First scanning the known handwriting materials then number them ,In pretreatment, we convert the valid part of the image into a standard size, as images carries out duotone and go throw off chirp handling in order to achieve better effect.draw features from the known handwriting materials with the Co-occurence,especially,we divided a copy of handwriting into 25 little pieces with the size of 128*128 ,drawing features from every little piecese with four directions(0 degree, 45 degrees, 90 degrees as well as 135 degrees) and calculate the four major feature values( veins and the statistical quantity of veins contrast and the statistical quantity of veins consistency Shang the statistical quantity of statistical quantity as well as the veins correlation of gray scale ), preservation all the feature value that drawn from all known ma terials to the handwriting characteristic database,then input the unknown handwriting materials, also using the method of the Co-occurence to draw those features, recycling the minimum European Distance law match the unknown writing material feature value with the handwriting characteristic feature database, export the label of the known hand writing materials which is most similar to the unknown material with minimum European Distance, and then we can confirm who is the author of the unknown material.
首先将笔迹材料作为图象扫描输入,并对其进行编号。预处理部分可将笔迹图象的有效部分规范化到一个统一尺寸,接着对其进行二值化和去除噪声的处理,以便于更好的提取图像的特征。在此我们采用了灰度共生矩阵法提取手写笔迹材料的纹理特征,与以往有所不同的是,我们将一份手写材料分割成64块大小为80*80象素的子图象,每个小块都从四个方向(0度、45度、90度以及135度)来更全面的提取特征,并计算出四个最主要的特征值(纹理一致性的统计量、纹理反差的统计量、纹理熵的统计量以及纹理灰度相关性的统计量),将从所有已知材料提取的特征值保存到纹理特征库中,对于待检手写材料,同样采用灰度共生矩阵的方法提取其纹理特征,再利用最小欧氏距离分类法将从待检手写材料中提取的特征值与纹理特征库中的特征值进行比对,与欧氏距离比对值最小的相匹配,输出匹配成功的原材料的标号,进而识别出待检材料书写者的身份。

Inflorescence a single, stiff, 2-sided raceme, spikelets arranged edgeways on, alternate in 2 opposite rows, their inner edges sunk in hollows of the tough rachis. Spikelets laterally compressed, florets several to many, uppermost florets reduced, disarticulating below each floret; glumes leathery; lower glume suppressed except in terminal spikelet and there similar to upper; upper glume abaxial, narrow, persistent, shorter than lemmas to as long as spikelet; lemmas membranous to leathery, rounded on back, 5–9-veined, with or without a subterminal awn; palea usually equal to lemma.
花序一单个,硬,2边的总状花序,小穗侧面压扁,小花数枚到多数,在每小花下面退化,脱节的最上部的小花;颖片革质;压抑的更低的颖片除了在顶生的小穗里和那里类似于上面;背面,狭窄,宿存的上面颖片,短于外稃在倍于小穗;外稃膜质到革质,在背面上圆形,5-9-脉,有或没有一芒;内稃通常等于外稃。

Liu Jin is one of the young and active artists now. His latest art experiments are all used his body as medium. His opuses aspire after feelings of releasing for using his body with pleasant sensation of being presence in the foreland of art experiments. Although his opuses contain some behavior art, I slide over to say that his art exploration is only the behavior art, it doesn't mean that behavior art is the wicked way for artists to get high reputation and flubdub, also it doesn't mean that the actual behavior art is target of public criticism in the government art criticism circles, we can say that because of many people just pay their attention to the Chinese meaning of "behavior". For this reason, it is similar to the performing art.
刘瑾是目前较活跃的年轻艺术家之一,他最近的艺术实验均以自己的身体为媒介,他的作品追求身体在执行作品的过程中的释放感和在场于艺术实验前沿的亢奋,尽管他的作品包含了许多的行为艺术因素,但我还是回避了以行为艺术来简单化的指称他的艺术探索,这既非是行为艺术在某些人眼里已成为哗众取宠,沽名钓誉的恶俗行径,也不是因为目前行为艺术在官方的艺术批评界已成为众矢之的,而是因为行为艺术这一名词本身在中文语境中过于看中行为本身,在这一点上,又同表演艺术相差不远。

The results show that the fluidization characteristics of scrap printed circuit board particles depend on the average size and type of particles. The scrap printed circuit boards particles, belonging to Geldart A group with strong viscous force, whose fluidization was similar to fluidization of Geldart C, was difficult to fluidize. Whereas, the scrap printed circuit board particles belonging to Geldart B can be fluidized smoothly.
实验结果表明,电路板塑料颗粒为Geldart A类颗粒时,粘性力大,塌落特性明显,流化性能较差,具有拟C类颗粒的流化特性;电路板塑料颗粒为B类颗粒时,塌落特征不明显,并且随着粒径的增大,最小流化速度也增大。

To evaluate the bioactivity of the glass-ceramics,the specimens were soaked in the simulated body fluid. The results indicate that fluorapatite shows needle-like microstructure, which is similar to that in human bone and teeth. The formation of needle-like fluorapatite is related to the heat treatment procedure, which results in needle-like fluorapatite crystals by accelerating one-dimension growth along the c-axis through the screw dislocation growth mechanism. The mechanical properties of the glass-ceramics are close to those of the human bone and teeth. The bioactivity test results show that apatite layer is precipitated on the materials surface after 3 d immersion in SBF, which indicates the glass-ceramics have a good bioactivity.
研究结果表明:氟磷灰石相呈针状,与人体骨和牙齿的磷灰石形貌相似,有利于提高材料的生物活性和生物相容性;氟磷灰石的形成是材料被迅速加热至高温进行热处理,使磷灰石以螺旋位错生长机制沿c轴晶化长大所致;经热处理获得的材料具有优良的力学性能,基本满足骨科和齿科用生物材料的性能要求;材料在体外模拟体液中浸泡3 d后,样品表面已有磷灰石层生成,表明该材料具有较高的生物活性。

In addition, can also be combined with the occasional inclusion of the tea flowers, fruits to determine if they fruitlet tea, it is estimated that fruit size similar to mung bean, it can be judged for the spring, because the tea is usually in the 9 November insemination is to spend the spring During the tea is a time when the young began to grow.
另外,还可以结合偶尔夹杂在茶叶中的花、果来判断,如果发现有茶树幼果,估计鲜果大小近似绿豆,那么可以判断为春茶,因为茶树通常在9~11月现花授精,春茶期间正是幼果开始成长之际。
