指數阻尼量 的英文怎麼說
中文拼音 [zhǐshǔzǔníliáng]
指數阻尼量
英文
exponentially damping quantity-
Using the canonical variable representation ( x, p ), the light - damping oscillator is discussed by the corrected time - dependent perturbation methods of dirac, it is turned out that the energy levels have shift and breadth, and the wave function decaying with time exponentially
採用正則變數（ x ， p ）表象討論輕阻尼振子，並對量子力學含時微擾的狄拉克方法加以修改，得出量子能級有位移和寬度，以及波函數出現隨時間指數衰減的行為It is shown that vibration suppression efficiency of these kind of treatments depend much more on the viscoelastic layer thickness, material properties and the piezoelectric layer thickness. secondly, a linear quadratic regulator and output feedback are used to actively control vibration. it is shown that placing the active element on the opposite side of pcld or underneath pcld is capable of vibration suppression with lower control effort and more inherent damping
定義了主被動混合阻尼結構控制性能指標：被動抑振性能指標、主動抑振性能指標、控制能量指標和控制力性能指標；然後，基於狀態反饋最優控制律，根據定義的控制性能指標分析粘彈性阻尼層厚度、粘彈性阻尼材料參數、壓電作動層厚度對主被動混合阻尼結構振動控制性能的影響，得到了一些有價值的結論。Most of partial differential equation arising from physical or engineering science can be formulated into conservation form : it directly reflects conservation laws in natural sciences. from viewpoints of fluid dynamics, it can be obtained from the mass, momentum, energy conservation laws. because the form ( 0. 2. 1 ) has no other terms such as dispersion, diffusion ( caused by nonuniformity of some physical states ), reaction, memory, damping and relaxation etc, smoothness of solution of ( 0. 2. 1 ) may be loss as times goes on. even for the smooth inital data, solutions of ( 0. 2. 1 ) become discontinuous in a finite time
由於雙曲守恆律（ 0 . 1 . 1 ）沒有其它項，如色散（ dispersion ） ，擴散（ diffusion ） （某物理量分佈不均勻引起的輸運） ，反應（ reaction ） ，記憶（ memory ） ，阻尼（ damping ）及鬆弛（ relaxation ） （描述非平衡態）等，而僅有輸運或對流項（ convection ） （由於流體的流動引起的輸運）時，守恆律（ 0 . 1 . 1 ）的解失去光滑性（這里不特殊說明守恆律就指該意義下） ，甚至即使光滑的初始數據，解隨著時間的發展會變成不連續，這在物理上表現為激波的形成。We have deduced mathematical equations modeling its vibration and studied the stability of the semigroup associated with the equation system. we obtain the exponential stability under certain hypotheses of smoothness and structural condition of the coefficients of the system, applying the relaxation function decays exponentially. this result does not need the continuity of the damping coefficient at the interface
對于具有局部粘彈性阻尼的高維波方程的能量的指數衰減問題， liuetal . 51 }和riveraetal . 63分別對k一v型和boltzmann型的情形進行了研究，在假設了阻尼系數是光滑的並且附加了一些結構性條件的情形下，得到了指數穩定性的結果。分享友人
