| 1. | In the end some cases that several wire antennas attached to an arbitrary faceted conducting body are analyzed and calculated and some useful conclusions were get 在最后,作者对一些实例进行了具体的分析和计算,得出了一些很有用的结论。 |
| 2. | Ground a ground is a connection , either intentional or accidental , between an electrical circuit and the earth or some conducting body serving in place of the earth 接地接地是电路与地面或地面上的导体的连接,可以是有意的也可以是意外的。 |
| 3. | The other is that the conducting body is electrically large . we can solve this case by high frequency methods or hybrid methods of high and low frequency for example the hybrid of mom and gtd 另一种情况是金属多面体是电大尺寸,此时可以通过高频或高低频混合的方法来解决,例如矩量法和几何绕射混合( mom gtd )的方法。 |
| 4. | In many cases vehicles , ships and aircrafts can be seen as arbitrary faceted conducting bodies . in this paper the characteristic of several wire antennas attached to an arbitrary faceted conducting body and the infection between them are analyzed 在很多情况下,车辆、舰艇、飞机、卫星等物体都可以近似看成金属多面体,因此,本文主要研究金属多面体上多根线天线的特性,分析他们之间的相互影响。 |
| 5. | It is emphasis how to calculate three - dimensional radar cross section ( rcs ) by the fma because of its superiority . the universal program has been accomplished by the fma , which may calculate the radar cross section of all kinds of shapes three - dimensional conducting bodies 由于快速多极子法分析三维物体电磁散射的优越性,本文重点研究了如何用快速多极子法求三维导体的散射截面,利用快速多极子法编出了能够计算三维导体单站散射截面的通用程序。 |
| 6. | In this dissertation , the calculation of the electromagnetic radiation and the electric magnetic compatibility of the conducting body with the wire antenna attachment is discussed , which is based on the classic moment method technology while using the visual c + + as the programming environment and the programming tool 本文以经典的矩量法为理论基础,以microsoftvisualc + +为主要编程环境和编程工具,计算插有细天线的金属导体的电磁辐射和电磁兼容特性。 |
| 7. | Competitive force is the ability with which one conduct body and other bodies strive for the same resource ( or some same resources ) . it can be deemed as the micro - behavior of a profit body . the micro - behavior not only depend on its own ability , but is also limited by its surroundings . connotation of competitive force have both micro - behavior factors and macro - environment forces 竞争力是一个主体与其他行为主体竞争某种(些)相同资源的能力,可以理解为某个利益主体的微观行为。这种微观行为不仅要靠自身的能力,还要受到很多环境要素的制约。竞争力的内涵既有微观行为因素,也有宏观环境因素。 |
| 8. | When we analyze the characteristic of several wire antennas attached to an arbitrary faceted conducting body we must divide it into two cases . one is that the conducting body is electrically small , the mutual coupling and infection between the antennas and conducting body are very obvious . so we must model them precisely and the shape of the conducting body , the length and location of the antennas etc . are must be tak en into account 金属多面体上有多根线天线分两种情况,一是金属多面体是电小尺寸,此时,天线和金属多面体都是属于精细结构,天线之间的互耦以及金属多面体对天线影响都非常明显,所以金属多面体的形状以及天线的长短、位置等对计算的结果影响非常大,因此必须精确建模,把所有的因素考虑在内。 |
| 9. | Characteristic analysis of single wire antenna attached to a conducting body or plate is done in many papers but very few people pay attention to the case of several wire antennas . a deep research for several wire antennas attached to an arbitrary faceted conducting body is made in this paper 许多专家、学者都对金属物体、金属平板上的单根线天线的特性进行了许多分析和研究,但是多根线天线的情况却研究得较少,本文对金属多面体上有多根线天线情况进行了深入的研究。 |
