查询词典 optimize

In this paper, finite-time thermodynamics is applied to optimize the intercooling pressure ratio and the heat conductance distribution of hot- and cold-side heat exchangers, intercooler and regenerator of a real closed intercooled regenerated Brayton cycle. Double-maximum efficiency is obtained by further optimizing the total pressure ratio. The effects of some important parameters on the optimal results are analyzed by detailed numerical examples.

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 research aimed to optimize the extraction technology of total flavone from Valeriana jatamansi Jones by ultrasonic method.

The results showed that the CV performance of PbO〓/PbSO〓 and PbSO〓/Pb powder microelectrode transformed from PbCO〓 under the optimize condition (the positive electrode was activated by asymmetric CV and asymmetric square wave current ways and the negative electrode using asymmetric CV) were better. Their electrode performances were as good as those made from leady oxide product by ball mill under the same conditions.

结果表明，将PbCO〓先制成粉末微电极，在30℃ 1.0mol/L H〓SO4〓溶液中经过化学转化为硫酸铅粉末微电极，以不对称信号活化(对PbO〓/PbSO〓电极，采用不对称循环伏安和不对称方波电流两种方法；对PbSO〓/Pb电极，采用不对称循环伏安法)得到电极的性能最好，正极活性物质的利用率高达89％，负极的达95％。
