They didn't get any kind of SOS signal, distress call.

控制台没有收到任何求救信号。

But that can only happen if there is transparency in markets and stocks so signals about prices and supply are accurately received.

收到潜艇最后求救信号的电报员是我的祖父。

But that summer, they were only picking up that Cherif was buying fake trainers from China, so it signaled a shift away from extremism into what was considered a low-level petty crime.

潜艇上的求救信号被设计成被动模式，也就是说我们得站在潜艇上才能检测到。
