| 1. | The limited sensitivity of present pulsar surveys and the greater frequency drift make the more distant pulsars difficult to observe . 目前脉冲星普查的有限探测灵敏度和大的频率漂移,使我们难以观测到更遥远的脉冲星。 |
| 2. | Frequency drifts due to : dc voltage , temperature , vswr 频率漂移跟直流电压、温度、驻波比有关。 |
| 3. | Automatic frequency drift rejector 自动频率漂移抑制器 |
| 4. | Frequency deviation noise 频率漂移噪声 |
| 5. | Finally , its frequency shift is displayed by led , which is caused by mass loading effect 最后,显示其温度补偿后由于质量沉积效应所引起的振荡频率漂移量。 |
| 6. | Distribution automation using distribution line carrier systems - lower layer profiles - the spread frequency shift keying profile 配电线路载波系统配电自动化.低层剖面.扩展频率漂移键控剖面 |
| 7. | It makes the analysis of signal twitter and modulation very easy and the measurement of frequency drift and converting very simple 它使信号的抖动分析、调制分析非常直观,使频率漂移测量、频率转换特性测量变得十分简单。 |
| 8. | This approach the problem of conquers phase excursion and frequency drift that anciently adopts fixed frequency filter and its frame is simple 这种方法克服了以往采用固定频率滤波器带来的相移和频率漂移问题,而且结构简单。 |
| 9. | The over - current relay works to protect oscillation tubes and rectifier , when the current exceeds its limits . frequency deviation caused by faulty operation is also prevented 当电流超过限制值时,过负荷电流继电器自动保护振荡管和整流器,同时可以避免由不当操作所引起的频率漂移。 |
| 10. | The movement of the satellites causes doppler frequency to drift , the receiver usually tracks the signal frequency the receiver through phase locked loop , in order to can demodulate the signal 卫星运动造成多普勒频率漂移,接收机一般都采用锁相环来跟踪接收信号频率,以便能正确解调信号。 |
