您要查找的是不是:
- The bigger the refractive index ratio of two primitive dielectrics of one-dimensional photonic crystals is,the narrower the transmission band is. 一维光子晶体的两基元介质折射率比值越大,产生的透过带越窄;
- This paper points out that if the f s=2f sc of sub-Nyquist Sampling and DPCM_encoding is used for TV signal, the bit rate may be more compressed and transmission band is reduced. 本文指出,若在有效区内对电视信号采用亚奈奎斯特取样,并采取DPCM编码,就可以大大压缩码率,降低传输带宽。
- effective transmission band of channel 通路有效传输频带
- Devices with multiple transmission bands are designed in three ways: intermixture, mixture, and remotely couple surface plasmons. 利用混成排列、分开混成排列、远控式表面电浆,成功的设计了宽穿透带与多穿透带的光电元件。
- We also discuss the analyzing method for the expen se of network transmission bands, which is the basis for designing DIS network. 并讨论了协议数据单元PDU对网络带宽资源的开销分析方法,以便于系统组网设计。
- To further verify transmission bands were caused by positive refractive index or negative refractive index, the Snell refraction experiment was taken. 为了确定功率透射实验中出现的两个透射峰是由正折射率引起还是负折射率引起的,随后又进行了棱镜实验。
- Firstly, the transmission measurement in the parallel-plate waveguide was carried out and there existed two transmission bands at 7.8GHz-9GHz and 10GHz- 13GHz. 在进行了平行板波导中功率透射实验后,发现在7.;8GHz-9GHz和10GHz-13GHz频率范围,各存在一个透射峰。
