A projection method is used to smooth out start and end points of the ruling line sets. With predefined Euclidean 6 space distances, the problem of ruled surface approximation from line sets in Euclidean 3 space can be converted into a least square B-spline curve fitting issue in Euclidean 6 space.

利用"投影"光顺法对齐直母线段族首末端点，再通过定义欧氏6空间下的距离函数，将欧氏3空间下的直线族逼近直纹面问题转换成欧氏6空间下B样条曲线最小二乘拟合问题。

According to characteristics of submarine pipeline data, all information is divided into two kinds, geo-spatial data and attribute data. Using identifier to connect two kinds of data, the problem of storing geo-spatial data in relational database is solved.

根据海底管道的数据特点，将海底管道的描述信息分为空间信息和属性信息两类，解决空间信息在关系数据库中的存储问题，并通过标识实现空间信息与属性信息的关联。

The results show that, when the volume of the secondary room is 1/3 of that of the primary room,the sound energy decay in the primary room is greatly in- fluenced by the secondary room at an aperture size of less than 10% of the wall,that the energy decay curve and the coupling con- stant in the primary room gradually change with the aperture size,and that the effect of the secondary room on the acoustics in the primary room is uniform.

发现在耦合空间体积与主厅体积比为1/3的条件下，当耦合窗面积与隔墙面积比小于10%时，耦合空间对主厅的声能衰减有较大影响；主厅的声能衰减曲线和耦合常数随开口的改变而逐渐发生变化：耦合空间对主厅各点音质的影响比较均匀。华南理工大学物理科学与技术学院；华南理工大学物理科学与技术学院广东广州 510640；广东广州 510640

In this paper, granularity in rough set theory is used to describe rules based on the concept of rough degree. A tool for knowledge dependent relation diagram is put forward. Then dimensional knowledge granularity decision space and the same construction mapping decision space based on multi-decision sorts is established, and decision algorithm based on KDRD and decision space is introduced. Finally, through combining with the technique of fault diagnosis, it is proved that the approach is very appropriate to the intelligent decision system.

本文利用粗糙集理论中的粗度概念，在对获取规则进行扩展性的粒度描述的基础上，提出了一种工具―知识依赖关系图，构造了n维知识粒度决策空间以及基于多决策类的同构映射决策空间，建立了基于KDRD和决策空间的决策算法，并结合机械故障诊断说明了本方法非常适于故障诊断等通过结论获取原因的智能决策系统。

The policy decisions were worked out on the basis of the digital elevation model, analysis of space, use of space database technology and theory of policy decision system, preserved space data of subsidence area of mining district and data experience of land reclamation, so as to acquire the rational land reclamation plans of the mining district and to provide information for environment evaluation.

从矿区塌陷坑的数字高程模型入手，通过空间分析，利用空间数据库技术和决策系统理论，保存矿区塌陷坑空间数据和土地复垦经验数据来进行决策，以期取得科学合理的矿区土地复垦方案，并且可为环境评价提供信息。

This paper built up an aggregate of time T, a target space A by reasonable assumptions and simplifications so as to convert each concrete thieves and burglars behavior into an abstract vector p, and then projected them to the decision space .

本文通过一定合理的假设及简化，建立时间集 T 、目标空间 A ，进而建立决策空间，从而将每一个具体的盗窃行为转化为一个抽象的盗窃计划向量 p ，进而将所有的盗窃行为映射到了决策空间上。

In the article, I study the relation between entrance and the form of architecture, definitude the influence to the form of building by entrance space, and try to offer an operational method of integrated design , and want to provide reference to design the form of architecture and space inside and outside.

本文意在从空间的角度研究入口与建筑形态之间的关系，明确入口空间对建筑形式构成或形式存在的影响，并力图对建筑形态的设计、构成提供一个可操作的"整体化"的设计方法，希望能对建筑形态和内外部空间的设计提供参考。

The dichromatic space groups of C2/c have been derived.

推导了与C2/c空间群有关的有色空间群，研究了聚丙烯分子链在它们中的排布，得出其中5种是聚丙烯α晶晶体结构可能存在的空间群；2。

The part of space belongs to the field intersected and bestrowed by architecturcal space and urban space, is provided with the diplex spacial attribute with architecturcal space and urban space, combining to undertake the dual space working talent.

复合公共空间是指现代城市建筑中对城市公众开放，承担一定城市职能并具备城市空间属性的特殊的建筑公共空间。

Exponential dichotomy describes a kind of hyperbolicity of the system. That is, the state space can be decomposed into a direct sum of two subspaces, which are continuous and invariant. And with the time evolving forward, the system is exponentially attracting in one subspace and exponentially expanding in the other subspace.

指数二分性描述了系统的一种双曲性现象：状态空间可以分解成两个连续不变的子空间的直和，随着时间的正向变化，系统在其中一个子空间上表现出指数压缩行为，而在另一个上面表现出指数扩张行为。

The split between the two groups can hardly be papered over.

这两个团体间的分歧难以掩饰。

This approach not only encourages a greater number of responses, but minimizes the likelihood of stale groupthink.

这种做法不仅鼓励了更多的反应，而且减少跟风的可能性。
