大别造山带上部地壳结构的有限差分层析成像

将有限差分层析反演方法用于大别造山带人工地震测深剖面上部地壳初至波的走时层析成像，得到这一剖面上部地壳横向不均匀结构图像表明，在南大别地区的超高压变质带发现榴辉岩相岩石，其下方3km深度以内的基底仍具有大陆地壳构造中正常的结晶基底速度（6．00km／s左右）；北大别地区在整个上地壳保持正常的速度，而在超高压带下方3km深度以下为6．20-630km／s的相对高速异常区，这一现象可能与超高压变质岩的含量增大有关．同时还表明，南大别和北大别之间至少在上地壳已有明显差异，它们之间的水吼一五河断裂可能是大别造山带内部的主要构造分界线．

2003年6月青岛崂山4级震群序列初步分析

从震群监测、地震影响、地震地质构造、序列特点及性质判定等方面对2003年6月青岛崂山王哥庄发生的4级震群进行了介绍及初步分析。此次地震的活动强度、频次、持续时间均为青岛历史上所罕见。地震时整个青岛市普遍有感，震中区有一定破坏，造成较大的社会影响。     

2001年昆仑山口西8.1级地震同震形变场特征的初步分析a

利用差分干涉雷达测量技术获取的宏观震中区的同震形变场，结合对地震活动性、震源机制、野外考察等资料分析，对昆仑山口西8.1级地震同震形变场特征进行了研究. 结果表明:宏观震中位于库赛湖东北侧，宏观震中区发震断层可分为两个形变中心区域，其中西段长约42 km，东段长约48 km，整个发震断层主破裂段长90 km；由干涉形变条纹分布格局可清楚地判断出发震断层的左旋走滑特征；断层两盘变形特征不同，南盘变形程度明显大于北盘；宏观震中附近最大斜距向位移量为288.4 cm，最小斜距向位移量为224.0 cm，宏观震中发震断层最大左旋水平位错为738.1 cm，最小地面左旋水平位错为551.8 cm.      

Distribution and Elimination of Lead Species in Soils Related to GAP of Chinese Medicinal Materials of Ligusticum Chuanxiong Hort

In this paper, the sequential extraction procedure was used for the selection of fractions of lead in seven stages corresponding to lead exchangeable, lead bounded to carbonates, to manganese oxides, to organic matters, to amorphous iron, and lead associated to crystallized iron, and to residuals. The vertical distributions of lead species were carried out in the soils related to good agriculture progress (GAP) of Chinese medical materials of Ligusticum chuanxiong Hort in Dujiangyan city and Wenchuan County, Sichuan Province. Based on those researches, it is found that the plant of Glycine Max (L.) Merr. has the character of lead enrichment and sorption, which is not reported in the literature. Using Glycine Max (L.) Merr. alternate planting with Ligusticum chuanxiong Hort is a valuable recommended in order to produce a high quality Chinese medical materials in order to eliminate the barrier on the beyond the lead limit for the import and export of Ligusticum chuanxiong Hort.

大坂山隧道地下水动态分析及对隧道作用评估

Base on the groundwater yield, water temperature and hydrochemistry change of the groundwater, we can analyze that the summer water content is obviously greater than winter water content where the in and-out wall rock of the Daban Mountain tunnel. The groundwater supply has the extensity and the seasonality. The groundwater content of the middle tunnel wall rock changes relatively steady, mainly supply through horizontal direction. And the total groundwater content is relatively little and steady in winter. The water pressure of the wall rock cranny is little. It has the fluent drainage system to dredge groundwater, which cannot constitute a threat to the tunnel lining. And the cold-proof sluice hole can normally work to drain water.     

长江中下游旱涝中期预报方法及其业务应用

介绍了双层多因子综合相似的长江中下游旱涝中期预报模型。该模型引入了具有明确动力学和热力学意义的地转西风动量经向输送和经向温度梯度诊断量，同时强调了西太平洋副热带高压对长江中下游夏季降水的关键作用，并考虑了对流层中、低层500hPa高度和850hPa温度的大尺度环流背景场。与过去业务应用的单层相似预报模型相比较，不仅物理意义和天气学含义明确，而且更符合对具有复杂动力和热力机制的降水预报的考虑。5年的预报试验和业务应用结果表明，该方法对长江中下游地区旱涝的中期趋势预报有较好的预报能力。
