transmission bands meaning in Chinese
传动刹车带
通频带
透射带
Examples
- Many advantages make optical fiber suitable used as transmission medium of high - rate broadband services , such as broad transmission band , large capacity , low loss , strong immunity to interference etc . among optical access network , passive optical network ( pon ) is paid more attention throughout the world . it offers easily upgraded and low cost of lay , ope ration and maintenance . especially passive optical network based on atm ( atm - pon ) integrates the capability of supporting multiple qos services with atm and transparent transmission with pon
在光纤接入网中，无源光网络( pon )由于不采用有源节点、敷设和运行维护成本低且成本共享、对业务透明、易于升级等优点而备受世界各国的关注，特别是以atm为基础的无源光网络( atm - pon ) ，由于结合了atm多业务、多比特率的支持能力和pon的透明宽带传送能力，将成为实现未来宽带接入乃至最终实现ftth的重要方式。 - One of the key technologies of deep space communication is channel code . there are differences between deep space communication and the common space communication . because the former one has some characteristics , such as extending information transmission , and seriously reducing signal energy , it is necessary to ensure the information transmission band and the exactness by using the special means
信道编译码是深空通信中的关键技术之一,深空通信与一般的空间通信不同,深空通信具有信息传输时延大、信号能量衰减严重等特点,必须有特殊的手段保证其信息传输的带宽和准确。 - I also carried some research on the bragg grating composed by alternate left - handed material and right - handed material . in the reflective spectrum of the bragg grating , there exists bragg top zone ( with reflectance almost 100 % ) . however , i found that there exists some narrow transmission bands located in the bragg zone under some conditions
另外，这篇论文里还要讲到正负交替的材料组成的布拉格光栅也有很反常的现象，在光栅的反射谱上，我们不仅可以观察到和传统布拉格光栅相类似的布拉格平顶区，我们还可以看到在一定条件下，布拉格平顶区中会有一个很窄的反常透射区，也就是说只有很窄区域的波长可以透过光栅，而且中心波长是100 %透过。
