floating body 【物理學】浮體。

floating bridge

They include the ship kelvin wave pattern and wave resistance , the interaction of surface waves with floating bodies , the seakeeping of ships high - speed vessels and offshore platforms , the evaluation of the drift forces and other nonlinear wave effects responsible for the slow - drift responses of compliant offshore platforms and their mooring systems designed for hydrocarbon recovery from large water depths 這包含了船波和波的阻抗、波和浮體的交互作用、高速行駛船舶與近岸結構物之耐海性、拖曳力評估及其他造成順應式近岸結構物緩慢飄移現象的非線性效應,與結構物設計于深海中以重獲碳氫化合物之錨定系統。

By hydraulic modeling , this paper describes studies on the stability of a floating bulkhead operating in standing water and flowing water , and it ' s hydrodynamic stability characteristics that distinguish in standing water from in flowing water ; and direct measurements of the forces acting on the model floating body during floating and sinking is taken . as a result , the rotation stress curves are produced and analyzed ; to provide data for optimum operation schedule analyses of the sluice , the relationship of the impact forces acting on the side wall of the gate and the running speed is studied ; the reasons of unstably uplifting of the bulkhead are discussed and the method to solve the problem is also given in this paper 本文結合常州新閘防洪控制工程水工模型試驗,系統分析了浮箱門在靜水和動水中的穩定性及其影響因素,指出靜水穩性和動水穩性的不同特點;試驗測定了浮箱門動水運行時的受力情況,給出并分析了定位過程轉動力的變化過程曲線;根據浮箱門啟閉速度與門體和岸墻之間撞擊力大小的關系,選擇合理的動力設備,為設計和工程實踐提供可靠依據;分析浮箱門難以穩定上浮的原因,并給出解決方案。

The major work is as follows : solution of two dimensional radiation or diffraction fluid field . this thesis extends multipole expansion method to adapt to disturbed fluid fields of 2d floating bodies with asymmetric forms , which is applied with symmetric forms originally . and given the solution of potential velocity and hydrodynamic pressure of radiation and diffraction fluid fields , which is incited by a 2d arbitrary form , actual application field of the multipole expansion method has been enlarged 關于二維擾動流場的求解:將通常僅適宜求解具有對稱形狀二維物體擾動流場的多極展開法(保角變換方法)擴展至非對稱形狀二維物體,給出了任意形狀二維物體的輻射和繞射流場的速度勢及水動壓力的頻域解,進一步擴大了多極展開法的實際應用范圍。

Grant , 33 , said thursday that suns team doctor thomas carter will perform the operation friday to clean out any calcification in the tendon of the knee and any floating bodies within the joint 33歲的格蘭特在周四的時候說太陽隊的醫生托馬斯.卡特將會在周五的時候動手術來清除膝蓋里鈣化的肌腱以及關節里的碎片。

On the side the hydrostatic forces that cause a floating body to “ rise “ will be less 身體在一側將會使“升起”一個浮動身體的流體力學的力量減弱。
