描述

Traditionally, a surface is usually scatted in an array of 3D data points which are topologically connected by rows and columns to form a rectangular mesh. This method can't meet the requirement of description and measurement for some complex surfaces. On the basis of tracing border points, a new method is proposed to deliver 3D data points of surfaces, which are topologically constructed with optimum rectangular and triangular mesh. In order to measure surface efficiently and safely with NC machine, an optimization of measurement paths is proposed to avoid interference between the measuring tool and the surface with holes. The curve design is the basis of surface modeling.

数控测量技术的发展为测量自动化、集成化、智能化提供了可能，而对于复杂曲面的自动测量规划则是测量技术中的难点问题，平行截面等数目测点分布和四边拓扑测点分布规划方法，不论在测点分布的合理性上还是在网格结构的优化方面，均难以满足形状或边界较复杂曲面的离散化描述和曲面造型的要求，为了实现任意拓扑曲面的自动测量，本文对复杂曲面的合理离散化描述和自动测量问题进行了研究，提出了基于边界跟踪、优化网格的测点自动分布规划和四边、三角混合网格的生成方法：同时对具有孔洞或测量干涉凸台等非完整曲面的测量路径优化问题进行了研究，提出了路径优化方法。

The former is to formulate and model static for decision-making, while the latter is combined with the dynamic question soling process.

陈述性表示主要是的静态描述，对事实和规律的分析，知识表示与推理可以分开处理；而过程性表示，表示与推理结合，知识表示就是求解程序，是动态的描述。

You are project manager for a systems integration effort and need to procure the hardware components from external source. Your subcontracts administrator has told you to prepare a product description, which is also called a

你是一个致力系统整合的项目经理，需要从外面供货商采购硬件模块，你的外包商管理员已经告诉你需要准备一个产品描述，该产品描述也称为一个

One underlying problem in hydraulic engineering is that we havent a strict theory to control the connection quality of hose assembly, i.e. we have no reasonable mathematic models in the designing of hose connector and the controlling of its swaging quantum.

液压工程中一个突出的问题是，对胶管总成连接质量控制没有一个严格的理论界定，表现为：①对胶管接头设计没有数学模型描述；②对总成压缩量没有数学模型描述。

Descriptive statistics involves tabulating, depicting and describing collections of data.

描述统计学涉及对所收集数据的制表，制图和描述。

In tiffs paper, inspired from the position-numeral description in computer, the step s expression of the search algorithm was gained through reasonable conversion of some interrelated rules, Based on inheriting the advantages of traditional Hill Climbing, a new way to search the kinematic inverse solution of multi-joint robot -intelligent hill climbing, was put forward.

本文从计算机原理中位置数制的描述获得启发，将其中的某些规律进行合理的转换，形成搜索算法的步长表达式；在吸收传统登山优点的基础上，提出了求取多关节机械臂运动学逆解的新算法——智能登山法，并对算法进行了描述，写出了完整的通用流程图，运用该方法求取机器人运动学逆解，无需矩阵运算、三角变换；收敛速度快，适于实时控制，仿真试验验证了该方法的可行性、实用性。

Descriptions of the 1948 war tended to suggest that Palestinians either left their homes voluntarily, selling them to Jews, or were encouraged to leave by other Arabs—rather than, as sometimes happened, being forced out violently. Maps of pre-1948 Palestine sometimes underplayed the extent of Arab habitation, while maps of modern Israel never included the "Green Line", the pre-1967 border; this makes the occupied territories of Gaza and the West Bank look as if they were an integral part of Israel.

对1948年战争的描述则往往暗示，巴勒斯坦人要么是自愿离开家园并将之卖给犹太人，要么是被其他阿拉伯人鼓动离开——而并非象时不时发生的那样是被暴力地强行驱出。1948年之前的巴勒斯坦地区的地图有时候对阿拉伯人居住范围描述得并不充分，当现代以色列的地图不再包括&绿线&——1967年之前的边界——部分在内的时候，就使得被占的加沙和西岸地区的领土看起来是以色列不可分割的一部分。

TInt aLength The new length of the descriptor and the number of binary zeroes to be copied into it.

描述符的新长度、将要被拷贝到描述符中的二进制0的个数。

The descriptor is filled with the specified number of binary zeroes.

描述符将被指定个数的二进制0填充。描述符的长度不被改变。

Against it, it is necessary to make some artificial distinctions.

为了描述景观、描述它的形成，它的作用，以及反对它的各种力量，做一些人为的区别是必要的。

They weren't aggressive, but I yelled and threw a rock in their direction to get them off the trail and away from me, just in case.

他们没有侵略性，但我大喊，并在他们的方向扔石头让他们过的线索，远离我，以防万一。
