An interesting observation is that the classical iterative methods can all be viewed as instances of an preconditioned system with different preconditioners.

值得注意的是，经典的求解线性方程组的迭代法也都能够看作是求解采用不同的因子预处理之后得到的线性方程组的迭代法。

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。

In this paper include: Successfully using iterative analysis method get some pulsive delay differential equations and sufficient condition of the existence,uniqueness and stablility of their solutions.

本文主要工作包括：利用迭代分析方法很成功地获得了某类脉冲和时滞微分方程解的存在性和唯一性，以及其解稳定的充分条件。

The basic iterative algorithm and the error spreading induced by the method were quantitively analyzed, and the certain relationship between the image spatial resolution and the image SNR was also presented.

在建立系统工作模型的基础上，对基本递推算法和由此引入的误差扩散效应进行了定量化分析，并初步给出图像信噪比和图像空间分辨率之间的量化关系。

Most agile methods share other iterative and incremental development methods' emphasis on building releasable software in short time periods.

绝大多数敏捷方法都沿用了迭代和增量式的开发方法，强调在短时间段内构建可以发布的软件。

Most agile methods share other iterative and incremental development methods' emphasis on building releasable software in short time periods.

我们需要注意，迭代开发并不是一个新的概念，也不是敏捷所特有的。RUP在十年前就在强调迭代开发了。

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。

Combined with the characteristic of the signal model in MC-CDMA systems, this semiblind method solves the problem of slow convergence by the initial channel estimation, estimates the scalar ambiguities by inserting some users' pilots and makes the algorithm complexity low by an iterative operation.

该方法结合MC-CDMA系统信号模型的特点，通过初始信道估计来解决收敛速度慢的问题；通过部分用户的导频符号以及预均衡技术来估计模糊因子；通过迭代算法来降低计算复杂度。

When the systems are singular, one requires only the semiconvergence of the iterative method.

然而当线性方程组奇异时，我们只能要求迭代法半收敛。

The split between the two groups can hardly be papered over.

这两个团体间的分歧难以掩饰。

This approach not only encourages a greater number of responses, but minimizes the likelihood of stale groupthink.

这种做法不仅鼓励了更多的反应，而且减少跟风的可能性。
