不中用了

Missirlis in article [1]. At the same time, a sufficient condition for convergence of the PSD method is given to be compared when the coefficient matrix A of the linear system Ax = b is a symmetric, positively defective matrix. In §3.2, an example is given to state that the range of our sufficient condition is wider than theorem 3.3 of article [1]. On the other hand, following a.n analogous approach of [14] and starting the functional relationshipwe have a perfect analysis for the PSD method to converge and optimum valves for the involved parameters under different conditions.Under the assumptions that A is a consistent ordered matrix with nonvanishing diagonal elements and the eigenvalues of the Jacobi matrix of A are real,we get necessary and sufficient conditions for the PSD method to convergence.The result is equal to theorem 1 of article [9].Under the same condition, we can see the optimal parameter and of corresponding spectral radius of thePSD method in [8]:(2)When A is a consistent ordered matrix with nonvanishing diagonal elements and the eigenvalues of the Jacobi matrix of A are imaginary or zero,we get necessary and sufficient conditions for the PSD method to convergence.In chapter 3, the optimal parameter and of corresponding spectral radius of the PSD method are given by table 3.3. Moreover, under the assumption 0

Missirlis在文献[1]中定理3.3的不准确，同时给出了当线性方程组Ax=b的系数矩阵A为对称正定阵时，PSD迭代法收敛的一个充分条件与之比较，并且在§2.3中用实例说明了对于一部分矩阵而言本文得到的充分条件广于[1]中定理3.3的充分条件；另一方面，按照文献[14]的方法，我们从PSD迭代法的特征值λ与其Jacobi迭代矩阵B的特征值μ的关系式：出发，在不同条件下对PSD迭代法的收敛性和最优参数以及最优谱半径进行了完整的分析：(1)在系数矩阵A为(1，1)相容次序矩阵且对角元全不为零，其Jacobi迭代矩阵B的特征值全为实数的条件下，给出了PSD迭代法收敛的充分必要条件，此结果与[9]中的定理1等价，此时最优参数及最优谱半径由[8]得：(2)第三章表3.3中给出了，当系数矩阵A为(1，1)相容次序矩阵且对角元全不为零，其Jacobi迭代矩阵B的特征值全为纯虚数或零时的PSD迭代法的收敛范围和最优参数，并且我们可以得到当0

So, bevelling around by Mullett's and the Signal House which they shortly reached, they proceeded perforce in the direction of Amiens street railway terminus, Mr Bloom being handicapped by the circumstance that one of the back buttons of his trousers had, to vary the timehonoured adage, gone the way of all buttons though, entering thoroughly into the spirit of the thing, he heroically made light of the mischance.

不久，他们来到牟累特食品店和信号所跟前，斜插过去，只得朝着阿缅斯街电车终点站走去。布卢姆先生裤子后面的一个钮扣，套用一句古谚，像所有的钮扣那样终于不中用啦。布卢姆先生尽管处在如此尴尬的境地，由于他透彻地理解事态的本质，就英勇地容忍了这种不便。

Just as Premier Wen said the sentence, as you live, to live well, not only Premier Wens expectations, even tens of thousands of brothers and sisters of our expectations, think about all those days and nights in Disaster areas the army for help, from the ruins of their hand to you to save 1.1 points out of the broken hand, the bloodshed, they moved the hands of tile brick shift has not stopped, they run the risk of aftershocks at any time to And the death race, is to allow more people to live, so that the good live, not only for ourselves, but also to all the people we love, good living, is our responsibility as well as your Obligations.

就像温总理说的那句话，你们既然活下来了，就要好好活，这不仅仅是温总理的期望，更是成千上万的手足兄弟对我们的期望，想一想那些不分昼夜在灾区求援的子弟兵，他们从废墟中用手一点一点把你们救了出来，手破了、流血了，可他们搬砖移瓦的手却一直没有停，他们冒着随时都有余震的危险来和死神赛跑，为的就是能让更多的人活下来，所以说，好好活下去，不只是为了我们自己，更是为了这一切爱我们的人，好好活，是我们的责任，也是你们的义务。
