  1. A number of astronomical observations and experimental result were known to newton when he first tried to understand the dynamics of bodies.

    當牛頓首先試圖去了解天體的力學問題時，他已經知道了許多天文的觀測及實驗結果。
  2. According to the characteristic of the distribution network, based on thenewton - raphson method, used the object - oriented thought, bring forward an unite load node method for power flow calculation, and making a improvement of the node number method which is suitable for newton - raphson method, obtained a rapid convergence calculation method for power flow calculation

    根據配電網的特點，基於牛頓?拉夫遜法運用面向對象的思想，提出了負荷節點合併的潮流計算方法，並引入了改進的，適合於牛頓拉夫遜法的節點編號方案，得到了一個快速收斂的潮流演算法。
  3. Newton similarity number

    牛頓相似數
  4. We now give a number of applications of newton's second law to specific problems.

    現在我們舉例說明牛頓第二定律在實際問題中的應用。
  5. In the analysis, a cfst arch ( single tube ) is first divided into a finite number of straight beam elements. according to the virtual work principle and the modified newton - raphson iteration method the tangent stiffness matrix considering double nonlinear properties is established. with regard to the non - equilibrium forces, the material nonlinear property along the height of the section and the length of the element is considered and the computation accuracy is improved as a result

    本文首先將拱肋劃分為一系列的直梁單元，運用虛功原理和修正newton - raphan數值迭代演算法的基本原理準確推導了拱肋直梁單元的非線性切線剛度矩陣；在不平衡力方面考慮了沿截面高度和單元長度方向材料非線性的發展過程，提高了計算精度；再根據得到的切線剛度矩陣採用荷載增量步內修正newton - raphan迭代的增量迭代法進行了求解。
  6. Due to the convergence of cg method is strongly dependent on the condition number of the hessian, the inexact newton method with cg subiterations will be powerful if these cg subiterations are replaced by preconditioned cg subiterations with suitable preconditioner

    由於cg法的收斂狀態強烈的依賴于海色陣的條件數，所以用條件預優共軛梯度法（ pcg ）替代cg法會得到更好的效果。
  7. This papers gives simple iterative arithmetic of flow calculation. the precision of judgement and its value was changed, but the effect of iterative number and precision is roughly equivalent to fast newton iterative arithmetic

    文章提出了根據簡單牛頓迭代法來計算流量，改變精度判據並降低判據數數值，從實際迭代次數、運算精度來看效果與快速迭代法相當。
