Based on the 1950-1998 SST and NCEP/NCAR reanalysis data, the temporal/spatial variations of SSTA in the Western Pacific Warm Pool region have been analyzed in this paper by means of the methods of EOF and composite analysis. Results show that there are two main spatial patterns of the WP SSTA: one is uniform in the whole region, the other is meridionally anti-symmetric.

The main gluconeogenic precursor in kidney is thought to be lactate; however, less is emphasized enantiomerically. L-lactate is a glycolysis end-product, but D-lactate is formed after detoxification of methylglyoxal, which is the main source of advanced glycation end-products.

乳酸为肾脏糖质新生的主要来源，其含有一不对称碳，故具有D-、L-乳酸两种镜相异构物，而D-、L-乳酸两者之生成相当不同，L-乳酸是糖解作用之终产物，D-乳酸为体内一醣化终产物(advanced glycation end-products)─甲基乙二醛进行去毒化反应所生成，目前缺乏对乳酸镜像异构物与肾脏糖质新生间相关的探讨。

And two kinds of efficient iterative method, GMRES and Bi-CGSTAB, with different preconditioners are applied to solve the resulted nonsymmetrical systems of Fourier coefficients.

接著利用两种有效的迭代法(GMRES，BI-CGSTAB)来解离散后，傅利叶系数所形成非对称的线性系统并配合不同的preconditioner。

The general feature of deformation caused by the collision between two continents also reveals that, during the collision process, apart from a foreland basin and high mountains being formed, there is another compressive depression with an asymmetric structure developed on the side of the obducted plate, which is much easier to be formed when the dip angle of the collisional fracture zone is between 15° and 30° and is the deepest with a dip angle of 30°. This implies that the compressive depression is controlled by both subduction and obduction between two continents.

从大陆与大陆碰挂变形构造特征看，除发育前陆盆地－山脉系统外，在仰冲陆块一侧靠近造山带后缘还发育呈不对称结构的挤压性凹陷，当两个大陆板块碰撞断裂带倾角在15~30°时，该类型凹陷更容易形成，其中以30°倾角对应的凹陷最深，反映其形成可能是大陆碰撞过程中陆块之间相对俯冲和仰冲运动的综合结果。

The purpose of this thesis is to use finite element software ANSYS to analyze the mechanical behavior of thin-walled SUS304 stainless steel tubes with elliptic-notched subjected to curvature-controlled symmetric cyclic bending. The mechanical behavior contains the relationship among curvature, bending moment and ovalization. There are two kinds of the elliptic-notch.

本研究是以有限元素分析软体ANSYS 分析SUS304 不锈钢椭圆形凹槽薄壁圆管承受对称曲度循环弯曲负载下的力学行为，其中力学行为包含有曲度、弯矩及椭圆化的相互关系，而椭圆凹槽分为两种，一种为固定凹槽的深度，并改变凹槽的宽度；另一种为固定凹槽的宽度，并改变凹槽的深度。

Through condensing o-aminobenzoic acid, ethyl oxalyl chloride and ethylenediamine(or 1,2-propylenediamine), two new ligands N-benzoato-N′-(2- aminoethyl)oxamido(H3oxbe) and N-benzoato-N-(2-amino-2-methylethyl)oxamido(H3oxbt) have been synthesized. Their mononuclear complexes Na·1.5H2O and Na·1.5H2O have also been obtained.

2以邻氨基苯甲酸、草酸乙酯酰氯和乙二胺(或1，2-丙二胺)缩合制得了两种具有不对称草酰胺结构配体N-(2-苯甲酰基)-N&-(2-氨乙基)草酰胺(H3oxbe)和N-(2-苯甲酰基)-N&-(2-氨丙基)草酰胺(H3oxbt)，并得到了它们的单核配合物：Na·1.5H2O和Na·1.5H2O。
