submarine sonar 中文意思是什麼
submarine sonar
解釋
潛艇聲納-
Based on the real situation of submarine and antisubmarine warfare ( asw ), according to the classical design theory of transducer or transducer array, a sonar will be researched and made, which has the feature of more wider bandwidth, more lower operating frequency, more lager radiation acoustic power, more farther operating distance, more higher researching efficiency and more higher directive accuracy
本文根據現代潛戰和反潛戰（ asw ）的實際情況，按照經典的換能器和基陣的設計理論，研製聲吶，旨在擴展其頻帶寬度、降低其工作頻率、增大其發射功率、擴大其作用距離以及提高其搜索效率和定向準確度。 -
Joint application of dipping sonar and sonobuoy in answering the call to anti - submarine
吊放聲納與聲納浮標在應召搜潛中的聯合運用 -
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。 -
Evaluation was conducted at the basic point of efficiency of observational system, and expressed by probability of intercepting and capturing target by sonar equipment of submarine, which provided scientific foundation for organizing and commanding of missile attack about submarine
具體指示效能評估在觀察系統效能評估的層面上進行，用水聲設備截獲被打擊目標的概率來表示，為保障潛艇導彈攻擊目標指示組織指揮提供了科學的依據。 -
In civil engineering applications, for example harbor - constructing and bridge - building, need information of sea bottom. in military engineering applications, identification of sea bottom types are vary important for match field location, low - frequency sonar distance forecast, and choosing the location for submarine
在民用方面，修築港口，建設跨海大橋；軍用方面，匹配場定位、低頻遠程聲納作用距離預報、潛艇沉底隱蔽地點選擇等方面都有廣泛的應用。 -
