牛頓勢
英文
newton potential-
Are these trends not comparable with newton's law of inertia ?
這些趨勢難道和牛頓的慣性定律不是很相仿嗎？Abstract : since the multiple failures situation is not uncommon in the clinical medicine, we explore the use of proportional odds model to the multivariate interval - censored data. the approach is based on the conditional logistic regression, which prevents the complications in the existence of nuisance parameters. the estimation of parameters is obtained by the newton - raphson algorithm. the sandwith estimator for the covariance is made according to the situation where there is correlation in the score statistic. simulations are also presented to assess the accuracy of the procedure
文摘:探索比例優勢模型在臨床醫學中常見的多結局區間截斷數據中的應用.用條件的邏輯回歸方法避免討厭參數的估計，用牛頓-拉普森演算法估計回歸系數，用"夾心方差"估計量作為參數方差的估計.通過隨機模型檢驗模型應用的有效性Using newton mechanics method discussion about conservation condition of mechanical energy, we get the conservation under zero rotation and implict time in potential formula
摘要本文用牛頓力學方法分析了機械能守恆的條件，指出只有力滿足旋度（方程式略）的條件，而且在勢能的表達式中不顯含時間，機械能才守恆。An interior - point potential reduction algorithm is established to solve general nonlinear programming by a combination of the classical damped newton method and the primal - dual interior - point potential reduction method for linear programming
摘要結合經典阻尼牛頓方法和線性規劃內點勢減方法建立了一個求解一般非線性規劃問題的內點勢減演算法。The many - body potential ( eam potential ) is applied to describe the interaction of the atoms in the code. the parameters, such as position, velocity etc, are obtained by solving the newton equations of motion
它採用多體勢（嵌入原子勢）描述原子間的相互作用，通過求解牛頓運動方程來獲得原子的位置、速度等物理參量。The study state of art and development trend of structural damage identification research is simply summarized in this paper. hilbert - huang transform ( hht ) is applied to the damage identification and intrinsic frequency confirmation of time - variable structures. furthermore, a kind of inverse calculation is presented to calculate structural stiffness. this method can solve three main problems : the time that damage occurred, the location and the degree of damage
本文簡要總結了結構損傷識別領域的研究現狀和趨勢，圍繞損傷引起固有頻率變化這個特徵，將希爾伯特?黃變換（ hht ）應用於時變結構的損傷識別和損傷前後固有頻率確定上，並結合牛頓迭代法，對結構剛度進行反演計算，從而解決結構損傷識別領域所關注的三個主要問題:損傷發生時間、損傷位置以及損傷的程度。The full potential equation is solved by the time - accurate approximate factorization algorithm and internal newton iterations, and the euler equation by the finite - volume resolution scheme and dual - time stepping
