A systematic analysis of the icosahedral hierarchic structure in the 3D icosahedral quasicrystal and its approximants have been made. There is an icosahedron at the center surrounded by 12 icosahedra. If two neighboring icosahedra are vertex-sharing, the multi-shell Mackay cluster consisting of 127 atoms will form. If two neighboring icosahedra penetrate into each other, the multi-shell Samson-Bergman-Pauling cluster consisting of 137 atoms will form.

系统地分析了三维二十面体准晶的近似晶体相中具有二十面体对称的等级结构，中心1个二十面体，周边12个二十面体，如两个相邻二十面体共顶点连接，得出的是由127个原子构成的Mackay球形原子簇；如两个二十面体互相穿插，得出的是由137个原子构成的Samson-Bergman-Pauling球形原子簇。

The industrialization of agricultural managing is a great breakthrough with overall importance and strategic meaning since the rural reform, Proved the new management style that can be in conformity with agricultural industrial structure adjustment of the present stage and operation mechanism by practice, It has 5 basic key elements, among them leading enterprises are the core of industrialization management, It is determining the level, level of industrialization, so should take the measure of promoting leadings enterprise of our province to develop : Market-oriented, bold in blazing new trails; Improve product quality and scientific and technological content; Set up steady interests connecting mechanism; Carry on resources and is combined and expand the scope of the enterprise ; Improve enterprise's managerial skill.

农业产业化经营是农村改革以来的一个带有全局性和战略意义的重大突破，是被实践证明能够与现阶段农业产业结构调整相适应的新的经营方式和运作机制，它有5个基本要素，其中龙头企业则是产业化经营的核心，它决定着产业化的层次、水平，因此应采取促进我省龙头企业发展壮大的措施：面向市场，大胆创新；提高产品质量和科技含量；建立稳定的利益连接机制；进行资源整合和扩大企业规模；提高企业经营管理水平。

The printed UWB antenna is comprised of a planar monopole radiator and the ground plane which are connected to a coaxial cable to launch RF signals. This kind of ground and antenna system is essentially an unbalanced design, where electric currents are distributed on both radiator and ground plane, and then leakage to the outer conductor of the feeding cable. The impedance matching and radiation pattern will be influenced in the low band, which are our focus. Finally, some techniques will be proposed to reduce the cable effect on the antenna performance.

进行超宽频天线量测时，吾人会利用同轴缆线连接到网路分析仪，这时的同轴缆线不只是扮演一个传输讯号的工具而已，由於单极天线的不平衡结构，对低频而言，接地回流电流会泄漏到同轴接地的导体外部，造成同轴缆线也是一个辐射体，影响到天线低频时的阻抗匹配与辐射特性，因此本论文将探讨同轴缆线对於天线一些参数的影响，并研究提出解决的办法。
