基本单元

Finally, this paper splits the system into some basic control modules according to the characteristic of the system.

最后，本文按照整个控制系统的特点把系统分割为一些基本控制单元。

Because Matlab uses complex matrix as its basic unit, we provided the matrix form of the Bezier curve and tensor product Bezier surface, and presented the ways to achieve them by using Matlab. On such a basis, we obtained the algorithm, made feasible programs and demonstrated them by concrete examples. Such a study aims at promoting the realization of CAGD toolbox by using Matlab.

由于Matlab的基本编程单元是复数矩阵，因此首先归纳出了一维Bezier曲线和二维张量积型Bezier曲面的矩阵表示形式，在此基础上形成算法，编写了可实现的程序，随后以具体实例的形式给予验证，最终得到了满足要求的曲线和曲面，以期能够推动Matlab的CAGD专业工具箱的产生。

The basic process of tetrahedral octree spatial decomposition for using directly in finite element analysis is described.

然后在此基础上详细论述了正四面体八叉树法划分空间、直接生成四面体网络单元的基本过程。

On the base of other researcher, the *** from the basic equations of stable current field to derived the expressions of boundary problems under 3-D condition. Without considering the EM effect and using the generalized variation principle, we can get the corresponding variation equation. Thronging subdivide the 3-D model, interpolation, analysis, and general synthesis with the triangular prism element, we can carry out the simulation on frequency-domain IP\'s parameters under level and undulate topography.

在前人工作的基础上，在忽略电磁效应的情况下，从稳定电流场的基本方程出发，推导了三维区域满足的边值题目，用广义变分原理得到相应的变分题目，通过用三棱柱单元对大地模型进行剖分、插值、总体集成，最后解方程，得到每个节点上的复电位值，最后实现了水平和起伏地形等条件下的激电参数的数值模拟。2。

The quotation of terms of works for a transmission project can be determined by a term of a fundamental construction unit times effecting factor.

一个输电工程项目的工期定额可以用一个基本施工单元的工期乘以影响系数来确定。

In traditional Jiarong Zang nationality villages, inheritance and marriage rules which are represented by the "house name" make core family as the basic unit, and rule out the possibility of extended family and religious organization. Kinships among them become loose,but the rate of marriage alliance within the village is very high because incest taboo which is represented by the "house name" gives villagers more freedom to choose their marriage. And villagers also want to control the cost of marriage.A Jiarong Zang nationality village is actually a heavily heterozygote of blood-relation, marriage and place, a boundary of human relations.

在传统的嘉绒藏寨中，以"房名"为象征的继嗣和婚姻规则使核心家庭成为嘉绒社会最基本的单元，并且排除了扩大家庭和宗族组织的存在，亲属关系呈现为相对松散的状态，但以"房名"为记号的乱伦禁忌使绒人在婚姻选择上具有更大的自由，加之绒人降低婚姻成本的考虑，导致了高比率的寨内联姻，一个嘉绒藏寨实际上是血缘、姻缘和地缘的高度重合体，是人际关系的空间边界，日常交往体现出寨内的高度趋同性和整体性。
