Currently, there are so many heavy vehicles being driven fast and overloading on highway. Carrying capacity of highway are not fit with this situation, They are often run in a serious state of overloading and fatigue. This directly influenced the life of highway. So, to improve the mechanical properties and carrying capacity of highway, and to construction high standard, high speed, large-tonnage, long-life modern highway are urgent and imperative. This article analyzes the current traffic load and design, materials select and construction status of highway, and proposed some measures to improve mechanical properties and construction standards of highway. Life of highway can be greatly improved by adopt these measures. © (2011) Trans Tech Publications.

With the more and more serious energy and environmental problems, reducing the consumption of resource came to the urgent affair at present. Energy-saving composite wall was an effective measure to reduce the energy consumption of building. This paper deals with the features, application and seismic performance of sandwich composite concrete block wall, the purpose of which is to provide a scientific basis for the seismic performance designing of the concrete block composite wall with the characteristic of load-bearing, warm-keeping and decoration. © 2011 IEEE.

Variations in the solar wind dynamic pressure can create changes in the auroral brightness, especially in the dayside region. In this study, mainly using Polar Ultraviolet Imager auroral images and NASA OMNI magnetic field and plasma data, we investigate the relationship between interplanetary parameters and dayside aurora intensification. We first identify the dayside aurora cases caused by the solar wind dynamic pressure increases from 1997 through 1999 and divide these cases into two types: one with intensification and the other without significant intensification following the increase in the solar wind dynamic pressure. Then, case by case, we examine the separate roles of the solar wind density and velocity on auroral brightness. Our result demonstrates that the dayside aurora intensification requires the contributions of both the density and solar wind velocity increases. The solar wind density increase alone (without velocity increase) could not create the dayside aurora intensification. Copyright © 2011 by the American Geophysical Union.
