在水库管理中,准确评估水质至关重要。然而,数据收集的不确定性和水质因子权重分配的局限性均会对评估结果产生影响。为了解决这一问题,以大伙房水库为研究对象,开发了一种新的水质综合评价方法,该方法结合了随机森林算法(RF)、优劣解距离法(TOPSIS)和蒙特卡洛模拟(MCS)。首先根据实测的月均水质数据,通过MCS生成了一组正态分布的数据集。然后,利用RF赋权为TOPSIS方法分配权重,并借助隶属函数对水质进行综合评价。通过计算分析,得出的结果与辽宁省的月度水环境质量状况报告提供的水质等级相符,这表明此方法能为大型水库的水质评估提供有力的技术支持。

THE MICROSTRUCTURAL BANDING IN THE CENTER OF HOT ROLLLNG STRIP

Acta Metallurgica Sinica(English Letters) 2005年第5期18卷 664-668页

作者： C.L. mo y. T. zhang D.Z. Li y. y. Li Institute of Metal Research The Chinese Academy of Sciences Shenyang 110016China Sheny.ng Ligong University Shenyang 110168 China

The microstructural banding in steels is often found in hot rolling strips, which play. a very.important role in mechanical properties. Much work has been done to investigate how the microstructural banding is formed during hot rolling. In the present study. the microstructure of hot rolling strips was examined in term of optical microscopy.and transmission electron microscopy. Electron probe microanaly.is was also used to decide the distribution of microchemical bands, by.this means, the phases in these strips were found to be ferrite and pearlite. The average distance between the carbon lamellas in pearlite is about 0.06-0.1μm. It is also shown that microstructural banding in hot rolled carbon steel was closely.related to the segregation of manganese and silicon into those bands. Based on the transformation kinetic, the simulated results pointed out that the thermody.amic stability.of austenite would increase with the increasing of Mn, which led to a decrease of ferrite growth rate. The effect of Mn on the decomposition of austenite is attributed to segregation of Mn atoms along the ferrite/austenite phase boundary.which causes a strong solute drag effect. The addition of Mn to steel decreases the activity.of austenite, thereby.it is beneficial to the formation of non-equilibrium phase, such as degenerate pearlite. The formation of banded structure on the hot rolled process was discussed.

FOR a long time, people pay.particular attention to the way.to decrease the charging current and improve the Faraday.current in the modern square wave voltammetry.(SWV), but the effects of random noise on analy.ical result are ignored. However, it is impossible to avoid the random noise absolutely.in the measuring process. Especially. when the concentration is low, the signal is affected seriously.by.the random noise and it is difficult to get a lower detection limit. So it is necessary.to know how to decrease the random noise in order to get a lower detection limit, while try.ng to find out how to decrease the charging current. A new sampling technique using the square wave potential scan is proposed to smooth the random noise and decrease the detection limit in SWV. The foundation of this new method comes from one of the laws of mathematical statistics; that is, the positive and negative probable errors in a group of detected data exist equally.and then the sum of all the errors is ze-
