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。

And at the same time, through discussing the mechanism of earth wave absorbing tomography, it is known the CT of seismic absorption imaging method is better than the wave velocity imaging method in the identify ability of faultage crushed zone whose body structural plane is flabbiness and the dimensions is small.

阐述了地震波在粘弹性介质传播过程中具有的衰减特性，探讨了地震波吸收层析成像的机理，得知地震吸收CT成像方法，对岩体软弱结构面、裂隙和规模较小的断层破碎带的识别能力，要强于波速成像方法。

The 2-D transfer function of the bistatic SAR is obtained. Azimuth position distortion along range existing in the original alogrithm is corrected by mapping from scene coordinate to azimuth-slant distance coordinate. Bistatic SAR date can still be processed by a mono-static SAR processor. The efficaciousness of the proposed algorithm is verified through point target simulations.

算法通过数值计算得到双基地二维传递函数，通过场景坐标系向方位－斜距平面的映射校正了原算法中存在的沿距离变化的方位位置畸变，进而来用常规单基地SAR成像处理流程实现对双基地SAR回波数据的成像处理，最后通过点目标仿真验证了算法的有效性。

OBJECTIVE: To study the regulation of bFGF on the blast-colony-forming cell by adding bFGF in the medium of embryoid body generation.

目的：在拟胚体培养阶段施加碱性成纤维细胞生长因子，验证碱性成纤维细胞生长因子对集落形成细胞产生的调控作用。

Sp. tritici of the F1 plants were tested at the seedling and adult stages. The results indicated that dominant and semi-dominant genes were responsible for powdery mildew resistance at the seedling stage, while dominant, semi-dominant and recessive genes were found controlling the powdery mildew resistance at the adult plants. After testing the Pm30 linked SSR marker Xgwml59 on the 40 F1 hybrids between wild emmer and common wheat, it was found that the Pm30 linked Xgwm159 loci could be detected at 8 F1 hybrids, indicating the 8 wild emmers might also carry the Pm30 gene.

对F_1植株的苗期和成株期抗性鉴定结果表明，在这些野生二粒小麦材料中，苗期抗性由显性和部分显性基因控制，而成株期抗性则由显性、部分显性和隐性基因控制。40份F_1代材料经Pm30基因连锁的SSR标记Xgwm159的测定，有8份材料可能含有Pm30基因。

It is said that when Wang Zhou, one day he and his brother playing tert-Yu, to cut a piece of Indus leaves the shape of Yu-kyu, p-tert-Yu said:"I use this to enfeoffment on you."

相传周成王小时候，有一天他和弟弟叔虞玩耍时，把一片梧桐叶剪成玉圭的形状，对叔虞说："我就用这个来分封你吧。"

But in SD rats, cardiac muscle fibers were fractured seriouly , contracted to wavilness obviously, then muscle fibers fracture were contracted like entasia by the hypoxia time increased , injury intensify , all the changes refered SD rats compensatory mechanism can not be transferred in this hypoxia degree. 3. Exposed to 4% oxygen concentration, the cardiac muscle ultrastructure of Gansu zokors had serious injury after hypoxia 2h.

在4%氧浓度的低氧耐受实验中，甘肃鼢鼠在低氧2，4h后，心肌纤维收缩明显呈波浪状，低氧时间延长至6，8和10h后，心肌显微波浪状收缩由强逐渐变弱，并逐渐恢复至正常状态，说明鼢鼠心肌在6h以后对严重缺氧环境开始代偿性适应；SD大鼠2h组心肌纤维断裂严重，收缩加强成明显的波浪状，随着低氧时间得增加，4h组呈严重成挛状收缩，损伤加剧，提示SD大鼠在这一氧浓度下已经无法正常调动其代偿机制。3。

Objective To assess the diagnostic value of CT enterography in patients with Crohn's disease. Methods Multi-detector CT enterography and small bowel follow-through were performed in 30 patients with Crohn's disease.

目的 将多层螺旋CT小肠成像与传统的小肠造影进行对比，了解CT小肠成像对克罗恩病的诊断价值。

CT enterography and small bowel follow-through consistently depicted fistula in 3 patients and had no significant difference in diagnosing intestinal stenosis. CT enterography also exclusively detected abdominal abscess in one patient.

"Evolution" was first used in Preformationism and then in Epigenesis, respectively, to describe the unfolding of preexisted organic structure and the recapitulation of the forms of lower animals by the embryo of higher animals. Then the meaning of species change was added to it in the beginning of the nineteenth century.

"Evolution"一词先后被用在胚胎学的预成论和后成论中，分别用来描述预先存在的有机体结构的展开以及高等动物胚胎对低等动物形式的重演。19世纪初它又被添加上了物种改变的含义。
