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

Consistent with the rift of the Eurasian plate and the northwestward spread of the Pacific plate, the stress field from large scale of mantle convection displays a skeleton of dumbbell shaped with sinistral compresso-shear at the north, dextral compresso-shear at the south and slip in the middle. Energy converge strong at the south is attributed to the northward movement of the Indian ocean.

Beginning with the Nazi eroticization of the bodily ideal, Linke moves across the 1945 threshold to explain how the new Germany organized its understanding of the body: public nudism the revival of the cult of the body the attempt to de-eroticize white nakedness Linke also examines the the 'feminization' of the 'guest' labourers; foreign workers needed during the reconstruction boom and then regarded as unwelcome aliens and the ways in which today's German left and militant right converge.

随着身体的理想，在1945年的门槛林克纳粹eroticization举动解释如何开始新的德国组织的理解身体：公众裸体主义的身体，以德企图eroticize白色裸体林克也邪教复兴检查是的'女性化'客人'劳动者；在重建繁荣需要外国劳工，然后为不受欢迎的外国人，以及如何把在今天的德国左翼激进的权利和衔接。
