La2分子结构与基态分子势能函数

用相对论有效原子实势，在密度泛函理论(DFT)和组态相关理论(QCISD)水平上优化计算了La2分子的结构．根据原子分子反应静力学原理，导出La2分子可能的电子状态和离解极限，用DFT中的B3LYP方法计算了基态X1∑g^ 势能曲线，拟合得到Murrell-Sorbie解析势能函数，并首次计算得到基态X1∑g^ 的谐振频率、热力学性质、力学与光谱数据。

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.
