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

The phenomena of function equilibrium between root system and canopy was observed.

本研究从植株整体的物理性质（源汇强度和韧皮部传输性质）出发，从更低的层次上模拟观察到了在环境水分条件发生变化时植株根冠间存在的功能平衡现象，并对此作出了机理性的解释，说明了当同化物的传输受维管束中压力势控制，而且韧皮部与所在器官的水势保持平衡状态时，根冠之间就会存在功能平衡关系，这说明了根冠间的功能平衡现象应该是维管植物适应环境变化过程中的一种普遍现象。

Starting from the real individual, Marx enters into the dimension of practice, and then he answers correctly to these two questions. For the real individual, the nature is not the abstract and isolated self-dependent nature, but the practical and humanized nature, namely the man and the nature are united. The production in which the real individual engaged is the material foundation on which the social consciousness relies, and with the change of social existence, the social consciousness changes as well; in other words, the social consciousness and the social existence are united.

马克思从"现实的个人"出发，进入生活世界的实践维度，对之作出了正确的回答：对于现实的个人而言，自然界不是抽象的、与人割裂的自在自然，而是现实的、与人结合的人化自然，也就是说，人与自然界是统一的；现实的个人所从事的生产劳动，是社会意识得以产生和存在的物质基础，社会意识随着社会存在的变化而变化，也就是说，社会意识与社会存在是统一的。

In the streets,sleepy-eyed people were moving quickly,heading towards their 26 .This was the beginning of another 27 day in New York City. 28 this day was to be different.

人们正在上班的路上，但上班的人并不是都坐办公室。heading towards的意思是"出发；动身"。

In my opinion, it is incorrect to definite chinese as a tool subject. From the angle of language nature, language is a complex systern of symbols used for human communications, it is obvious that language is closedly related to thought and language is an expression of culture, humanity and nation.

笔者认为，我们往往从语言的职能出发，界定语文的学科性质，然而当我们从语言的本质――语言是适应人们的交际需要而建立的一套复杂的符号系统――出发，将会发现，语言是与思维密切相联的，语言表达的内容具有思想性，语言及其表达的思想又具有文化性、人文性和民族性。
