  1. The submarine noise detected by sonar consists of two parts : propeller - generated hydro - dynamical noise, which can be greatly reduced by improving the submarine rear shape ; radiated noise from the submarine structure excited by the centrifugal forces ( moments ) of rotatory machine, which is more complicated and influenced by many factors

    聲納所探測的潛艇噪聲包括兩部分，一是螺旋槳運轉帶來的水動力噪聲，二是潛艇主機工作時產生的不平衡力和力矩引起潛艇結構振動，帶動流場振動從而輻射噪聲。通過改進潛艇尾部線型設計，已將水動力噪聲降到比較低的程度，而結構噪聲則復雜得多，與許多因素有關。
  2. Three phase dry type power transformer, which make it with those features : safety, reliability, and energy saving, fireproof, flameproof, simple maintenance etc., the design is advanced ; the structure of products is reasonable and the outline is fine, the main performances of the products are much better than the national standards, for example, partial discharge level no - load loss, on - load loss, noise level, it is adaptable for application on heavy humidity and severely pollute places which are near to lake, sea and rive, as well as, high demand - fireproof, heavy load capacity place, such as : high building, airport, station, port, underground, hospital, electrical power station, metallurgy, shopping center, residential area and petroleum chemical industry, nuclear power station, nuclear - powered submarine
