The variety of these mudstone and shales is very complex in lacustrinehigh-frequency cycle.

这些泥岩和页岩在湖相高频旋回中的变化相当复杂。

Therefore, the Gutingkeng mudstone has good resistance under the impacts of high frequency vibrations.

因此，泥岩在高频率的反覆应力作用下，较不易破坏，故对於高频的震动具有较佳的抵抗力。

A comparison of the communication frequency bandwidth and the calculated MUF have been made.

本文首先简要介绍了1985年12月至1986年3月南极长城站与新乡的短波通信效果，可通信的时段与频段，并将频段与计算的MUF进行了比较。

It is found that the upper limit of the operational frequency bandwidth along the short great circle path which crosses the south-polar, region is approximately in accord with the calculated MUF and the other one along the long great circle path which crosses the north- polar region is different from the calculated MUF.

结果表明，经过南极区的短大圆路径的通信频段上限与计算的MUF基本相符；经过北极的长大圆路径的通信频段上限与计算的MUF有偏差。

When several different random sequences were used, the multi-address communication in the same range of frequency can be successfully achieved.

当不同用户采用不同的随机序列时，则可以在同一个频段内进行多址通信。

Because of their powerful anti-interference and multi-address, spread-frequency and FH are used for military and civil purpose more and more frequently.

由于扩展频谱通信、跳频通信极强的抗干扰能力和多址通信能力，使其在军事和民用上得到了越来越广泛的应用。
