查询词典 statistical data analysis

At the beginning of 2007, the data of COSCO Shanghai demonstrated that the oil-saving effect on "Yuan He","Teng He" and "Zhen He" vessels reached 22.8%, 6.5% and 8.6% respectively. Given the elements involved such as the improvement of hull surface finish, propeller surface finish, the working condition of the main engine after repair and the relatively small amount of data in the relatively short statistical period, the saving effect of PBCF might be "amplified" at present. Therefore, the Company will keep on tracing and analyzing the data.

在2007年初，根据上海远洋的提供的数据显示，&远河&、&腾河&和&珍河&轮安装PBCF后的节油效果达22.8%、6.5%和8.6%，这中间存在修船后船体表面光洁度、螺旋桨表面光洁度、主机工况的改善的因素，加之统计的周期相对较短，统计的数据相对不多，可能使目前PBCF的节能效果&放大&，因此，有待继续进行跟踪统计分析。

In order to reduce error of experimental data treatment, to strengthen accuracy of the result in conductivity determination of the dissociation constant of acetic acid, and also to further synthesis of experiment for training students' ability to treat data and to graph with computer, both Excel and calculator with statistical function have been utilized to perform a linear regression analysis of temperature-limiting molal conductivity of acetic acid solution.
