Frequency range -MHz的意思|示意

This part of the project is searching the nearest 1000 likely stars with high sensitivity for signals in the frequency range 1000 to 3000 MHz.

这部分项目搜寻离地球最近的1000颗可能存在的恒星，这些恒星对频率范围在1000到3000兆赫内的信号有着较高的灵敏度。

Only little differences in the frequency range under 1 MHz at different current peak values (Fig. 14 and Fig. 15) can be noticed except from some resonance frequencies.

除了几个谐振频率，在1兆赫兹以下的频带，干扰信号在不同峰值电流下测试出来的结果仅有微小的差别(图14和图15)。

Its output frequency can be adjusted continuously around the center frequency (56.448 MHz) over a range of 65 KHz.

输出频率可在中心频率(56.448兆赫)附近连续微调。调整范围为65千赫。

Its frequency tuning range broadened by Zeeman effect was more than 2500 MHz.

激光器单频可调范围经塞曼效应展宽后达2500兆赫以上。

In the low frequency range (1 Hz to 1 MHz), however, the inductor value becomes very large and the inductor itself gets quite bulky, economical production difficult.

然而，在低频范围(1hz至1mhz)中，电感器值变得非常大，并且电感器本身变得非常庞大，经济的生产困难。
