It is the first systematic research in the world on the composition design of epoxy asphalt concrete as pav- ing material. Material characteristics and service perform- ance of mixture, fatigue resistance characteristics of epoxy asphalt concrete by the fatigue test of complex beam have also been described. This research indicates that epoxy as-phalt concrete is a good type of paving material. Research results have been applied successfully in the paving of steel deck of the Second Nanjing yangtze River Bridge (SNYRB). It provides a new paving type for long-span steel bridges of china and has a bright application prospect.

以***的构造样式(structuralstyles)分类方案为基础,对研究区构造样式作了详细分类研究,探讨了不同构造样式中可能出现的天然气圈闭类型。根据基底是否卷入,将构造样式分为基底卷入型和盖层滑脱型两大类,并进一步根据不同的应力环境、不同的构造组合形式划分出9种基本构造样式。构造样式的发育主要受断陷期近南北向压扭应力场的控制,晚期北西-南东向挤压应力场只起次要控制作用。每一种构造样式对深层天然气聚集都有不同程度的控制作用,其中,低角度控陷边界正断层控制的箕状断凹与断垒组合、同沉积型挤压背斜、逆冲褶皱组合、断弯背斜及其上覆同沉积背斜组合等样式中发育的背斜、断背斜型圈闭,最有利于松辽盆地北部徐家围子地区天然气的聚集。

Acta Oceanologica Sinica 2009年第3期28卷 11-16页

作者： SHAN Feng QIAO Fangli XIA Changshui college of Physical and Environmental Oceanography Ocean University of China Qingdao Qingdao 266003 China First Institute of Oceanography State Oceanic Administration Qingdao 266061 China

Observations show that during summer especially in August, the northward expansion of the Changjiang（yangtze） River diluted water （CRDW） is blocked in the vicinity of the Changjiang Estuary. To explain this phenomenon, Princeton ocean model （POM） is applied to simulate the summertime expansion pattern of CRDW. Numerical experiments show that to the north of the Changjiang Estuary, a tide-induced temperature front of a cold water centered at （34°N, I22.5°E） plays the key role in determining the expansion pattern of CRDW. This front splits the CRDW into two parts： the main part expands northeastward, and the other small part expands northwestward off the coast of Jiangsu Province, china.
