查询词典 transmission bands

The transmission ratio exceeded 95% in near-infrared range, so the LCAS:Tm(superscript 3+) glasses can be used as high transmission optical glasses. The integral emission cross-sections outclassed 10^(-18)cm, the fluorescent ratios were higher and the radiative lifetimes were lenger, to the glasses are possible to be used as new laser function materials. The new strong and broad emissive bands for 400nm to 680nm emerge in the emission spectra of the another glasses samples.

高达95%以上近红外透过率表明，LCAS：Tm(上标 3+)玻璃可作为近红外波段高透过率光学玻璃；远大于10^(-18)cm的积分发射截面、较高的荧光分支比与能形成粒子数反转的荧光寿命表明，LCAS：Tm(上标 3+)玻璃可能成为一种新的激光功能材料。

Only one drawback, in order to utilize the benefit, the client chipset needs to have similar features of dual band support (example: Dlink DWA-160 USB adapter) so that it can detect and decode the data transmission for these two bands simultaneously.

只有一个缺点，以便利用效益，客户端的芯片组都需要有类似功能的支持双频（例如： Dlink妇女事务部- 160 USB适配器），以便它可以检测和解码器的数据传输这两种波段同时进行。

When you search the World Wide Web for magnetic loops, you usually run into magnetic loops meant for transmission in the upper ham bands, perhaps 14 MHz and above.

当你搜索互联网寻找磁环天线时，通常找到的用于HAM发射更高频段的（也许14MHz及以上）磁环天线。

The localization length is found to be very small in gaps and much larger in bands, the transmission decreases in bands while increases in gaps as the disordering degree increases .

当无序度较大时，局域长度不仅和随机度、带隙有关，还受到材料的影响；若光束斜入射，TE模的局域长度要远小于TM模对应的值，且其最小值向短波方向移动。

Its shown that, on normal incidence, the photonic crystals containing negative refraction materials have wider photonic band gaps which is different from the case of traditional photonic crystals, which have narrow transmission bands.

第四章从麦克斯韦方程组出发，推导了光在单负材料周期性结构的传输矩

Transmission bands; ultimate gain; output-power; output voltage RMS

通频带；最大增益；功率输出；输出电压有效值

The main properties of one-dimensional photonic band gap structures that include layers of negative refraction material are analyzed from the explicit dispersion equation. The results show that the photonic crystals containing negative refraction materials have wider photonic band gaps which is different from the case of traditional photonic crystals with narrow transmission bands when the two layers have the same optical thickness.

从色散关系出发，通过数值模拟计算研究了由正折射率材料和负折射率材料交替组成的一维光子晶体的能带结构与光子晶体的结构参数之间的关系。

The paper extended researches the microstrip six-port net project deeply, ADS tools are adopted to model and simulate this project, and then the paper analyses the characteristic of radio channel both transmitter and receiver, analyses the extended transmission bands and simulates the adaptability, then designs lumped-distributed microstrip filter.

文中对微带六端口射频通道方案进行深入的扩展分析，采用ADS建模及仿真研究，分析了发射通道和接收通道的特性，通过对通频带扩展及适应性仿真的分析，设计了集总—分布式微带滤波器，最后也与零中频混频方案比较了各自的差异性。

In overlay cognitive radio, secondary users harness unused spectrum bands for their transmission; in underlay cognitive radio, an ultra-wideband transmission with very low power spectrum density is employed by the secondary user to minimize harmful interference to the primary users.

认知无线电和动态频谱接入网络因此应运而生，成为近期无线通信和网络研究的热点。通常的认知无线电技术主要采用两种频谱接入方式：Overlay和Underlay。

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.
