Theoretical and Experimental Research of a New Type Automatic Wind Catcher and Ventilation System
Natural ventilation as a passive method of ventilation to save energy and improve indoor air quality has become increasingly significant advantages.Most buildings achieve natural ventilation by opening the doors and windows,and this is one of the most simple and effective means of natural ventilation.There are many specific factors limit the opening of the doors and [...]
Statistics Analysis on Mechanical Properties of Auto Aluminum Alloy Wheel Spoke
The beginning phase in the auto wheel hub production is process and mold design, but the main problem in the design cycle is long, labor-intensive, especially cannot carry on the precise computation in the design stage. It is difficult to achieve the optimal design. In this paper, the main factors that influencing the mechanical properties [...]

With the national economic development, reinforced concrete structure are serviced more and more in all kinds of projects. To concretes, they are shorts in tensile strength and other special properties. They are developmented in higher performance, and greater span and more advanced design means and construction technology and the variety development and application of new [...]
Preparation and Selective Laser Sintering of Carbon Fibre/polyamide 12 Composite Powders
Selective Laser Sintering is one of the Solid Freeform Fabrication technologies, which sinters powder materials into 3D solid components. One of the most important branches of SLS application is to directly fabricate plastic structural components by polymer and polymer-matrix composite powders, and it has a promising market. However, to meet further requirements of high dimensional [...]
Study on Performance of Cold Recycling Mixture with Emulsified Asphalt
The asphalt pavement constructed in early China is entering into maintenance period, which produces a large amount of reclaimed asphalt pavement. The technology of asphalt pavement cold recycling, which can reuse the old asphalt mixture, raise resource utilization ratio and protect ecological environment, accords with the strategic policy of developing recycle economy and realizing sustainable [...]
