For the tracking system, the means that can intellectively assist the fault diagnosis and maintenance is significant. Then we can avoid relying heavily on the experiences of the engineers and can reduce the probability of the event that engineers climb up to the antenna with heavy instruments when the faults turn out. For the data channel, to get the high-qualified remote sensing images, we need to get the quantitative data about how the factors influence the BER of Receiver .The data can help the design of receiver and the evaluation of the performance of a receiver. This thesis mainly contains those two parts.
对于跟踪系统,研究一套能辅助系统故障诊断及维护的智能手段是非常有意义的,这样系统维护时可以避免过多依赖技术人员的维护经验,特别是接收天线发生故障时携带仪器攀爬天线的情况;对于数据通道,面对高质量的遥感图像数据要求,我们需要得到影响接收机误码性能的各主要因素对应的量化数据,这些数据对于接收机的设计及性能评估是非常有帮助的。

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。
