Rule-based and reusebased method is adapted in our system to develop applications. Rules are used to define geometric representation of geographic objects, spatial relationships among geographic objects and map design rules. Reusability is realized through object's inheritance and encapsulation. The basic function related to GIS has been implemented in OOGDB's basic class base. Application related function can be implemented in sub-classes of basic classes and some of basic class' function can even be overloaded.

GIS应用系统的开发采用基于规则和基于重用的方法进行，规则用于定义地理对象的几何表示和空间关系以及地图构造的规则等，重用是通过面向对象的继承和封装机制实现的，GIS实现了一个基本的类库，它完成基本的空间处理和操作，用户通过定义这些类的子类重用类库提供的功能，并增加与应用系统有关的特殊功能，用户甚至可以通过重载修改某些类库的功能。

Using the base line forces as fundamental variables, the complementary energy of an element with geometrical nonlinearity is constructed, which contains both deformation part and rotation part.

以基线力为状态变量，构造几何非线性问题单元的余能，该余能包括变形部分和转动部分。

In a digital environment where all the data sources are geometrically registered to a common geographic base, the potential for information extraction is extremely wide.

在数字环境下的所有数据源的几何注册到一个共同的地理基础，潜在的信息提取非常广。

Based on geordie coefficient, we measure the diversification of the urban system spatial polarization degree of Northeast China in different period by referring the model of polarized index which is used widely abroad or designing a new on the base of this.

以基尼系数为基础，引用国际上应用较多的或在此基础上设计新的"极化指数模型"，用以测定不同时段东北地区城镇系统的空间极化程度的变化。

In the base of population and quantity of house-completed data of Xi'an, the paper builds an Auto-regressive Distributed Lag Model of population Geordie coefficient and quantity of house-completed, and analyzes the relationship between the two, which find that house construction is one cause of population suburbanization, but contrarily it's not.

本文以西安市人口和住宅竣工量为基础数据，建立人口基尼系数和住宅竣工量之间的自回归分布滞后模型，并对二者的关系进行了分析，发现住宅建设是西安市人口郊区化的动力之一，反之则不然。

Massif form the hard base on the lower part of the ground, above which Okcheon geosyncline and Pyeongan basin, Daedong basin, and Gyeongsang basin form the sedimentary basins of the Paleozoic era and the Mesozoic era.

如果将其作为构成土地的单位加以划分，京畿陆块与小白陆块形成了下部的坚实基础，其上形成了沃川地向斜带和平安盆地、大同盆地及庆尚盆地等古生代与中生代的沉积盆地。

We are the main research and production base of Germanium and infrared optical material in China.

公司前身是北京有色金属研究总院红外材料研究所，从事半导体锗及红外材料研究四十余年，在国内一直保持领先地位，获国家和部级科研成果30多项，成为我国锗的应用和红外光学材料的主要开发、生产基地。

The soil had great population of bacteria, but the fungi quantity is excessive which may cause the multiplication of germina. As base-fertilizer, the slowed-release fatty had positive influence on soil fast-effect nutrient, but the organism quality is small, the soil enzyme activity with microorganism activity both low. Soil EC, total nitrogen, available nitrogen, available phosphorus and organic matters were significantly negative related to the soil pH. Soil total nitrogen was positive significantly related to soil available nutrient.

土壤中pH值与土壤EC值、土壤全氮、速效氮、速效磷、有机质含量呈显著负相关，土壤全氮含量与土壤速效养分含量有极显著正相关关系，而且土壤有机质含量与土壤速效养分之间也有相互促进的作用，所以土壤养分的平衡效果非常重要，有机肥处理后土壤养分全面，肥力较高。
