Two new data structures TOPSIS-Tree and RELIS are devised to maintain potential significant itemsets and mined results, respectively. Moreover, three optimal strategies are exploited to reduce time and space consumption of the algorithms:(1) pruning impotent nodes in the newest basic window whenever a sliding window updates,(2) promoting support threshold during mining process dynamically, and (3) adjusting pruning threshold adaptively and heuristically.

设计概要结构TOPSIS-Tree和RELIS分别存储和记录流数据的摘要信息和当前滑动窗口的挖掘结果，并设计了三种优化策略用以提高算法的时空效率：(1)滑动窗口更新时剪枝最新基本窗口的无功节点；(2)挖掘过程中动态提升支持度阈值；(3)启发式自适应调整剪枝阈值。

Dan Kiley has for a long time designed on the basis of a formal organization of his landscape, classic in the sense that its foundations include the traditions of both Islam and the West. His are ordered landscapes, normally with a clear geometric plan structure which nevertheless reads excitingly in three dimensions.

丹凯立长期以来都以形式组构为基础进行地景设计，呈现出伊斯兰与西方传统所具有的古典感；他的作品是秩序性的地景，通常有清楚的平面几何架构，然而在三向度中却又十分引人。

The most frequently grazed three kinds of plants were Artemisia frigida, Cleistogenes songorica and Kochia prostrate.

结果表明：1。五趾跳鼠是以植物性食物为主的杂食性啮齿动物，对植物性食物具有较强的择食性，放牧制度对该特性影响不显著；五趾跳鼠在短花针茅草原连续放牧区和轮牧区内的植物性食物组成相似度为0.71~0.88，采食频率最高的三种植物是冷篙、无芒隐子草和木地肤。2。

Results Maxillary first and second molars were more mesially inclined in the first group, particularly in the younger subjects (16～25 years).

用U检验对两组测量角度的平均值进行比较，Spearman 相关系数估计年龄因素的影响，用Logistic回归分析第三磨牙的萌出与第一磨牙、第二磨牙的轴倾度、性别和年龄之间的关系。

Three hypotheses is put forward, based on microexamination about sample evaporation during determaination of isotope abundance by thermal ionization:1. Only atoms uncovered by outer layer atoms can be vapoured; 2. Atoms covered by outer layer atoms can diffuse but cannot vapoure; 3. The probability of diffusion of isotope atoms is in direct proportion to its probability of evaporation.

根据对热表面电离源同位素丰度测量过程中样品蒸发的微观研究，提出如下三条假设：(1 )未被外层原子覆盖的原子才能蒸发；(2 )被外层原子覆盖的原子只能扩散不能蒸发；(3 )同位素原子的扩散几率与蒸发几率成正比。

The phenotypic mean values for the three populations and the midparental heterosis values for the two backcross populations were used for quantitative trait locus mapping and analysis, the genetic basis and correlations betweent the traits were analysed.

将三个群体的表型值和两个回交群体的中亲优势值进行了数量性状位点(quantitative trait locus，QTL)的检测及效应分析，初步分析了持绿性、充实度和产量等农艺性状的遗传基础和各性状间的相关关系。

The trifunctional polyhydric alcohol is more, the elasticity coefficient and surface hardness are higher. 2. Catalyst. The appropriate dosage of catalyst is determinated. To N-330, it is 0.15%; to N-220, it is 0.35%. 3. Filler. The more the solid filler is, the higher the properties of polyurethane elastomer are. The effect of liquid filler is more perplexing.

结果表明：三官能度聚醚含量增加，试样的弹性系数和表面硬度随之增大；固体填料含量增加，试样的弹性系数和表面硬度随之增大，液体填料的影响较为复杂；催化剂辛酸亚锡的合适用量为0.15%(N-330)或0.35%(N-220)。

Measure the width and length at three points on two ends and middle part of membrane by tapeline with an minimum scale of1mm, then calculate the area per roll membrane by multiplying mean length with mean width.

5.3 尺寸偏差Dimensional deviation 5.3.1 用最小分度值为1mm 的卷尺在卷材两端和中部三处测量宽度、长度，以长度的平均值乘以宽度的平均值得到每卷卷材的面积。

Concretely, there are 3 factors that directly influence the transformation by extent: teachers\' mathematics teaching experience, their mathematics view with which they tend to handle mathematical problems, and the transfixion degree of their understanding about mathematical knowledge.

具体来说，影响的直接因素有三个，按影响程度由大到小，它们依次是教师的数学教学经验、教师的问题解决取向的数学观、教师对数学知识理解的贯通度。

We are now two thirds around the building , a very strong point which culminates and completes

它是第三个循环的结束位置，这就好象我们已经完成建筑工程的2/3一样，这将是一个几乎无法超越的位置，足以结束20年的循环而形成顶点第5个60度

On the other hand, the more important thing is because the urban housing is a kind of heterogeneity products.

另一方面，更重要的是由于城市住房是一种异质性产品。

Climate histogram is the fall that collects place measure calm value, cent serves as cross axle for a few equal interval, the area that the frequency that the value appears according to place is accumulated and becomes will be determined inside each interval, discharge the graph that rise with post, also be called histogram.

气候直方图是将所收集的降水量测定值，分为几个相等的区间作为横轴，并将各区间内所测定值依所出现的次数累积而成的面积，用柱子排起来的图形，也叫做柱状图。
