然而，正如由下面的汇总表所显示，使用分布式黑名单时发生“误否认”的频率要比其它我所测试的技术多很多。

As the summary table below shows, however, false negatives are far more common using distributed blacklists than with any of the other techniques I tested.

基于相位转换技术的多模分频器由于其在工作频率和功耗中能更好地折中而得到广泛的应用。

Multi-modulus divider(MMD) based on phase-switching technology finds wide application due to good trade-off between operating frequency and power consumption.

随着人们对通信需求的不断增长，带来了如何有效地利用频率问题，同时也产生了越来越多的多址技术。

With the increased need for communications come a need for the efficient use of tile frequency spectrum and the more multiple access technique.
