However, it can only implement the limited operation to the spatial objects, cannot carry on transformation, index, interlink age and excavation to the spatial data, and hard integrate other information with combining map variable to set up and analysis new variable. Meanwhile, relational model in the traditional DBMS and the object- oriented modeling do not completely suit the spatial application domain. The relational model can handle topological relation well, but shows inabilities to that complicated level crossing the spatial region. Object-oriented model using software method based on the principle of the customer defined data type supports the abstract data type, especially spatial abstract data type, and possesses polymorphism and inheritances, and it can deal with topological and the layer relation, but hardly processes important continuous phenomenon in space.

GIS是当今操作有关空间信息的成熟工具和技术，但其只能对空间对象进行有限的操作，不能对空间数据进行变换、索引、链接和挖掘，难以集成其他信息来构建和分析新变量；而传统数据库管理模型中的关系模型和面向对象建模也不完全适合空间应用这一领域，关系模型能够较好地处理拓扑关系，但对表示横跨空间区域的复杂层次却无能为力；面向对象模型的软件方法支持抽象数据类型，特别是空间抽象数据类型，具有继承性和多态性，能够处理拓扑和层次关系，但难以处理空间中重要的连续性现象。

Previously, lithologies and sedimentary environments were commonly identified through core observation and/or comprehensive analysis of sample log data. However, the application of these methods is constrained because the core data and sample log data acquired during drilling are limited. The trend is to identify sedimentary facies through the integration of various log data.

After that the analysis used data dictionary, data flow, the system's function chart ER diagram analysis of the various systems and data.

在系统分析中先后用数据字典、数据流程、系统的功能结构图、ER图分析了系统所需的各种数据。

A heteroscedasticity regression analysis method for censored data is presented,and it extends the traditional regression analysis,which is only suitable to complete and homoscedasticity data,to censored and heteroscedastic data.

提出截尾数据异方差回归分析方法，将传统的只适用于同方差和完全数据的回归分析推广到异方差和截尾数据的情况。

The main research methods are:(1)Theory analysis:from the 2D plane geometry analysis, dots continuity characteristics are found. The first time irrational fraction algorithm is used in FM program.(2)Experiments reaearch:experiments of condition halftone function are designed under the cross-experiment principles.
