A heuristic search strategy and a practical example are given.The result shows the consistent feature selection reduction method can eliminate the disaccords of the sample dataset,select the optimal feature variables,drop the dimension of the data and reduce the redundancy information effectively.

给出的启发式搜索策略和应用实例表明：一致化特征选择约简方法能有效消除分类数据集的不一致性，选择最优的特征变量、降低数据的维数、减少数据集中的冗余信息。

Based on analyzing the deficiency that traditional QFD which adopted exact digital scale cannot tackle the fuzzy problem effectively, according to linguistic variable expression style of HOQ input information and subjective evaluation way of HOQ constructing process, the comprehensive theoretic framework of fuzzy HOQ is founded. Surrounding each part of data fuzzing in building and analyzing process of HOQ and decision-making research of HOQ in the fuzzy environment, resolution methods are studied.

本文在分析传统质量功能配置方法采用精确数字标度无法有效处理模糊性问题的不足基础上，基于质量屋输入信息的语言变量表达形式和质量屋构建过程的主观评估方式，建立了完整的模糊质量屋理论框架，并围绕质量屋建立与分析中各部分的信息模糊化处理以及模糊环境下的质量屋决策研究解决方法。

Thus, this method is not restricted by the thickness and the layers of the laminates. And, it provides an valuable research method to the analysis of the interlaminated stress and failure of the laminates .

因此，该方法不受层合板厚度和层数的限制，它为层合板（特别是多层复合材料厚板）的层间应力和层间破坏分析提供了一种有效的研究工具。

Theoretical investigations suggested that the major bottleneck in narrowing down the confidence interval of QTL location is the limited number of informative meioses obtainable in most mapping populations of traditional methods.

理论研究表明，传统方法中作图群体有限的有效减数分裂数是进一步缩小QTL置信区间的一个瓶颈。

For the effective elastic moduli of composite materials with inclusions, the present theories are not satisfacto...

对于含夹杂复合材料的有效弹性模量，当夹杂的体积份数趋于0.4时，目前的理论不能给出令人满意的结果。

"This occurs despite significant adances in research describing brain abnormalities contributing to the deelopment and maintenance of alcoholism and aailability of seeral medications and psychotherapies that are effectie in reducing burden of these frequently occurring disorders," Bisaga said.

&尽管关于大脑异常在酒精中毒的发生发展中的作用的研究得到长足发展，并且有了数种能有效地控制这些频繁发作的功能障碍的新药和心理疗法，但对酗酒治疗的现状却仍没有任何改善。&Bisaga说。

Yield and ite relations to yiekd components , and its relation to ratooning ability were studied.

因此，提高头季稻的结实率和再生稻单位面积上的有效穗数是获得全年高产的重要保证。

The genetic analysis was carried out for 8 characters on 9 energy cane parents and their 20 combination crosses with the NCII mating design. The results showed that the inheritance of stalk biomass, brix weight, available stalk numbers and weight per stalk was subject to both additive gene effect and non-additive genes effect, but mainly controlled by non-additive genes. The inheritance of plant height, stalk diameter and brix was subject to both additive gene effect. The broad sense heritability (HB2) of stalk biomass and brix was over 50%, and those of brix weight were 33.7% at the seedling stage 54.4% at its ratooning stage, respectively , which means that the selection would be done better at the early stage in the sugarcane breeding program.

利用遗传交配设计对能源甘蔗9个亲本组配的20个组合、8个性状进行遗传分析，结果表明：地上部鲜重、锤重、丛有效茎数和丛重的遗传既受基因的加性效应也受基因的非加性效应所控制，但以非加性效应为主；株高、茎径和锤度的遗传主要是受基因的加性效应控制，地上部鲜重和锤度实生苗新植和宿根的H_B~2都在50％以上，而锤重的H_B~2分别为33.7％和54.4％，而且锤重和地上部鲜重母本gca方差都大于父本gca方差，说明能源甘蔗育种中母本选择的重要性。

Comparing with existing solutions, new method can utilize generators' speed signal measured by wide area measurement systems directly and detailed model and parameter of power system components were not needed. After sphering measurement-data, ICA with maximal negentropy criterion was carried out to obtain feature matrix. By this means high-dimension data of multi-machine perturbed trajectories were reduced to lower dimensions, and coherent generator groups were identified by pattern recognition consequently. Simulation results of 36-bus system with 8-generator and planning northwest China 750 kV power grid show that noise signals and bad data can be eliminated. This method is accurate in identifying coherent generator groups.

与现有方法相比，这种方法不需要获得系统元件模型和参数，而是直接球化广域测量系统(wide area measurement systems，WAMS)提供的发电机电角速度信号，再利用最大负熵准则进行独立分量分析得到特征矩阵，将高维数的多机受扰轨迹数据变换到低维空间，通过模式识别得到分群结果。8机36节点系统和西北750 kV电网规划系统算例表明，该方法能有效消除噪音和坏数据的影响，准确识别出同调机群。

When anchors were installed closely, says, Z/D=4, yielding soil around each anchor superposes highly, anchorage capacity of anchor groups does not increased linearly with number of anchors.

当地锚间距过於接近时(Z/D=4)，土壤降伏范围将产生高度重叠，增加地锚支数无法有效提高地锚之锚碇力。

With Death guitarist Schuldiner adopting vocal duties, the band made a major impact on the scene.

随着死亡的吉他手Schuldiner接受主唱的职务，乐队在现实中树立了重要的影响。

But he could still end up breakfasting on Swiss-government issue muesli because all six are accused of nicking around 45 million pounds they should have paid to FIFA.

不过他最后仍有可能沦为瑞士政府&议事餐桌&上的一道早餐，因为这所有六个人都被指控把本应支付给国际足联的大约4500万英镑骗了个精光。
