period resonance 中文意思是什麼
period resonance
解釋
周期共振-
The numerical results indicate that the deformation within the solid inner core is very small. however, in the fluid outer core, the changes of the displacement with relatively low spherical harmonic degree ( n < 10 ) is very complicated via the radius, due to the resonance near the eigenfrequenies of the core long - period oscillations. while the spherical harmonic degree of the loading is larger than 10, the deformation and the gravitational perturbation in the core are very small, and the earth ' s deformation response is dominantly represented as the radial displacement in the elastic mantle
研究了地球在日月引潮力和表面負荷作用下的形變特徵，數值計算結果表明，在固體內核中的形變很小，由於在長周期核模本徵頻率附近的共振，液核中低階（ n 10 ）位移隨半徑的變化非常復雜，當負荷階數超過10時，地核中的形變和擾動位都很小，地球的響應主要表現為彈性地幔中的徑向位移，且隨深度增加急劇減弱，地表負荷love數與信號頻率的依賴關系很弱，給出了體潮love數計算的一種有效的近似處理方案。 -
The frequencies of translational actuation influence the stability of the tethered mass system. when the frequencies approach the natural frequency of the system, the period of energy exchange decreases and the amplitude of the pendulum increase. when the frequencies equal to the natural frequency of the system, resonance appears
變幅激勵的頻率對系統穩定性有較大影響，當變幅激勵頻率接近系統固有頻率時，系統面內外能量交換周期減小，擺幅增大;當變幅激勵頻率等於系統固有頻率時，系統面內外均出現共振現象。 -
The variation of wave - induced nearshore current fields and long period oscillation of water surface result in sediment transport, resonance of harbors, ship failures, diffusion of pollutants and difficult sea rescues, drawing scientific researchers " concern
由波浪產生的近岸流場的變化和水面的長周期振蕩，導致泥沙遷移，港口共振，船舶失事，污染擴散，海上救生困難，這些都已經引起了科研工作者的廣泛重視。 -
A new kind of physics experimental instrument of forced vibration and resonance is introduced, conducting research of the relationship between vibration period and to arms of prong
摘要介紹了新型音叉受迫振動與共振實驗儀。通過音叉雙臂與振動周期關系的研究，可以深入理解振動式液體密度傳感器的原理及其應用。 -
First point is about the problems that private enterprises meet in self - development, including structural conflict of their products, non - standard management, lack of talent and experience in the field of foreign trade, low technical content in products, and hardness to get needed information etc. many private enterprises adopt the behavior of pursuing benefit of short period as export with low price, serve with shoddy tort and so on, all those may disturb the export market and lash the normal trading order. the last one is the restriction factor of external operation environment. as the entrance threshold of foreign trade field is high, resonance like professional association does not play a deserved role, the export encouragement policy of government is unsuitable, the land resource has become increasingly intense, and problems still exist in formulating and implementing of p artial laws and regulations
首先是民營企業在自身發展中遇到的問題，包括結構性矛盾突出、經營管理不規范、外貿的人才和經驗匱乏、技術水平落後、難以獲得所需信息等，不僅制約了企業自身的發展，也對正常的外貿經營秩序造成了沖擊；其次是外部經營環境的制約因素，如外貿領域的準入門檻較高、行業協會等中介組織沒有發揮應有的作用、政府的出口鼓勵措施政策不當、土地資源日益緊張、部分法律法規的制訂和實施存在問題。 -
The numerical model based on vof method gives the bragg resonance phenomena and the resonant reflection coefficient agrees well with the result of physical experiment. the numerical simulation on the interaction between surface waves and the triangle / trapezium sandbars on the seabed also shows the bragg resonance and the resonant period matches the davies " prediction
應用vof方法所建立的數學模型，在與物理模型試驗相同條件下，數值模擬反映出的bragg共振現象及得到的最大反射系數與物理模型試驗結果吻合；對波浪與三角形或梯形沙壩地形相互作用的數值模擬也較好地反映出了bragg共振現象，共振周期與davies理論預測一致。
