数据信息

The cost of this accident will be reduced to the lowest if we reduce the repair time and lessen the water cut range. As a result, analysis of pipe burst is one of the most important spatial analysis functions. Its effective realization consists of three aspects: the high quality data, the topological relation of data and the algorithm.

因此爆管关阀分析是供水管网地理信息系统中重要的空间分析功能之一，它的有效实现是由三个方面组成的：首先是数据录入时要生成高质量的数据，它是前提；其次是数据拓扑关系的建立，它是核心；最后是爆管分析的算法，它是关键。

As information technology development , data collection method plenty and advisability , there are more and more data about machinery fault.

摘 要：随着信息技术的发展，人们采集数据的手段日益丰富与高明，由此积累的机械设备故障数据日益膨胀，而且高维数据也日益成为主流。

These above problems, which are very important and valuable in agricultural crops area monitoring, are currently less researched. Hence, in this paper, seven types of common texture and five vegetation indices were respectively added into TM multispectral bands to classify using three different methods, which are Minimum Distance, Maximum Likelihood and Support Vector Machine, and analyze the effect on winter wheat identification accuracy by comparing the classification results. The contexture include Mean, Variance, Homogeneity, Contrast, Dissimilarity, Entropy, Variance, Angular Second Moment and Correlation, and the vegetation indices are RVI, SAVI, RDVI, NDWI and SLAVI.

为此，该文将平均值、方差、均一性、反差、相异性、熵、角二阶矩、灰度相关7种纹理信息以及比值植被指数、土壤调整植被指数、重归一化植被指数、植被液态水含量指数、有效叶面积植被指数5种植被指数信息分别加入到TM多光谱数据中，同时还进行了最佳波段选择，利用最小距离、最大似然和支持向量机3种方法进行分类提取小麦，研究了不同特征信息对小麦测量精度的影响。

The essence of exploitation geochemistry data processing is the identification of the geochemistry background and geochemical anomaly and the anomalistic data processing aims at finding out geochemical information on ore from abundance of original data which were got in reconnaissance.
