The special fine sand concretes are now in common use of constructional engineering in some areas in our country.

特细砂混凝土在我国一些地区的建筑工程中普遍使用，但是，在特细砂混凝土施工时，极易出现分层现象。

Combined with the boundary continuity condition between two kinds of two-phase medium, this finite-element method is facilitated to compute the seismic response of layered model.

文中首先推导了黏弹性双相介质的显式有限元表达式，并编制了程序；给出了黏弹性双相介质交界面的连续条件，这样就可以方便地应用于分层地质模型的计算。

It is in urgent need to build a traffic accident information spatial-database based on GIS. The contents of a perfect traffic accident information spatial-database should include three parts, i.e. spatial-database, influential factors database and database of metadata and data dictionary. Its important application value is described. The data in the database are organized with the idea of layer-organization in GIS. The structure of each table and correlation in-between these tables are designed in detail. T...

笔者分析了建立基于GIS的交通事故信息空间数据库的紧迫性；探讨了完备的交通事故信息数据库的内容构成，认为应包括空间数据库、影响因素数据库以及元数据和数据字典库三大部分；研讨了交通事故空间数据库的重要应用价值，进而采用GIS的分层组织思想对交通事故信息空间数据库中的数据进行组织；详细设计了各个数据表以及数据表间的关系，建立了包含交通事故对象、人、车、路以及环境等要素的交通事故空间数据库，为交通事故研究提供完备的数据支持。
