现在我真的很沉迷机械装置，但是你可以想象重物掉落的时候会带动桨轮旋转。

Now I'm really fantastic at drawing this mechanical device, but you can imagine that dropping weight can cause a paddlewheel to turn.

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.

机械式螺旋桨动力仪已不能满足船模试验自动化测量要求。

The mechanical type propeller dynamometer is unable to satisfy the requirements of the automatic measurement for the ship model tests.
