单极的

This produces a waveform of one polarity operating at a frequency twice that of the mains supply.

经过整流后得到的是一个频率为交流电源两倍的单极波形。

In Chapter 4, the meander line and fractal technique are introduced to the design of antenna.

设计了一种用双杆作辐射体的平面组合单极子天线，具有结构简单、尺寸小、频带宽等诸方面的优点。

The method of moments is used to investigate the resonant characteristics of the antenna.

提出一种新型单极子天线，天线的辐射主体由双弯折线构成，通过矩量法研究天线的谐振特性。

The charge isn't attached to any physical object, but it behaves just as a monopole would.

这个磁荷并不附着在任何的物体之上，但它的行为就如同一个磁单极子一样。

Heat measurements in one paper 1 also support the monopole argument.

一篇论文中的热分析也支持磁单极子的论点。

Thereby it was possible to reduce the density of the string networks and promote the monopole dissociation.

这样就可能减少网状弦的密集度，还能加强单极子的分解

After that, we focus on the designs and calculations of the ultra-wideband monopole antennas in order to figure out ways to improve the performance of the antennas.

之后，我们重点介绍单极子天线的设计计算方法和改进优化方式，并给出若干设计实例，进行数值仿真和实验的验证。

In order to overcome the shortcomings of the monopole antennas, a methods of quasi-fractal is used, which decrease the resonant frequency.

为此，对HF频段的单极子天线进行准分形，有效地降低了天线的谐振频率。

The obsolescent unipolar world economic order should be replaced by a system based on the interaction of several major centers.

即将过时的单极世界经济秩序应该被以几个主要中心相互作用为基础的系统所替代。

Today, we have a number of regional balances overlaid by a unipolar pattern.

今天，我们所拥有的很多区域均衡都是在单极所覆盖的。

Cynanchum Lingtai apricot production in the average weight 65 grams, the brightly-colored fruit, juicy rich, sweet-sour taste, sweet from the nucleolus, when the late Qing Dynasty famous Shaanxi, Gansu provinces, the Qing imperial court Tongzhi tribute for years.

灵台生产的牛心杏平均单果重65克，果实色泽鲜艳，汁多味浓，甜酸适口，离核仁甜，清末时就驰名陕、甘两省，清同治年间曾为朝廷贡品。

Chenopodium album,Solanum nigrum, and Amaranthus retroflexus were very susceptible to the herbicides. Polygonum persicaria and Abutilon theophrasti were relatively less susceptible to the herbicides, and Lycopersicon esculentum was not susceptible to it. The relationship between reduction rates of weed biomass and PPM values of weed leaves 2,4, and 6 days after treatment was established.

供试的6种杂草对该混剂的敏感性存在显著差异：红心藜Chenopodium album、龙葵Solanum nigrum和反枝苋Amaranthus retroflexus对该混剂最敏感，ED90值分别为47.65、71.67和29.17g/hm2；春蓼Polygonum persicaria和苘麻Abutilon theophrasti敏感，ED90值分别为96.91、114.20g/hm2；而番茄不敏感。
