   • 你要知道，潛艦是看不見東西的。我在深海，水太深是看不見的，所以，只能靠聲納。聲納其實是一個很玄的東西，特別是在海裡面的時候，因為有變溫層，有溫度的關係，有海水的密度的關係。你只要鹽分的密度不同，海水的溫度不同，那個聲納折射出來的東西基本上跟跋桮準不了多少，比跋桮略準一點。 [MSC, trad.]

     You have to understand, submarines are blind. When you enter the deep ocean, you can't see anything when the water is too deep and you must rely on sonar. Sonar is actually a very finicky thing, especially when used in the sea. This is because of the temperature change layer, which is connected to the temperature and oceanic water pressure. If the salt content density changes or if the ocean water temperature changes, the results of the sonar refraction will be essentially be little different from throwing poe, perhaps a tiny bit more useful than throwing poe.
