According to the summary of the methods to evaluate the formation drilling resistance, the rock drillability and abrasiveness were selected to be the standards.

总结目前地层抗钻特性评价方法，选取岩石可钻性级值和岩石研磨性作为评价标准。

The figures under the abscissa are the point numbers where the stratigraphic data are taken.

a剖面904500；剖面903505。图中横坐标下的数字表示取地层料的点号，区域Ⅰ、Ⅱ为磁异常区。

It is only both heterogeneity and anisotropy of porous rock media that bring about sonically induced polarization effects in reservoirs.

正是由于地层孔隙介质中非均质性和各向异性的存在才使地层具有声激发极化效应。

A procedure to build a database by Hood's software is introduced from an example of global Cretaceous Oceanic Red Beds. It is suggested that the procession of the database is going to be executed as: new files of stratigraphic sections→taxonomic dictionary files→catalog files→running the software GraphCor-results of database and graphs of correlation + sedimentary data + geochemistry data→composite database. Some discussions on the choice of standard correlation section, first and last occurrence of a taxonomic, update and linkage of data are made.

以全球白垩纪大洋红层为例，介绍了运用GraphCor软件进行地层对比数据库建立的程序：建立剖面文件→建立化石分类单元库文件→建立目录文件→运行GraphCor软件，获得数据库和图示对比结果＋沉积、地球化学信息＋地层柱状图→综合数据库；讨论了有关对比标准参考剖面的选取、分类单元的始现和末现层位、数据库的更新及衔接等问题。

And then Finite Difference Time Domain equations and absorbing boundary condition of the cylindrical coordinates are developped.

然后在均匀地层和二层阶跃地层中计算了测井响应，与解析解符合得较好。
