micro electrical energy can’t be stored directly, because of it’s weak electric current and voltage ,if we store it in storage battery after be amplifier by useing external energy, the energy which deplete by the circuit will be greater than the final energy which be stored in storage battery, there is no sense .This [...]
Preparation and Pervaporation of Methanol/methyl Acetate Mixture Through Zeolite -incorporated PVA/PVP Membrane
Pervaporation is a highly selective, simple and new energy-saving membrane separation tech- nology. Pervaporation can be used to separate azeotropes, close-boiling mixtures and thermally sensitive compounds which are difficult to separate by distillation and extraction. Poly(vinyl alcoh- ol) (PVA)/Poly(vinyl pyrrolidone) (PVP) blend membranes crosslinked with 4,4′-diazostilbene-2,2′-disulfonic acid disodium salt were prepared and used to separate [...]
Research on Grinding of Carbon Fiber Reinforced Plastics Used for Aviation
An important direction of new materials is to develop new techniques of composition. Carbon fiber, which has a very outstanding performance, is one of reinforcing material in advanced composite materials. Carbon fiber reinforced plastics have been widely applied in artificial satellites, high-performance aircraft and so on as one material used in aviation and aerospace. However, [...]
Determination of Forest Texture Construction Factors Based on Glcm
The remote sensing images with very high spatial resolution have rich spatial information, which is more convenient to recognize the property features of the goal objects. It is a hot point to classify and recognize the objects using the texture information during the applying research of the RS images with the high resolution. Nowadays, there [...]
Node Performance Analysis of Composite Shell Under Ocean Internal Waves
Internal waves is a kind of gravity waves which is happened to ocean layered structure (such as the density is stable stratified).And its maximum amplitude occurs in the inside of the ocean. With the same dynamics as surface waves, internal waves play an important role in the ocean.This paper firstly reference other peoples’results on constructing [...]
