查询词典 bandwidth

The high bandwidth and large number of sub-carriers used for DVB-T and DVB-H allow for the reduction of several kilohertz of spectrum around DC without noticeably degrading performance.

高宽带和大量子载波频率的使用，使 DVB-T 和 DVB-H 在直流电中允许数千赫兹的缩减，而没有显著的不良表现。

"Recognising that the web is richer and more bandwidth intensive than it has been historically, we are pleased that Comcast understands these changing traffic patterns and wants to collaborate with us to migrate to techniques that the internet community will find to be more transparent," said Eric Klinker, BitTorrent's chief technology officer.

&认识到网络是丰富和更密集的带宽比它已在历史上，我们高兴地看到，康卡斯特理解这些变化的流量模式，并希望与我们转移到技术，在互联网上社会将发现，以更加透明，&说：李家祥klinker好， BT的首席技术官。

The bandwidth of the overall system will limit the amount of information that can be transmitted through the system and the amount of noise that can enter the system.

在整个系统的带宽限制的信息，可通过该系统传输和噪音，可以进入该系统的款额。

Time, bandwidth and memory resources are occupied to result in the link block as well as the deluge of unhealthy messages. Currently, there are some mature filtering methods which adopt software automated filtering and user setting rules.

目前已有一些比较成熟的过滤方法采用通过软件自动过滤与用户设定规则的方式，但这类软件存在着明显的不足：它需要人工设定过滤规则，这要求用户或管理员有较强的专业知识，还要求用户能随着垃圾邮件情况的变化不断调整这些规则。

Pseudo-random multi-frequency signal is invented and named by academician He Jishan. The bandwidth of PRMF signal is controllable, it's energy concentrates on several frequencies, which are equally spaced on log scale coordinates.

何继善院士发明和命名的伪随机多频信号，由于其带宽可控，能量主要集中在数个在对数坐标上呈等间距分布的频率上，是电法勘探的理想场源。

Pseudo-random multi-frequency signal is invented and named by academician He Jishan. The bandwidth of PRMF signal is controllable, it's energy concentrates on several frequencies, which are equally spaced on log scale coordinates. It is ideal excitation source for electrical exploration.

Through the designed bandpass filter, it can increase the total bandwidth.Moreover, the dual-band bandpass filters are designed by using the impedance ratio of stepped impeedance resonator and meander of transmission Line.

传统上，平行耦合微带线带通滤波器，是两段四分之ㄧ波长传输线等效成一个导纳转器，因为导纳转换器并不具随频率改变的特性，此种仅适合窄频宽时较准确，用在大频宽时，实际的频宽会缩小，经由改善后，可提高频宽。

You'll have megabits of bandwidth to essentially every human pair of hands in the world. For knowledge, for entertainment, for all of the things that people care about.

这个世界上的每个人手中都有宽带资源，知识、娱乐和其他人们感兴趣的内容。

If you do find a movie that you'd like to watch, you must have a bandwidth speed of at least two megabits per second to download it instantly; millions of broadband homes have slower connections than that.

如果你真的找到了一部自己喜欢的影片，那么带宽速度至少要达到每秒2兆，才能实现快速下载。而许多家庭的宽带下载速度根本达不到这一要求。

At the saxne time, meLS VPN----a solution for integrated model is discussed indetail, including network comPonents of MPLS VPN and its operation mode. There arealso some problems that must be solved to build a MPLS VPN, such as customer addressspace overaPping, netWork accessibility constraini, VPN route uPdating, saving ofbackbone bandwidth, reducing of complexity of PE rooters and accessing Internet fromVPN, etc. MPLS VPN can solve all the problems, as well as bring us some values inscalability, imPlemotation and maintenance.

在此基础上，详细阐述了集成模型的解决方案——MPLS VPN的工作原理，包括MPLS VPN的网络构成和运行模式，对实现虚拟专用网所面临的问题：用户地址空间重叠、网络连通性约束、VPN路由信息更新、节省骨干网带宽资源、降低PE路由器处理的复杂性以及如何在虚拟专用网内访问Internet等提出了解决方案，并对MPLS VPN在扩展性、可实现性、可维护性方面的优势进行了说明。

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。
