Our results improve the former results. For periodic Jacobi matrix, some new spectral properties of periodic Jacobi matrix are given by studying the relationship of the eigenvalues of periodic Jacobi matrix and its n—1 principal submatrix. Applying these spectral properties, we present a necessary and sufficient condition for the solvability of an inverse problem of periodic Jacobi matrices and discuss the number and the relationship of its solutions. Furthermore, we propose a new algorithm to construct its solution and compare it with the former algorithms. As this inverse problem of periodic Jacobi matrix usually has multiple solutions as many other eigenvalue inverse problems, we study the uniqueness of this problem. And a necessary and sufficient condition is given to ensure its uniqueness, under which an algorithm is presented and the stability analysis is also given. Finally, we put forward a new inverse problem for periodic Jacobi matrix which has not been solved.

As the beginning of this thesis, the important meanings of sea ice to global climate change and ocean engineering in polar and subpolar sea regions are explained firstly. Then, it is pointed out that sea ice numerical modelling, as a powerful tool of sea ice research, is limited by the precision of parameters within models instead of itself so far. It is meaningful to study the important parameters of sea ice dynamics by means of the rapidly developing digital imaging techniques so as to provide better input parameters needed in numerical models.

Results Analysis of the expression of proteins of JAK2 in leukemic blasts, there was no detectable constitutive expression of phosphorylated JAK2 in all the AML samples analyzed; Furthermore, we could detect a constitutive activation of STAT 3 by immunoprecipitation of the targeted protein in primary leukemic blasts from 3 of 11 AML patients without any cytokine treatment; Pretreatment clinical characteristics, and treatment regimens did not differ significantly between patients with and without constitutive STAT3 activity, there was not significant relation between the constitutive activation of STAT3 and the FAB subvariety and chromosome karyotype; However, the 3 patients with constitutive STAT3 activity seemed to have adverse treatment outcome, one did not show remission, the other two patients relapsed shortly after remission; Consistent with the above-mentioned result, leukemic blasts from the 3 samples with constitutive expression of STAT3 showed higher percentage of spontaneous apoptosis and S-phase cells.

We have no common name for a mime of Sophron or Xenarchus and a Socratic Conversation; and we should still be without one even if the imitation in the two instances were in trimeters or elegiacs or some other kind of verse--though it is the way with people to tack on 'poet' to the name of a metre, and talk of elegiac-poets and epic-poets, thinking that they call them poets not by reason of the imitative nature of their work, but indiscriminately by reason of the metre they write in.

索夫农 、森那库斯和苏格拉底式的对话采用的模仿没有一个公共的名称；三音步诗、挽歌体或其他类型的诗的模仿也没有——人们把&诗人&这一名词和格律名称结合到一起，称之为挽歌体诗人或者史诗诗人，他们被称为诗人，似乎只是因为遵守格律写作，而非他们作品的模仿本质。
