Earthquake Resistant Engineering and Application of Seismic Zonation Map of China

China is a country with high seismieity. It is very important for industry and structure to fortify against earthquakes. In this paper the outline of seismicity in China, the criteria for fortification against earthquakes and the contents of seismic zonation map of China are described. The contents of seismic safety evaluation for major construction projects, such as large dams, large bridges, long distance pipe lines for transporting oil and natural gas, nuclear plants, petrochemical enterprises and so on, are presented. Some geological disasters caused by destructive earthquake, such as earthquake-caused collapse and landslide, liquefaction of saturated soll and earthquake fault and so on, are also presented. Preventive countermeasures for these disasters are discussed.

DEGREE CONDITIONS FOR GRAPHS TO BE FRACTIONAL （a, b, n）-CRITICAL GRAPHS

Let G be a graph, and a and b be integers with a ≤ b. A graph G is called a fraetional （a, b, n）-critical graph if after any n vertices of G are deleted the remaining subgraph has a fractional [a, b]-factor. In this paper two degree conditions for graphs to be fractional （a, b, n）-eritical graphs are presented, and the degree conditions are sharp in some sense.
