1. We use the term bandwidth to represent such a frequency range.
   我们用频带宽度这个词来代表这样的频率范围。
2. The other circuit is designed to resonate close to the desired frequency.
   把另一线圈设计成在所有要求的频率范围内可与之谐振。
3. The advantages of frequency approaches to registration are rapidness and high precision.
   频域配准方法具有配准精度高和速度快的优点。
4. The high frequency signal can be decomposed, and the frequency field can be divided into tinier ones with the emerging of wavelet packets.
   摘要小波包的方法能对高频信号进行小波分解，给出了频域带更精细的划分。
