6. Rectangular attachment is put forward in order to solve the case when the feed point is near to the border of the conducting surface. it is deserved to mention that this new model is more simply than the one developed by Dr. Chen Qiang and both of them can obtain high accuracy.
6、为解决有限大长方形平面线面相连问题,文中提出了与圆形连接段互补的长方形 连接段,长方形连接段专门为解决馈电点距离边界非常近的情形而引入的。 值得 注意的是,长方形连接段的引入与陈强等人引入的连接段外加匹配段的模型相 比,前者更加简单,易于操作,同样有良好的精度。

Results given in this paper can be as an allowance standard in practical engineering about the feed point disp…
本文的结果对偶极天线馈电点横向、轴向位移及斜偏轴公差给出了一个工程上实用的准标。
"Any time you touch the feed point, it's kind of like squeezing the jugular vein on your neck, like the 'Vulcan hold' from Star Trek," said Banos.
“每次你接触到馈点,类似于用手指挤压你脖子上的颈动脉,就像星际迷航里面的Vulcan hold一样,”Banos说道。
There are more people who can work to increase the production, but beyond that point there are more people to feed than the production can produce, and that leads to a desire for expansion of the land available for cultivation.
越来越多的人从事工作,生产力得以提高,但是一旦突破临界值,花费就要超过所得了,它导致了对土地扩张的需求
