本文在对蚁群算法和分类规则挖掘进行深入研究的基础上，提出了一种新的分类规则挖掘方法--基于蚁群算法的分类规则挖掘算法。

Compared with three familiar one-class methods,it is found that the SVDD has stronger classification ability and higher efficiency,which can distinguish the normal and abnormal screws ideally,and provides a new method for light-rail's screws fault diagnosis.

通过与常见的三种单值分类方法比较，表明SVDD分类器具有很好的分类效果和计算效率，能较好地区分正常螺杆和非正常螺杆，为轻轨锚固螺杆故障检测提供了新的诊断方法。

The results of separating distance among the woodland, cultivated crops and seasonal green vegetation are not exactly. The phenomenon of confusional classification is in evidence. The woodland, cultivated crops and brush need further classification.

在分类结果中，水体的分离效果最好，与其他覆被之间的Bhattacharya距离达到2.00，分类精度在90%以上，疏林地，农地，灌丛的分离效果不理想，混分现象明显，需进一步分类。

On the Harker diagram, there are general correlations between the oxides and SiO〓 of the Xiangshan complex, whereas the dioritic enclaves are not cosistent with the correlation trend of the complex. On the classification diagram of biotites, the biotites of the complex belong to ferribiotite, while the biotites of the diorite enclaves fall into the area of magnesio-biotite.

在哈克图解中，杂岩体全岩各氧化物与SiO〓之间总体上呈良好的线性关系，但闪长质包体却很不协调；在黑云母分类图解中，杂岩体中的黑云母均落在铁质黑云母分类区，而闪长质包体中的黑云母无一例外地落在镁质黑云母分类区。

The results showed that the deVelopment pattern of conidia of Arthrobotrys was holoblastic sympodial, and that of Monacrosporium and Dactylella was holoblastic.

此发育学的研究结果不赞成小属分类观，支持了大属分类观，为这类群菌的分类和以此为基础的属征修定提供了参考依据。

Numerical Taxonomy was inspirable and predictibe.

但由于数值分类等权对待分类特征，不能排除&趋同进化&和&平行进化&产生的形态相似，因此，分类单元的总体相似性并不能代表真正的系统发育关系。

Packet classification is a technique to match each incoming packet at a muter against a database of classifier and specify forwarding rules for the packets. The classifiers are a powerful and uniform way to implement new network services. The study on IP packet classification algorithm has practical significance and theory value.
