剖面

Referencing to the internal and external documents, we have plotted the balanced evolutions for the various typical structures by computer, which is the first time at home; applied the balancing technique by computer to the representative structures in Sichuan Oil and Gas Basin, and also established the geological modellings on three different structural elements and their own balanced evocutions in Sichuan Basin.

For the understanding of the kinetic variation and distribution of Cl in tobacco area soil of upland yellow-red earth in South Anhui ,soil samples were collected in 4 times of tobacco growth :early winter of 2002,before transplanting in next year, beginning midway, and leaf collecting .

通过对皖南旱地黄红壤烟区进行施Cl处理，施Cl后分别在初冬、次年移栽前、采烤开始、采烤中期、采烤结束后，分五次分别挖土壤剖面取土样；每次剖面层分别取0-20cm、20-40cm、40-60cm、60-80cm的土层土样，同一层同时取4-5点混匀作为一个样品，分析土壤Cl的动态变化。

Ray tracing method is used to calculate the spot pattern for different lens section plane,and then lens section plane of available dielectric material is optimized to reduce aberrations,so as to expand the field-of view.

采用射线追迹方法计算不同透镜剖面成像系统焦面上的点列图，对商用介质材料透镜通过优化剖面形状来减小像差从而获得视场扩大的效果。

Usually it does not matter whether the reflections being mapped are primary but rather whether their attitude is indicative of the attitude of the appropriate portion of the section, so that the tailing produced by the many short-path peg-leg multiples does not detract seriously.

通常，所要成图的反射波是否是一次波无关紧要，而它们的形态是否能表示剖面的部分形态却是非常重要的。所以，短程微屈多次反射波产生的拖尾对剖面质量的影响不大。

A way to construct a descriptive geometric model of a finger cutter for processing a helical gear is presented.

论述了加工渐开线斜齿圆柱齿轮指形铣刀画法几何模型的建立方法；推导出指形铣刀轴剖面廓形曲线上点的坐标方程；进行通用Autolisp程序设计，并举例绘制轴剖面廓形。

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。
