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.

采用海温资料和NCEP/NCAR 49a再分析的高度场、风场资料，利用EOF、合成分析方法，研究了夏季暖池SSTA的时空演变，结果显示：夏季暖池SSTA具有整体一致性分布和南北区域的反对称分布两种空间分布型。

When the spatial pattern is meridionally anti-symmetric, in the north-warm/south-cold years, an anticyclonic anomaly circulation exists over the warm pool at 850hPa, the easterly near 15°N and the westerly near the equator are greatly strengthened, while the center of the 200 hPa anticyclonic circulation moves to the East Asia, and the Hadley circulation is affected evidently, so the summer rainfall may be above normal in the middle and lower reaches of the Yangtze River, and vice versa.

当SSTA为南北反对称分布时，北暖南冷年850hPa暖池区上空为一反气旋偏差环流，15°N附近东风气流和赤道附近西风气流增强，200hPa反气旋偏差环流中心移到东亚大陆上空，长江中下游地区为上升气流，降水明显增多，华北地区为下沉气流，降水减少；冷异常年则相反。

The results indicated that there was an ecological succession of wetland plant communities and that the successive series is as follows: aquatic plant→helophytes→swampy prata→herbosa with the changes of habitat from aquatic to mesophytic. The horizonal distribution regularity of plant communities showed symmetric distribution at loop lake or banks of small stream and con centric distribution at depression. The vertical distribution regularity is as follows: aquatic vegetation→moor vegetation→swampy prata vegetation→subalpine meadow subalpine shrub from the center of lake to the hilltop.

结果表明，随着湿地水分由多到少的变化，植物群落类型发生相应的生态演替，其演替序列为水生植被→沼生植被→沼泽化草甸植被→草甸植被，且在水平方向呈对列式和同心圆式分布；从湖心至丘顶的垂直分布规律表现为水生植被→沼泽植被→沼泽化草甸→亚高山草甸→亚高山灌丛。

From the study on the mathematical properties of the matrix, we propose a general theory of odd/even modal decomposition of symmetric multiconductor transmission line equations.

通过对镜像对称矩阵数学性质的研究，我们提出了对称传输线方程奇偶模分解的一般理论。

Splitting of the nondegenerate symmetric deformation vibration is also interpreted by a vibration-vibration coupling mechanism which agrees well with the measured energy difference.

关联场理论计算结果给出分裂双峰的能量间距为19cm〓，与实验结果的27cm〓很好地吻和。

Moreover, we examine how the agency cost between managers and liquid shareholders is affected by nonliquid shares and stateowned shares, which we believed to exist only in Chinese Market. Through the same method of event study, we find a symmetric effect regardless of the proportion of nonliquid shares, and this shows that the proportion of nonliquid shares is not a factor of conflicts between managers and liquid shareholders. As for the sub-sample with stateowned shares, there is a larger positive price impact for firms with high proportion of stateowned shares, which tells us that the stateowned shares do raise the problem of "absence of the owner", and it is a part of agency cost in China.

我们进一步检验了国内特殊存在的非流通股以及国有股对于管理层与流通股东之间代理成本的影响，通过同样的事件研究方法对上述样本进行市场宣告反应检验，结果发现非流通股比例不同的公司其市场反应并无显著差异，说明非流通股的存在对管理层与流通股东之间的代理问题没有影响；而国有股比例不同的公司其市场宣告反应存在显著差异，这说明国有股产生的&所有者缺位&问题成为国内代理成本的一部分，并确实影响了现金股利的发放。

A numerical method for the T-matrix approach of light scattering by randomly oriented arid axially symmetric nonspherical particles performed in PC machine is presented first.

首先介绍了无规取向轴对称非球形粒子光散射的T-矩阵数值方法。

The results show that the heterostructure photonic crystal can extend remarkably the photonic bandgap compared with the periodic structure;a defect is inserted into the heterostructure photonic crystal,the nontransmission band is wider than that of the symmetric structure without heterostructures,(1H1L)_m(1H)_n(1L1H)_m.

结果表明，与周期结构相比异质结构光子晶体可以显著地拓宽光子晶体的光子带隙；在该文提出的结构中引入缺陷，与(1H1L)m(1H)n(1L1H)m光子晶体相比，产生缺陷模式光子带隙范围明显拓宽，适当调整缺陷层的数目、位置和厚度可得到多通道滤波；并研究了实际操作中随机误差带来的影响，随无序度的增大，其带宽基本不变。

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.
