When he stopped working out, his six-pack stomach turned to flab.

一停止健身，他那六块腹肌就松弛了。

Firstly, we apply block AOR method to find the least square solution of minimal norm to the rank deficient linear systems where A is a complex m*n matrix with rank k.

首先，我们把求解线性方程组的块加速超松弛迭代法应用于求解亏秩线性方程组的最小范数最小二乘解，其中线性方程组的系数矩阵A是秩为k的m*n复矩阵。

In the solution of the Difichlet boundary problem ofLaplace equations, we provide an effective method for determining the spectral radiusand the best slack variable of block basic iterative methods. At the same time, wepresent the spectral radius and the best slack variable of basic iterative methods from thenine-point difference scheme.

在解决Laplace方程Dirichlet边值问题上，文章为确定块基本迭代方法的谱半径和SOR方法最优松弛因子提供了一个有效的方法，并推导了九点差分格式下的块基本迭代方法的谱半径和SOR方法最优松弛因子。

At last, a model is proposed to describe time effect of the rock interface friction resistance when viscous sliding and displacement softening occur,the relaxation model of friction resistance.

基于岩石块体摩擦滑动试验反映的特征规律，本文分析了岩块随时间滑动的界面阻抗机理，并建立粘滑位移弱化时反映滑动界面阻抗时间效应的模型公式阻抗松弛模型。

This method consists of two steps: first, the image is divided into numbers of nonoverlapping blocks and the GMRF parameters are computed for each of these blocks, then a clustering method is used to merge these blocks, a coarse segmentation and texture types of the image are obtained. Second, a deterministic relaxation neural network is constructed, the parameters of the model estimated from the first step are used as input data, through neural network computation, a fine segmentation is obtained.

提出一种基于高斯-马尔可夫随机场和神经网络的无监督纹理分割方法，方法分为两步：第一步先将图像分为不重叠的小块，在小块中计算GMRF参数，并将此参数和该块的均值、方差作为该块的特征向量，然后进行聚类，得到原图像的一个初始分割和图像中所包含的类别数；第二步构造一个决定性松弛的神经网络，将第一步得到的结果作为初始输入，经过神经网络计算，得到一个精确的分割结果。

Secondly, we discuss the semiconvergence of the block AOR method for solving singular linear systems with p-cyclic matrices.

其次，我们研究了求解系数矩阵为奇异p-循环矩阵的线性方程组的块加速超松弛迭代法的半收敛性。

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。
