本文讨论对流扩散方程：的相似源型解。由于方程具有对流项且初始值为Dirac测度，特别当m＞1时方程在{u＝0}处退化，给求解造成实质的困难。

Directed HD distance is taken as the similarity measuring of template matching and effectively it can reduce the matching calculation amount; the immune genetic algorithm has powerful robust and parallel searching.

部分HD距离作为模板匹配的相似性测度，可有效减少匹配计算量；免疫遗传算法具有较强的鲁棒性和强大的并行搜索能力。

After the human is detected and extracted, we then track body parts of the human by using appearances of these parts as the features and using particle filters as the tracking kernel. In the particle filter, we adopt color histograms as the appearance features and use a specific histogram mapping to enhance the discriminability between different objects. To form a robust tracker that can distinguish target objects from background objects that have color distribution similar to those of target objects, we calculate the target similarity from both the target object model and the background model.

当人体被侦测及切割出来后，接著我们使用人体部位外观当作特徵并且使用粒子滤波器作为核心来追踪此人体，我们采等化之颜色统计表当作粒子滤波器中使用的外观特徵以强化不同物体的鉴别率，为了建立可稳健区别目标物及背景物体的追踪器，我们同时使用目标的模型和背景模型来计算目标物的相似度，为了对抗背景及目标物的外观变化，背景模型及目标物模型都是可适应变化的。

The similarity and difference between the composites of compact detergent and the composites of laundry detergent tablet were analyzed and compared.The factors,which affect the disintegration and dissolution of the detergent tablet,such as the types of surfactants and builders ,particle size,pressure,binders,hydrotrope and disintegrant were especially discussed.

分析对比了片状洗涤剂和浓缩粉在配方上的相同点和主要区别，特别对影响片状洗涤剂成型和溶解速度的主要因素，如表面活性剂和助剂原料、造粒方式和粒度大小、压片强度、黏合剂、水助溶剂及崩解剂种类等技术特点进行了讨论。

A method of similarity measurement is discussed based on the improvement of quadric form distance function.

在改进加权二次型相似性度量方法的基础上，提出了相应的主色多特征相似性度量方法。

Methods Jaccard coefficent is employed to measure the similarity of individuals, and the distance matrix is constructed.

采用 Jaccard系数进行样品间的相似性度量，构建非欧几里德距离矩阵，在 SAS数据步过程中完成上述计算，并生成分析数据集，通过调用 Cluster过程对资料进行聚类分析。

Then the similarity between them is calculated based on this distance matrix. To validate this retrieval approach, we test it on a database containing about four hundreds motion clips which can be divided into various kinds of human movements. The experimental results demonstrate the effectiveness of our approach.

实验结果表明，与现有大多数基于内容的三维人体运动数据检索方法相比，该方法能够取得更好的时间效率且不依赖于任何预先设定的参数，相对于现有基于关键帧的运动检索技术而言，其能够获得更好的检索效果。

When there is a high degree of similarity exists in the merchandise, brand may be the only resort to distinguish oneself from competitors.

当商品存在高度同质性时，品牌可能是唯一能够与其他竞争者有所区别的方法。

Sequences analysis revealsthat these 54 strains have as high as a 99% similarity in 16S rRNA gene level. Allthese 54 strains could be classified into six subgroups according to six differentregions on full-length 16S rRNA gene. Even if the regional differences are not evidentto distinguish B. thuringiensis from B. cereus, however the data of the 16S rRNA genesequences will serve to broaden the database for Bacillus, and provide someinformation for the classification of genus of Bacillus. Additionally, seven B.

本研究利用通用引物，对54株苏云金芽胞杆菌和蜡状芽胞杆菌的16S rRNA基因进行测序，并对所得到的序列进行简单的分析，发现苏云金芽胞杆菌和蜡状芽胞杆菌的16S rRNA基因的相似性很大，大约为99％，在其全长含有6个区域的不同，根据这6个区域将Bt和Bc分成6个亚群，而Bt和Bc在不同亚群之间交替存在，说明16S rRNA基因上的差异不足以区分Bt和Bc。

However, it is difficult to distinguish them because of similarity of morphology.
