随着低噪声安静型潜艇的出现，传统的水下目标探测手段面临着挑战。

Along with the appearance of the low noise peaceful submarine, the traditional undersea detection methods face the new challenge.

指出螺旋桨噪声、水动力噪声和设备机座机械噪声被有效抑制后，管道系统便成为“安静型”潜艇的主要噪声源。

Then the pipe system becomes the main noise resource of quite submarine, when propeller noise, hydrodynamic noise and machinery noise of facility base are controlled effectively.
