Firstly, the sectional data from 27 companies in communications and transportation industry, which are listed before 1999, are linearly regressed. We find their capital structure and firm performance are irrelated significantly. Then the section data are quadricly regressed, but the result is also disillusionary, which indicates that the capital structure of listed companies has not the best range only with the sectional data from 1999 to 2003. Finally, in allusion to the problems in the securities market and illogicality of the capital structure, we put forward some methods to optimize the capital structure for listed companies from four facts.

文章首先对交通运输仓储行业1999年以前上市的27家公司的截面数据进行线性回归，发现在分析时段1999年至2003年，样本公司的净资产收益率和单位经济增加值与资产负债率之间线性不相关；然后文章又对该行业上市公司的截面数据进行二次函数回归，同样也没有得到令人满意的结果，这说明仅就1999年至2003年五年的截面数据而言，上市公司资本结构不存在最优区间；最后，文章对我国证券市场存在的问题以及该行业上市公司资本结构的不合理性提出了改进的设想，并从四个方面提出了优化我国上市公司资本结构的建议。

Usual, a lot of the time, wealways rush, no time to explain their feelings, when left alone toface a lot of time before the emergence of anxiety and regret, ifthat, of those buried in between the word and sentence Theintention is the life of poetry, it is better to say that, in fact,in a certain time the text of the poem is the heart., And here ismy sincere.

平常，很多的时候我们总是非常的匆忙，没有时间去解释自己的心情，等到独自必须要面对的时候才会涌现许多的不安与歉意，假如说，那些深藏在字与句之间的意向，是诗的生命，那么不如说，其实是在某个时段，是文者的诗心。，而在这里，便是我的真心。

The results indicate that the two-month average sea surface change charts were almost equal and isochroous, and the value of rise speed computed of tide gauge was bigger than that computed from satellite data.

结合福建尤溪流域公司20050615号洪水某时段实际降雨情况，详细介绍了使用Surfer（以Surfer8.0为例）软件具体绘制雨量等值线图的制图原理和步骤，并说明绘制雨量等值线图需要注意的几个问题。

Based on DEM data of different development periods of a indoor watershed model obtained from the integration of artificial simulated rainfall experiment and high accuracy digital photogrammetry technique, the fractal dimensions of topographic feature under different development periods of the indoor watershed model based on variation method were calculated and the relationships between watershed topographic feature fractal dimension and topographic factors such as watershed gully density as well as ground lacerative degree was discussed preliminarily.

以室内流域模型人工模拟降雨试验和高精度摄影测量获得的模型流域不同发育时段的数字高程模型数据为基础，采用变分法计算了流域地貌形态分形维数，并对分形维数与地貌因子沟谷密度和地面割裂度的关系进行初步探讨。

研究结果表明，生长季内海三棱藨草带大型底栖动物的多度和生物量整体呈上升趋势，但是月间存在一定波动变化，9月份多度最高，平均为1536ind／m^2，10月份生物量最高，平均为21.60g／m^2；不同月份优势类群组成、多度及生物量特征存在明显差异，瓣鳃类仅在部分时段表现出优势特征。

To avoid over-estimating capacity, this study divides production scheduling horizon into many small segmented buckets. To reflect the time-varying property of demands, this study decides initial production order by using "run out time of the inventory" proposed by Leachman.

为了反应需求率随时间改变的特性，将生产时期以避免高估产能的方式分割为数个分割时段，依据Leachman所提出的存货耗尽时间成本决定起始生产顺序。

METHODS: Fortyfive aged healthy crossbred dogs (15±7) kg were divided into 3 groups: tetramethlpyrazine group, verapamil group and control group. The operation was performed to ligate the near part of the LAD through left minimal thoracic incision to block 75% of the blood flow respectively.

将45只犬分为川芎嗪，维拉帕米和对照组3组，结扎LAD阻断血流75%，分别测定3组结扎前及结扎后不同时段的分泌型P选择素、内皮素1（ET1）、一氧化氮及心肌肌钙蛋白T的含量变化，Western blotting法检测心肌组织Pselecntin基因表达情况。

The operation was performed to ligate the near part of the LAD through left minimal thoracic incision to block 75% of the blood flow respectively. The expression changes of endothelium derived factors NO, ET1, sPselectin and CTnT before ligation and at different time points after ligation were detected and Pselectin gene of cardiac muscle was determined by Western blotting.
