Because of more monitoring classification and data type, too much data from the fishery monitoring,it is difficult to show results of data analysis intuitionally and roundly by groovy method of statistics and analysis...
由于渔业资源监测所获得的监测类别多,数据量大,数据类型较多,传统的统计分析方法,很难全面直观的将分析数据及结果呈现出来,同时由于渔业资源监测涉及到监测站点多、监测区域广,有的要跨越几个省市,这样数据难以与地理信息有机结合起来,传统的数据统计结果已不能适应渔业资源动态监测的需要。

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。

The most important part of an electronic cochlea system is the multiple-channel receiver-stimulator implemented in this thesis, which will be implanted into the mastoidal cavity nearby the cochlea. Data signals transmitted by an external speech processor are received through a tuned inductive coil. The power supply for the receiver-stimulator is derived from the rectified and filtered data signals. Meanwhile, the clock and the data envelope are extracted.
本文实现的多道(22根电极)电子耳蜗接收刺激器是人工电子耳蜗系统中的重要组成部分,它将直接被置入患者耳蜗附近的乳突骨腔中,通过电感耦合接收从体外语音处理器发射的数据信号,通过整流滤波为接收刺激器提供电源,同时提取时钟信号和数据包络[31]。

Directing at the data distortion caused by the fault of sensors, and considering the factors influencing the measurement of certain exhaust gas in an animal barn such as temporal, spatial and environmental parameters, neural network is introduced to data fusion so as to figure out the missed data due to the faults of this sensor measuring the value of this exhaust gas. By this method, total emission of nocuous gases from the barn is measured accurately, and the emission of exhaust gases beyond normal standard was controlled.

More experimental data of condensation heat transfer coefficient, especially ones obtained at some determined pressure of mixtures and concentration of noncondensable gases, are required in order to make a data bank. Therefore, the experiment is arranged for steam-air condensing on the outside of a horizontal smooth tube, and 405 data have been obtained for the pressure of the bulk mixture covering 0.1~0.5bar and the mass fraction of air 0.3%~10.0%.
