In other words, a relaxation scheme is equivalent to a fixed-point iteration on a preconditioned system.

换句话来说，原线性方程组的松弛迭代法等价于预处理之后的方程组的定点迭代法。

In this paper, we investigate the comparisons of asymptotic rates of iteration matrices of preconditioned and general iterative methods for solving non-singular linear systems.

本文讨论了解非奇异线性方程组的预条件方法与一般迭代法的比较理论。

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

Also the reciprocal theorem is invoked and analytical expressions of the Frechet derivatives are derived on the basis of NMM, and resultingly in each iteration the forward modeling is needed to be invoked only once.

为提高速度，采用前述的INMM方法，同时运用互易定理，并导出了基于NMM的Frechet导数解析表达式，这样，每次迭代只需一次正演。

When read returns an empty string, iteration is ended and is not resumable.

当 read返回一个空字符串时，迭代被结束并且不可被恢复。

In SART（Simultaneous Algebraic Reconstruction Technique）,there is no restrict to image space,so the image space's noise will increase after the definite number of iteration.

联合代数迭代方法对重建图像空间是无约束的，其迭代到一定次数后，图像空间的噪声会不断增加。

In this paper, we develop a new algorithm called the sequence subsets SART, which decrease the number of subsets after each iteration. Thus we not only accelerate convergence of the reconstructed image but also recover various frequency components of the reconstructed image in early iterative steps.

本文提出序列子集联合代数重建技术，在每次迭代后减少使用的子集个数，这样在加速图像收敛的同时恢复重建图像的各种频率元素。

However, since Jacob was alive in a previous iteration, his spirt is allowed to communicate with Ben to help Ben fulfill his destiny.

但是Jacob在以前的时间循环中是活着的，他的灵魂被允许和Ben交流，以此来帮助Ben完成使命。

Firstly, a homogeneous Harnack inequality as well as a maximum principle of nonhomogeneous subelliptic p-Laplace equations is proved by improving the classical Moser iteration method. The optimal estimate of m is also obtained through log |log| method.

首先改进经典的Moser迭代方法，证明了非齐次次椭圆p-Laplace方程的极大值原理和齐次Harnack不等式，并利用log |log|方法给出了不等式右端指数m的最佳上界估计。

Experiments are developed on different aspects, including the thickness of aluminum filter, choosing of the unattenuated data or not, characteristics of X-ray spectra, sensitivities to errors of attenuation data. Conclusion is that the iteration method is the best estimation technique.

以铝板作为滤波器材料，论文在滤波器厚度（包括最大厚度和最小厚度的选择）、未衰减数据的选取与舍弃、韧致辐射谱和包含特性辐射的光谱、对衰减误差的敏感性等多个层面进行仿真实验，比较分析了矩阵法和迭代法的优缺点，认为迭代法是进行光谱估计的最好方法。

Liapunov—Schmidt method is one of the most important method in the bifurcation theory.

Liapunov—Schmidt方法是分叉理论的最重要方法之一。

Be courteous -- even when people are most discourteous to you .

要有礼貌──即使当別人对你最不礼貌的时候。
