查询词典 congregate

At the designed operating frequency, the refractive index approximates zero, which makes the nondirective electromagnetic wave tend to approximate plane wave along the normal direction of the superstrate and congregate the radiation energy. The gain patterns of the rectangular waveguide antenna and arrays with and without DNG structure are compared.

比较了双负媒质结构加载前后矩形波导天线及其阵列的增益方向图，数值仿真和测量结果表明，天线的前向增益得到显著的提高，同时对后向辐射也有一定的抑制效果。

The DNG structure unit is composed of square split ring resonator and strip wire. The modified NRW method is used to extract the equivalent permittivity, permeability, and refractive index from the scattering parameters of the two-port waveguide with DNG structure. At the designed operating frequency, the refractive index approximates zero, which makes the nondirective electromagnetic wave tend to approximate plane wave along the normal direction of the superstrate and congregate the radiation energy.

以方形的SRR环和金属条带构成双负媒质结构单元，使用修正的NRW方法，通过放置双负媒质结构的二端口波导的散射参数，提取了等效的介电常数、磁导率和折射率，在所设计的工作频率，折射率接近于0，可以将原本发散的电磁波整理成趋近于覆层面法线方向的近似平面波，起到能量汇聚的功能。

In a word, NaCl could inhibit the growth of C. roseus seedlings, and disrupt their ion balmier. To avoid the damage caused by NaCl stress, the seedlings would congregate excessive Na(superscript +) and Cl(superscript -) in their epidermal cells.

盐胁迫能够抑制长春花幼苗生长，打破其体内的离子平衡，但植物为降低盐胁迫的伤害而将过多的Na和Cl聚集于表皮细胞。

All they can do is yell or congregate on fairways brandishing their sickles.

他们只能大声抗议，或者是聚集在球道上，挥舞着手中的镰刀。

They congregate in flocks that can number in the hundreds of thousands, but flamingos generally remain monogamous for life.

它们聚集成群，可以数以十万计，但火烈鸟一般保持一夫一妻制的生活。

From simulations and data of fire site, most air preheater fire often appear when boiler is started in cool state and standby which fuels of insufficient combustion coagulate and congregate on the parts of air preheater. When the temperature of smoke inpouring air preheater increases, aggregate fuels and sediments will combust in stated temperature conditions. It is called the second combustion of air preheater.

这些起火起因于燃料油的不充分燃烧，其结果是未充分燃烧的燃料油凝结和聚集在空气预热器的部件上，当进入空气预器的烟气温度增高时，沉积的燃料油被烘烤，当达到一定温度条件时，则可点燃这些燃料油污沉积物，造成火灾发生，这通常被称为空气预热器的二次燃烧。

英国的度假小丑们会聚集到同一个地方；这是《纽约时报》从克利特岛的马利亚发回的报道。

Oxford University once famously claimed to have been founded by Alfred the Great in the 9th Century, but in fact, the University as we know it today began to take shape in the 12th Century when English Scholars were exiled from Paris University and began to congregate at Oxfords Abbeys and Priories, which were buy then already established centers of learning.

牛津大学曾经一度盛传是由阿尔弗来德一世在9世纪建立的。但事实上，我们今天所知道的牛津大学初建于12世纪，当时一群英国学者从巴黎大学流放过来，云集于牛津的教堂和修道院中，在那时候教学中心就已经建立起来了。
