shortwave

Can this radio receive shortwave?

这个音机波吗？

The two transpolar shortwave time signal circuits,Moscow and Irkutsk to the Great Wall Station in Antarctica, are used to study the fading characters for shortwave long circuit.

为了研究过极区的波长电路的衰特性，在南极长城站测莫斯、依尔库茨克的波授时台信号，并给出各频率对应的衰深度、衰率、衰持续时间等参数的统计特征和衰幅度分布曲线。
