The experimental results show that this presented model obtains better results than that of the Naive B Bayesian, the Random forest, and the NNge predietion models when the high and low severity faults and the ungraded severity fault are distinguished.
实验结果表明,与基于朴素贝叶斯的预测模型、随机预测模型和NNge预测模型相比,本文提出的预测模型对于高严重程度故障、低严重程度故障以及未划分故障严重程度的情形均获得较好的预测效果。

Compared to the other carbon and nitrogen sources studied, sucrose and malt extract were found to be the suitable carbon/nitrogen sources. The decolorization efficiency of Cerrena unicolor Y5002 to orange G was similar at different orange G concentration below 500mg/L; however, alizarin red inhibited the decolorization reaction at the concentration of 400mg/L or above 400mg/L.
对一色齿毛菌Cerrena unicolor Y5002的液体培养脱色条件进行了研究,其最适碳源和氮源分别为蔗糖和麦芽浸粉;在不同橙黄G浓度下均获得较高的脱色率,因此浓度为500mg/L的橙黄G未对该菌的脱色能力产生抑制作用,而浓度为400mg/L茜素红则对其脱色作用产生明显抑制。

The thermodynamics quantities were calculated based on the first relaxation process. The results indicated that active enthalpy△H and active entropy △S all decreased with the increase of decrystallization extent. And, it was concluded that the relaxation process of untreated wood is for endothermic reaction and that of treated wood for exothermic reaction.
并通过计算获得了第一个松弛过程的各个热力学量,活化焓△H和活化熵△S都随着非晶化处理程度的增加而减小,未处理木材的松弛过程为吸热反应,而处理木材的松弛过程为放热反应。

The novel methods for the synthesis of Camptothecin intermediates were described as Friedlandle. Second, we synthsized the key compound—BI, and then made some improvements and innovations of the methods from the reference. The method of using more economically phenylaldehyde derivatives and phenylamine derivatives instead of o-aminobenzaldhyde was worked out.
然后成功合成重要的中间体BI,并且在参考原始文献的基础上作出了改进和创新,使用更便宜的苯甲醛衍生物和苯胺衍生物代替了邻氨基苯甲醛,合成了一系列未关B环的喜树碱中间体衍生物,并获得成功。

Looking forward to the future in faith and joy, the parish will request all parishioners to reregister their membership in March. A special team has been formed to explain to parishioners in details, asking for your cooperation.This census–registration involves a great deal of human and material resources. We wish that the technology of today would improve our efficiency for service, allowing parishioners to receive spiritual care faster and more easily.
充满信德﹑喜悦之情展望未来﹐二○○七年三月﹐本堂上下不分男女老幼﹐已登记或未登记成为本堂教友的﹐皆须重新登记﹐细节及方法﹐来日有专责小组人员向各位说明﹐到时务请各位教友通力合作﹔此项教友普查登记工作涉及多方面人力﹑物力的投资﹐期望透过今日的科技﹐提高我们的服务效率﹐使教友们能快速﹑便捷地获得灵性的服务。

However, in electric field computation, the BEM has not much unfould and most of them are limited in the conventional BEM. In the flow field computation, although some achievements have been gained in solving the constant and uncompressible fluid flow by using BEM, but to the inconstant, compressible, nonlinear, transonic flow, such as the flow in the arc quenching chamber in SF6 high voltage circuit breaker, no any report has been published up to now for the reason that the basic solution of this kind of flow has not been found.
目前,在电场计算领域所开展的工作相对较少,而且仅限于传统边界元方法的应用;在计算流体力学领域,近年来虽然一些学者应用边界元法,在解决定常、不可压缩等问题进行了相当深入的研究,获得了若干研究成果,但是对于像SF_6高压断路器灭弧室中存在的非定常、可压缩、非线性、跨音速、具有复杂而且变边界的气流场由于至今尚未找到基本解,而未见研究工作的报道。

However, the control performance of the PMSM drive is still influenced by uncertainties, which usually features parameter variations, external load disturbances, unmodelled and nonlinear dynamics. To achieve high-performance PMSM drive, which has great ability of adaptation and better performance against disturbances, advanced control schemes have to be developed to deal with these uncertainties.
然而,由于永磁同步电机驱动系统受电机参数变化、外部负载扰动、对象未建模和非线性动态等不确定性的影响,要获得高性能的永磁同步电机驱动系统,必须研究先进的控制策略以解决这些不确定性的影响,使系统具有较强的自适应能力和抗干扰能力。

At this stage the coral is still alive, and if the water cools, the coral can regain its zooxanthellae.[28] If the water does not cool within about a month, the coral will die of starvation. Australia experienced its warmest year on record in 2005. Abnormally high sea temperatures during the summer of 2005-2006 have caused massive coral bleaching in the Keppel Island group.
在这个阶段,珊瑚仍是活的,如果水温下降,珊瑚可以重新获得共生藻;如果约一个月内水温未下降,珊瑚将死于食物短缺。2005年是澳大利亚史上气温最高的一年,2005与2006年夏天异常的高温导致了凯珀尔岛群的珊瑚大量白化。

"The news media not doing as good a job as could be of informing readers of an important source of bias in medical research," lead author Michael Hochman, MD, a resident physician at the Cambridge Health Alliance and Harvard Medical School in Cambridge, Massachusetts, told Medscape Medical News.
主要研究者、哈佛医学院及剑桥医疗联盟住院医师Michael Hochman向Medscape Medical News表示,新闻媒体未善尽职责,他们应该告诉读者医学研究中偏见的重要来源;新闻报导通常以商品名而非俗名来报导药物,大部份的新闻机构没有正式的撰稿政策,规定所有有关医学研究的报导必须指出该研究获得哪些资金赞助,或者必须以俗名报导药物。
