This paper presents an approach to 2-D geometric map building and uncertainty representation under completely unknown structured environment.

本文主要研究完全未知结构化环境下的移动机器人二维几何地图构建及其不确定性描述问题。

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。

The position of the radar beam center is calculated in the three-dimensional geometry of spheres.

在星载SAR卫星地面覆盖图仿真软件方面，选择了合适的地球模型、卫星轨道模型以及地图投影法，并对波束中心位置的计算进行了推导。

Produced the gradient wind equation and showed examples of gradient wind (and its difference from the geostrophic wind) in 500mb height maps.

推导出梯度风方程并在500毫八高度地图中举出梯度风的例子（以及它与地转风的不同之处）。

Produced the height-gradient form of the geostrophic velocity equations and provided many examples of geostrophy by looking at 500mb height maps.

推导出地转速度方程的高度梯度形式，藉由观察500百帕高度地图举出很多地转的例子。

This is a walkthrough on how I did all Geppetto's diffuse maps.

这是一个关于演练如何我都Geppetto的弥漫性地图。

With Death guitarist Schuldiner adopting vocal duties, the band made a major impact on the scene.

随着死亡的吉他手Schuldiner接受主唱的职务，乐队在现实中树立了重要的影响。

But he could still end up breakfasting on Swiss-government issue muesli because all six are accused of nicking around 45 million pounds they should have paid to FIFA.

不过他最后仍有可能沦为瑞士政府&议事餐桌&上的一道早餐，因为这所有六个人都被指控把本应支付给国际足联的大约4500万英镑骗了个精光。
