查询词典 entropy

This paper introduced the concept of information entropy for analyzing the influence of DEM resolution on topographic characteristics(slope,upslope area per unit contour length and topographic index) calculation.

本文以褒河流域为例，引入信息熵的概念量化分析了 DEM分辨率对地形特征(坡度、单宽上坡集水面积和地形指数)计算的影响，发现随着 DEM分辨率的降低，计算得到的坡度值偏小，单宽上坡集水面积值偏大，从而导致地形指数计算值偏大。

The experimental results show the validness of the mechanism analyses.2. According to the generation mechanism of the leak acoustic signal, the characteristics of the leak acoustic signal are investigated. The auto correlation technology is adopted to descript the leak signal characteristics due to the ability to analyze the coherence of time series. A new procedure to identify the leak acoustic signal from the disturbed noises is proposed based on the conjunction of correlation and approximate entropy algorithm.3. The principle and application in leak location of the correlation and the adaptive filter techniques are introduced. The problems of the traditional leak location methods are analyzed.4. In order to establish the leak detection signal model, the leak acoustic propagation characteristics are investigated experimentally.

从泄漏声产生机理出发，分析了管道泄漏处湍流拟序结构与空泡间相互作用的机理，认为在该机理作用下，泄漏声信号产生过程具有&不可重复&的特征；由于相关函数具有分析时间序列拟序结构的能力，且近似熵从统计的角度区别时间过程的复杂性，因此，提出将信号相关分析和近似熵理论相结合的方法，提取泄漏声信号&不可重复&的特征，辨识管道泄漏故障发生；在实际检测现场，由于各种管内和管外固定声源噪声(如阀门噪声、工地施工噪声等)常导致泄漏误判和漏点定位错误，重点分析了管内固定噪声源的产生机理和特征，为复杂干扰环境下的泄漏辨识提供理论支持。

The entire political practice of the present regime, as I have tried to outline it here step by step, confirms that those concepts which were always crucial for its program-order, calm, consolidation,"guiding the nation out of its crisis,""halting disruption,""assuaging hot tempers" and so on-have finally acquired the same lethal(causing or sufficient to cause death)meaning that they have for every regime committed to entropy.

这种现存制度的全部政治实践，像我在这里逐步描绘的，进一步证实了对它的纲领来说总是关键性的概念——秩序、安定、稳固，&带领民族走出危机&&停止分裂&&缓和激烈的情绪&等等——最终得到每一个提交*(这种译法殊为怪异，可译为&委身&)给熵的制度所具有的同样致命的意义。

The weights are calculated by information entropy indicating the availing value of data, and the problem of weight allocation is solved.

用信息熵所反映数据本身的效用值计算指标的权重，避免了权重分配困难的问题。

This article has selected three methods of weight calculation: single item index method of weight; synthesis index method of weight; entropy method of weight After the expatiation of theories and means, we analyzed example by using the fuzzy comprehensive evaluation method baaed on these three kinds of methods of weight calculation, and then came to the conclusion through contrast: the first method is very sensitive to superscale; the other two methods, which consider more factors' influence, can generally reflect the real status of water quality, and the results are consistent and relatively better.

现选取了单项评价指标权重法、综合权重法以及熵权法三种不同的权重计算法，分别详述了其计算原理和方法，并在基于这三种权重计算法的基础上采用模糊综合评判法对实例进行分析，最终通过对比得出结论：基于单项评价指标权重法的模糊综合评判法对单个超标因子比较敏感；基于综合权重法和熵权法的模糊综合评判法则综合考虑了各个指标因子对评价结果的影响，能够较全面的反映水质的实际情况，评价结果几乎一致，且相对较好。
