This paper makes complete and embedded research on methods of flow pattern identification , and brings forward neural network with feature extracted to distinguish flow pattern , at the same time validates and estimates this method with experimented data from experimentation 本文针对现有的基于ect的流型辨识方法进行了较为全面深入的研究，在大量的仿真分析基础上，提出了一种基于特征提取的神经网络流型辨识法，并在现有的实验装置中用实测数据进行验证和评估。
According to the statistic features , false objects are cleared and the true objects of the heads are extracted to choose the invariable features of the objects . finally , on the base of the normal algorithms about multi - object tracking , the feature - based tracking approach is adopted to track and count the kind of multi - object in the algorithm , in which the tracking and counting is one of the difficulties 并根据统计特征清除了伪目标，提取出人头部真正目标，选择了能反映目标不变特征；最后，在比较几种常用多目标跟踪算法的基础上，本算法采用特征跟踪方法对该类多目标进行跟踪计数。
12 . 26 % ) . further smoking quality test indicated that after the addition of condensate of oriental tobacco extract to flue - cured tobacco leaves , quality of aroma increased , while offensive odor and irritant decreased . furthermore , with the increasing condensate of quality score in tobacco leaves , richness and sweetness of smoke improved in a way , and the flavor quality was the best when quality score ( concentration ) of oriental tobacco extract was 70 % 12 . 26 % .进一步的评吸结果表明，在烤烟烟叶中加入香料烟浸膏后，可使香气质改善，香气量增加，杂气，刺激性减轻，而且当加入浸膏的质量分数增大时，烟气浓度和甜度有所增高，不同处理相比较，浸膏质量分数为70 %时，烟气的香吃味质量最好
Then , the minimum circumscribed circle and shape principal orientation of the object region are calculated ; and the object region is divided into some blocks in the polar coordinate , which uses the center of the minimum circumscribed circle as the origin and the direction of the shape principal orientation as the direction of the polar axis , and the features of all subblocks are extracted to compose shape histograms and then smoothed ; then , combined with global features to synthetically represent the content of the image ; finally , a new image similarity is used to compute the distance between images 首先对商标图像进行预处理,得到规则二值图像;计算目标像素的最小外接圆和图像的形状主方向;在以最小外接圆圆心为原点、形状主方向为极轴方向的极坐标中将图像分块,提取各子块特征,构成形状直方图并平滑处理;再结合全局形状特征来综合表示图像内容;最后采用新的相似性度量方法计算图像间距离,实现商标图像的准确检索。
To be successful , the watermark must be unperceivably and permanently embedded into the data : that is , after any distortion process , it can also be extracted to prove ownership , to recognize the identity of a misappropriate ^ to trace the dissemination of the data through the network , or to authenticate the integrity of the data 成功的水印必须是不可察觉地，永久地嵌入在数据中。即使数据发生失真，也能够从中提取出水印，来证明所有权，识别非法使用者的身份，跟踪数据在网上的分布，或鉴定数据的真实可靠性。
Recently , human elongator complexes have been isolated . the human complex is a fragile six - subunit complex that interacts with rnap ii and has hat activity directed against histone h3 and h4 . depletion of elongator from hela nuclear extracts reduces the ability of these extracts to transcribe chromatin templates , providing biochemical support for the proposed role of elongator during transcript elongation in chromatin 近来人elongator也被分离，它也是个不稳定的六亚基复合物，可与rnap相互作用，具有hat活性，能乙酰化h3和h4 ，在hela细胞核抽提物中去除elongator可降低抽提物对染色质模板的转录延伸速率，提供了该复合物在染色质为模板的转录延伸中有功能的生化证据，但是上面的信息都来自体外研究。
Is specially formulated with the combination of cracked spores powder , ginseng and grape seed extract to further enhance the body s well being . it also combine vitamin c , b1 , b2 and b6 to aid better absorption in gastrointestinal tract thus strengthen the efficacy of the ling zhi spores 独特配方的红日牌灵芝三合一孢子粉，采用破壁灵芝粉，配合人参和葡萄籽的精华制成，充分发挥保健功能，同时附加维他命c b1 b2和b6 ,能加强肠胃的吸收能力，更全面及快速提升孢子粉的超强疗效。
The method of calculating the equivalent temperature using double ir band radiant intensities is also studied . from the rv and decoy ’ s equivalent temperature data sequences , the temperature feature is extracted to discriminate the rv and decoy , and the decision rule is designed 论文还研究了使用双波段红外辐射强度数据测量弹道目标等效温度的方法,根据弹头与诱饵对应点目标的等效温度的变化规律,提取出三个温度特征参数,并设计了对应的判决准则用于区分弹头与诱饵。
The neutron flux extracted to different angles has been calculated . finally , the heat depositions in the target , the reflector and the moderator have been calculated . based on these results , the temperature and stress distribution hi tungsten target under different cooling condition have been calculated too 最后计算了靶、反射体以及不同慢化器(水、液态氢、液态甲烷)中的热量沉积，并以此为依据，利用工程软件ideas进一步计算了各种冷却条件下，靶中温度场与应力场分布。
