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

This paper has studied the physiological and biochemical changes during the period of forming strong buds of tree peony, and expect to provide academic basis for extending its view value and economic benefit . The main results are as the following:1 Under the field condition, Characteristics of photosynthesis of tree peony are very regular. From before blooming to the prophase of abducting buds that after blooming ,that is April,May and June,the net photosynthetic rate of tree peony is higher than the other period .It indicates that this period is very important for accumulating photosynthetic products of tree peony . So, if we want to get quality flower of tree peony ,it is very important to strengthen the management of tree peony cultivation and to ensure provide the fertilizer and water.2 From the middle ten days of June, with the time elapsing and with the environment conditions worsening, the characteristics of photosynthesis of tree peony decline deeply. But it is different among different tree peony breeds. For example , cv. Wu Long Peng Sheng can also has higher net photosynthetic rate, it indicates that cv. Wu Long Peng Sheng is super than the other two tree peony breeds when adapting the environment conditions and cv. Wu Long Peng Sheng has wide prospect to extend .3 The main factors of effecting the characteristics of photosynthesis are stomatal factor and non-stomatal factor ,that is the ability of photosynthesis of leaf cells. Under the environment of high light intensity in midsummer, if overshadow tree peony properly, then it can slow the declining of chlorophyll content, and increase the net photosynthetic rate and benefit for the accumulating of photosynthetic products.4 The content of soluble sugar in the root of tree peony is the highest among different organs during the period of forming strong buds . According to analyse ,we believe that the soluble sugar will compose starch then, and provide the solid base of material for the growth and development next year. It provide us strong academic basis of adopting the method of cultivating root and protecting root under thefield environment conditions .In other words ,it will help to increase the health level of the whole plant of tree peony and will be beneficial to forming quality tree peony flower if we strengthen the management of root. 5 To tree peony, the endogenesis hormone is important for its growth and development .In the prophase ,that is about the blooming of tree peony and the mid-summer ,IAA and ZR contents are higher and GA content is lower and its changes are very little, and the content of ABA is decreasing . This indicates that IAA and ZR act the important promote function for growth and development of tree peony in this period, and the function of GA is not important. Bur in the period of anniversary senescence of tree peony , the content of IAA and ZR begin to decrease ,while the ABA content has a certain rebound .T
本研究对几个牡丹品种壮芽形成过程中的某些生理生化变化做了研究,以期了解牡丹生长发育过程中生理生化的变化规律,探讨大田栽培条件下提高牡丹花质量的栽培措施和管理技术,为提高牡丹的观赏价值和经济效益提供理论依据,结果如下:1 大田栽培条件下,牡丹光合特性在生长发育过程中表现出极强的规律性,牡丹各品种的光合速率从牡丹开花前,到牡丹花谢后的花芽诱导期前期(6月10日之前),也就是在4、5、6月份,各牡丹品种的净光合速率相对与其他时间都维持在比较高的水平,这说明,在这段时间,是牡丹光合产物积累的重要时期,因此,要保证得到高质量的牡丹花,在这段时间加强对牡丹的栽培管理,保证这个时期的肥水供应十分重要。2 从6月中旬后,随时间的推移,环境条件的恶化,牡丹的光合性能剧烈下降,但是不同牡丹品种间仍有差异,比如,乌龙捧盛仍可维持较高的光合水平,这说明了乌龙捧盛这个牡丹品种对于环境的适应性较之其他牡丹品种高,有着广泛的推广前景。3 影响牡丹光合性能的主要因子是气孔因素和非气孔因素即叶肉细胞的光合能力,在盛夏高温高光强的环境条件下,对牡丹进行适当遮荫,能缓解牡丹叶绿素水平的下降,适当提高Pn,有利于光合产物的积累。4 可溶性糖在牡丹各品种的壮芽形成过程中,根中可溶性糖的含量在牡丹各部位中始终维持最高水平,分析认为这些可溶性糖在根系中进一步合成淀粉等储藏性物质,为来年牡丹的生长提供雄厚的物质基础,这为我们在大田栽培条件下对牡丹采取养根护根的栽培措施提供了有力的理论依据,即在大田栽培条件下,加强对牡丹根系的管理,有助于提高牡丹整株的健壮程度,有益于形成高质量的牡丹花。5内源激素对牡丹的生长发育调节作用是十分明显的,在前期,即开花前后和盛夏,IAA和ZR含量维持在比较高的水平,GA含量低且变化不明显,ABA含量逐渐降低,说明了IAA和ZR对牡丹在这段时间内的生长发育起到重要的促进作用,GA的作用不是很明显,ABA可能在高温高光强下有明显的升高,也说明了ABA的确有一些促进作用,但是到了牡丹周年衰老期,IAA和ZR的含量开始下降,ABA含量却有了一定程度的反弹,说明了IAA和ZR的作用开始降低,ABA起到了促进衰老的作用

I began to run, but as I was still only half-awake, instead of going towards the stairs I went in the opposite direction. The smoke grew thicker and I could see flames all aroud. The floor became hot under my bare feet. I found an open door and ran into a room to get to the window, But befor I could reach it, one of my feet caught in something soft and I fell down. The thing I had fallen over felt like a bundle of clothes, and I picked it up to protect my face from the smoke and heat. Just then the floor gave way under me and I crashed to the floor gave way under me and I crashed to the floor below with pieces of burning wood all around me.
我开始跑起来,但仍是半睡半半醒样,不是朝楼梯跑去,而是向相反的方向走去,烟雾越来越浓,我找到一扇开着的门,朝房间的窗户冲去,但还没有到窗户边,我的脚就被一个软绵绵的东西绊住了,我摔倒了,将我绊倒的东西好象是一捆布,我正好把他捡起来遮住脸,用它挡住烟火和热气,脚底下的地板塌下去了,我和一块块燃烧着的木头一起掉到了下面的地板上。
