HF

1.Check the maintenance indicator and the HF remote control unit and carry out the procedure to reinitialize the windows.

检查保养指示灯和高频遥控单元，并行车窗玻璃初始化。

2.A three dimension polarization filtering algorithm is put forward to suppress th e skywave interference in HF ground wave radar.

以高频波雷达为背景，提出了三维极化滤波方法，此方法能够滤除二维极化滤波不能抑制的干扰，扩大极化滤波的干扰抑制范围。

3.Much like the recent HF designed AF1’s, these do not feature the Fragment logo on the outstep of the heel.

象不最近，HF设计AF1东西，这些很多把脚后跟的「外-阶段」上面的Fragment标志作为特征。

4.The frequency of HF is determined by the ratio of respiratory frequency and heart rate.The results also indicated that nonadditivity of heart rate modulation by sympathetic an...

高频峰的频率是呼吸频率与心率之比，低频和极低频可能与交感和副交感神经调节心率的非可加性有关。
