During the post-processing, considering of the fusional continuance of time and content of commercial shots, we use a sliding window to refine the classification of shots in order to eliminate the wrong-classified shots.

在视频广告后期处理方面，考虑到视频广告段在时间和内容上的连续性和一致性，我们采用了滑动窗口值累计算法，对已经分类的镜头进行重新分类，从而消除错分类的镜头。

Scientific classification of soils is the basis of utilization and exploitation of soil resources. However, Soil Taxology, characterized by quantification, standardization and internationalization, is not popularized by far. So it is necessary to study its relationship with soil genesic classification and its application for agriculture and environment.

土壤的科学分类是土壤资源开发和利用的基础，土壤的系统分类以定量化、标准化和国际化为特点，但其大众化水平有待进一步提高，尚需加强与土壤发生分类的参比研究，并深化其在农业生产应用、土壤环境评价等方面的实践意义。

In order to further study the systematics and evolution of the family Hamamelidaceae, the five modern different classification systems of this family published by Harms (1930), Chang Hung-ta (1973,1979), Bogle et al.(1980), Endress (1989) and Li Jianhua (Li, 1997) are compared and discussed by the author based on the principle and method of study plant systematics.

为了进一步研究金缕梅科的系统与进化，作者详细介绍了该科的分类历史及各个分类系统；根据现代植物系统学研究的原理和方法，着重对金缕梅科的5个现代主要分类系统，Harms (1930)，张宏达(1973，1979)， Bogle et al。

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。

And then it combined binary tree with LS-WSVM, so that the LS-WSVM multi-class classification model based on binary tree was proposed. The model not only avoids the condition of blind classification and impartibility, but also improves classification speed and generalization ability.

然后，把二叉树结构和LS-WSVM相结合，提出了基于二叉树的LS-WSVM多类分类模型，不仅避免了盲目分类和不可分情况，而且提高了分类速度和泛化能力。

Prain, Trifolium repens Lam, Aeachynomene Mica L, Indigofera bungeana Steud.The same strains used in numerical taxonomy were analysed by BOXAIR-PCR fingerprinting. All tested strains were clustered into 47 groups at the similarity level of 50%. Compared with the result of numerical taxonomy, strains belonged to one phenon in numerical taxonomy always distributed into several BOXAIR-PCR groups, most of reference strains come from one recognized rhizobial species were not grouped together.

B(来源：dd9dAB94C论文网www.abclunwen.com)OXAIR-PCR指纹图谱的聚类结果显示：全部供试菌株在50％的相似性水平上分为47群，与数值分类的结果相比较，其分群的结果更分散，在数值分类80％相似性水平上位于同一表观群的供试未知菌株大多分布于几个综合的BOXAIR-PCR群内；另外在数值分类中来自同一个种的已知根瘤菌参比菌株几乎都聚在同一个表观群，而在BOXAIR-PCR分析中，已知参比根瘤菌的同一个种内的大部分菌株都单独成群。

A taxon or assemblage of taxa; e.g. the taxonomic group Insecta consists of all insects and the taxa in which they are classified.

一个分类单元或一组分类单元；例如昆虫纲这个分类群包含全部昆虫以及被列入的各个分类单元。

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。

In this experimental system, the main feature is that user can do some basal operation expediently using graphical interfaces, namely loading the existent data sets or creating new data sets, and choosing different kernel function to train the SVM classification, which can classify the given data correctly, it shows the result of classification and comparison of performance intuitionally.

在该实验系统中，最大的特点是用户可以通过图形界面方便地进行一些基本的操作，即装载已有的数据集，也可以创建新的数据集，并选择不同的核函数训练支持向量机分类器，能够对数据进行正确的分类，比较直观地显示了分类的结果。

Band differencing is feasible in water and irrigable field, but it couldnt monitor the changes of whole land use and its precision is the lowest. For the mufti-temporal composite method, it is difficult to choose the exact regions for change detection. Based on the previous accurate classification result, the post classification comparison method gets the best result compared with the other two methods, but also with the hand-on mistakes.

图像差值法对河流水面和水浇地的监测效果比较好，但对所有地类监测结果不令人满意，精度较低；多时相波段复合分类法中，变化土地类型训练区的确定较困难；分类后比较法是在前面土地信息准确提取的基础上进行的分析，精度较高，监测结果图也一目了然，是土地利用动态监测的一种有效方法，但它是在自动识别分类基础上进行的比较，传递了分类产生的误差。

In the negative and interrogative forms, of course, this is identical to the non-emphatic forms.

。但是，在否定句或疑问句里，这种带有"do"的方法表达的效果却没有什么强调的意思。

Go down on one's knees;kneel down

屈膝跪下。。。下跪祈祷
