It's pointed out that soft sensor will play more important role in field bus network control system. According to this, a crude solution was addressed. At last, we point out that soft sensor technology must used to build an information warehouse for the whole enterprise, combined with data fusion, data warehouse, data rectification and other related technologies. The main contributions of this dissertation are as follows: The background, requirement, and application situation of soft sensors are expounded, the theories, methods and skills of soft sensing technology are analyzed, and the fruits and problems in current soft sensor technologies are summarized. Some new methods of soft sensor is proposed: A principal component analysis-based secondary variable selection method are proposed; A new conception which modeling data should have gross error detection is addressed, and then a cluster analysis-based modeling data gross error detection method is given.

本文的主要贡献有:对软测量技术根据实践的要求进行了一定的理论研究,针对具体问题提出了新的方法:讨论了辅助变量选择问题,研究了基于主元分析的辅助变量选择方法,该方法克服了传统方法只能利用数学模型产生的仿真数据进行最优辅助变量选择的缺点,可以根据历史数据进行辅助变量选择;提出了建模数据显著误差侦破的概念,指出传统的显著误差侦破研究的是已知过程数学模型的情况,而建模时数学模型是未知的,但是直接来自现场的数据并不能保证不含显著误差,并用基于聚类分析的方法解决了该问题,该方法利用聚类分析原理,直接面对过程数据,不需以过程模型为基础,在此基础上给出了软测量建模过程中样本数据的处理方法。

By applying psychological measurement methods, the author compared volition quality between short track speed skaters with difference sports performances and genders in order to gain an insight into if there is a dif-ference in volition quality between them, and revealed the following findings: in terms of objective clearness male skaters at international master sportsman level are superior to male skaters at national master sportsman level, but in terms of renitency male skaters at national master sportsman level are superior to male skaters at international mas-ter sportsman level; female skaters at national master sportsman level are superior to level 1 female skaters in terms of renitency, determination, confidence and total score, and differences between them are significant; furthermore, by comparing volition quality between male and female skaters, the author found that in terms of toughness male skaters are superior to female skaters, and the difference is significant, but in terms of other 5 factors and total score, differences between them are not significant.

摘 要:采用心理测量法,从不同运动水平、不同性别短道速滑运动员意志品质的比较入手,了解其意志品质是否存在差别。结果表明:男子国际健将运动员在目标清晰维度上好于男子国家健将级运动员,但在顽强性维度上,国家健将级运动员好于国际健将级运动员;女子国家健将级运动员在顽强性、果断性、自信心3个维度和总分上均好于女子一级运动员,两者差异具有显著性;此外,比较男、女运动员之间的意志品质,发现男运动员在坚韧性维度上好于女运动员,差异显著,但在其他5个维度及总分上,两者差别不具有显著性意义。

There were no significant differences in contents of quercetin, isoquercitrin and kaempferol in the fronds, and also no significant differences in contents of rutin, quercetin, kaempferol and total flavonoids in the roots of the three plants studied under the same As treatment.

结果表明:在相同As浓度处理条件下,叶片中槲皮素、异槲皮甙和山奈酚的含量不存在显著差;根部芸香苷、槲皮素、山奈酚和总黄酮含量也不存在显著差异。

Results: Compared with IR group , XSOL could significantly decrease the cerebral water content, the cerebral index, the brain vascular permeability in rats of acute incomplete brain ischemia-reperfusion (P.01,P.05). Cerebral tissue morphology showed that neuronic damage of rats subjected to acute incomplete brain ischemia-reperfusion was ameliorated following administration of XSOL (2.4, 9.6g/kg). Compared with IR group , XSOL could significantly decrease the content of MDA and NO in brain tissue(P.01,P.05)and increase SOD,GSH-px activity. The levels of cerebral Glu,Asp were cut down(P.01,P.05). Conclusion: XSOL shows protective effects on cerebral ischemia-reperfusion.
