天线长度 meaning in Chinese
antenna length
length of antenna
Examples
- Because waves can vary from 18 feet for channel 2 television to three inches for cellular telephony , proper antenna length is key to reception
因为电波波长从第二频道电视用的5 . 5公尺到行动电话用的7 . 6公分都有,所以适当的天线长度正是收讯品质的关键。 - The simulated results show that we can improve the sensitivity by setting the optical bias at / 2 , reducing the gap of electrode , increasing the overlap integral factor , reducing the insert lose , adopting suitable segmentation number , increasing the electrode length , increasing the optical power , reducing the wavelength and the relative intensity noise and reducing the receive bandwidth ; obtain the wider bandwidth utilizing reducing the electrode length and the capacitance of modulator , segmentation the electrode ; increase the dynamic range using lowering noise , increasing the optical power at the detector and lower optical bias
通过计算得知,使传感器相位偏置为/ 2 ,减小电极间距,提高电光重叠因子,减小器件插入损耗,采用合适的分段数,增加电极长度,增大光功率,降低激光的波长,减小相对强度噪声,减小接收带宽,对提高灵敏度的效果是非常明显的。而减小天线长度,降低调制器电容,电极分段,都可以获取较大的带宽。降低系统噪声;增加到达探测器的光功率,采用较低的光学偏置,都可以增大线性动态范围。
