The computer model finds that mid-frequency sonar is mostly filtered out for the whales, while the higher frequencies the animals use for hunting appear to be unimpeded by sonar.
电脑模型表明,突吻鲸能过滤掉声纳大部分的中频声波,而声纳也不会影响这些鲸鱼用来捕猎的高频声波。

HuntingHunting is a phenomenon that can occur upon load changes in which the frequency or the voltage continues to rise above and fall below the desired value without reaching a steady-state value.
游车游车是一种在负载变化引起的频率、电压高于或低于期望值,无法达到稳定的现象。
