suspended fender 中文意思是什麼
suspended fender
解釋
懸掛式防撞物-
Again we take an imported 500 kw engine unit as the example. in this case baffle boards are stuck on walls inside the engine room, meanwhile baffle boards are also used as suspended ceilings. by doing so not only the amount of insulated sound of the fender structure is increased, but the reverberant sound in the engine room is also depressed ( normally by 3 to 5db )
我們仍以一臺500kw進口機組為例，油機房室內墻面設計為貼吸音板，同時用吸音板吊頂，經過這樣的吸聲處理后既增加了圍護結構的隔聲量，又可降低油機房內的混響聲，一般可有3 ~ 5db （ a ）的效果。 -
In a room without a window, there burnt a fire guarded by a high and strong fender, and a lamp suspended from the ceiling by a chain
在一間沒有窗戶的房間里，燃著一堆火，外面圍著一個又高又堅固的火爐圍欄，從天花板上垂下的鐵鏈子上懸掛著一些燈。
