查询词典 Newton

Based on this Newton proposed the inertia definition and the law of inertia, but the inertin definition both does not have the physics significance and is the inaccurate personating analogy, also has the contradiction with Newton's second law, also does not propose what is the indispensable physical factor to maintain object movement.

牛顿在此基础上提出了惯性定义及惯性定律，但惯性定义既没有物理意义又是不确切的拟人化类比，又与牛顿第二定律有矛盾，也没有提出什么是维持物体运动不可缺少的物理因素。伽利略的结论经牛顿的惯性理论取代后就在很大程度上偏离了物理范畴。

It is proved that Newton iteration method is still quadratically convergent under a weak condition, and a new point is added to Newton s method , i.

本文讨论求解非线性方程的牛顿法，证明牛顿法在一个弱条件下仍保持局部二阶收敛性，给出牛顿法的一点改进，即一个不带导数的单参数的二阶收敛的迭代法，而且分别得到这两种迭代法的收敛因子，最后进行数值实验

Tne paper systemically discusses the object-image relations in the thin-lens imasery with Newton Formula and the relative graphs,and new and deeper theoretical otplanations are given. Thin-lens imasery Newton Formula,graph velation

These interference fringes were studied by Newton, and are called Newton's rings.

这些干涉环是由牛顿发现的，所以称之为牛顿环。

It is also a further improvement to the Newton-PCG algorithms. Moreover, by applying the Newton-PCG method and automatic differentiation, one new inexact method of tangent hyperbolas is proposed.

进一步将自动微分应用于牛顿-PCG型算法，构造了新算法，并从理论上证明了使用自动微分的牛顿-PCG型算法有非常显著的进一步的改进。

This paper considers nonlinear least squares problems,connecting new quasi-newton equations which has a higher-order curvature approximation with factorized quasi-newton method which is symmetric.

本文考虑非线性最小二乘问题，将具有更高的二阶曲率逼近的新拟牛顿方程和具有对称性的针对非线性最小二乘问题的分解方法结合起来。

And trust region type algorithm with memoryless technology not only satisfies new factorized quasi-Newton equation, but also saves much storage and algebraic operations than the original factorized quasi-Newton methods.we prove it posses the global convergence and the local superlinear convergence under some condition.

本文中利用无记忆技术产生的无记忆型信赖域算法不仅满足新分解牛顿方程，具有其所有的良好性质，而且比一般的分裂拟牛顿法节省存储空间，减少计算量。本文证明了在一定假设条件下该算法具有全局收敛性及局部超线性收敛性。

Simultaneously, the exports of ionization rate and nonionzed concentration are set up as a powerful tool for studying thoroughly the freeze-out effect. dN〓/dp and dN〓/dn are neglected in the linearized equation system of the iteration methods of Newton and Gummel, due to having lower 15 orders or more than dN〓/dn and dN〓/dp, thus the computing effort is cut down with no effect on precision. A new cut-off technique is adopted to accelerate the convergence speed, about twice reduced for Newton iteration method and six times or so for Gummel iteration method. The approximate formulae of Fermi-Dirac statistics are also put forward with simpler form and higher precision. 3. A term dependent on time is added to the electron and hole current succession equations respectively. It is only this model that conservation of charge in transient analysis and alternating small-signal analysis at low temperature can be kept by. 4. The performance of SE-PISCES is explained by the simulation example of PISCES-2B, diode.

研究了低温半导体器件模拟的数值方法：对载流子浓度进行了新的归一化；编制了不考虑掺杂所引进的内建电场时的电离率计算程序；由于低温杂质电离率随偏压状态而变化，为此编制了每次求解迭代时的电离浓度计算程序，并将其插入到求解迭代程序中；同时，设置了杂质电离率和未电离杂质浓度的出口点，为更深入地研究冻析效应提供了有力工具；在Newton迭代法和Gummel迭代法的线性化方程组中忽略了dN〓/dp、dN〓/dn，是因为它们比dN〓/dn、dN〓/dp低15个数量级以上，这样减小了计算量又不影响模拟精度；对Newton迭代法和Gummel迭代法采取了新的截断技术，提高了收敛速度，Newton法迭代法和两次左右，Gummel法减少六次左右；给出了表达式更简单而精度更高的Fermi-Dirac积分近似计算公式。

John Faulkner, of the Lick Observatory in California, has suggested an interpretation of these remarks which flies in the face of the Newton legend, but closely matches Newton's known character.

然而，在牛顿出版于1687年的具有划时代意义的论文集《原理》(也即《自然哲学的数学原理》)中，在讲述万有引力定律时，牛顿却只字不提胡克的帮助。
