种差异

The result shows that in total 75.6% species are under the "10 × rule", 80.5% species possess unique DNA barcode sequences by which they could be identified. On the other hand, 19.5% species (including 8 species of Buteo) are difficult to be distinguished by DNA barcoding.

结果显示，75.6%的猛禽符合10×规则，且80.5%的猛禽均具有独特的DNA条形码可作为物种鉴定的依据，另有19.5%的猛禽（鵟属8种猛禽）由于种间差异太小，DNA条形码对它们的识别鉴定存在一定局限。

In the first approach the metadata extraction is viewed as a classification problem. Three statistic classification models, including Support Vector Machines, Perceptron with Uneven Margins, and Maximum Entropy are studied. The approach suffers from the problems of ignoring the variance in lengths of documents and ignoring the dependency of text units within documents. To solve the problems, our second approach takes the metadata extraction as a sequence data labeling problem and makes full use of the sequential information.

论文首先研究了基于分类的元数据抽取方法，考察了支持向量机、非对称间隔感知机和最大熵模型在ADME中的应用；然后针对分类方法中存在的忽略文档之间的差异、不考虑文档上下文等问题，提出了基于序列数据标注模型的抽取方法，并结合最大熵马尔可夫模型、投票感知机模型和条件随机场模型进行了研究；最后本文根据前两种方法的设计思想和优缺点，研究提出一种新的结构预测模型—— CDASP（Coordinate Descent Algorithm for Structure Prediction），并将其应用于元数据的自动抽取中。

RELATIONSHIPS AMONG BODY SIZE ,CLUTCH SIZE , AND EGG SIZE IN FIVE SPECIES OF OVIPAROUS COLUBRID SNAKES FROM ZHOUSHAN ISLANDS ,ZHEJIANG ,CHINA

阐明五种游蛇科动物雌体大小，窝卵数和卵大小之间的关系和雌性繁殖特征的种间差异。

PAL activity, chitinase activity, total Polyphenol content and total Flavonoids content in soybean leaves induced by the same crude toxin and race were similar, it stated that the crude toxin is an important factor which can induce resistant substances, but the induced speed and the induced intensity by the crude toxin and conidium were different. Firstly, the induced speed of crude toxin which induced PAL activity and total Flavonoids content of resistant soybean varieties was faster than speed of C.

同一生理小种的粗毒素与灰斑病菌对大豆叶片内PAL活性、总多酚类含量、总黄酮含量以及几丁质酶活性等几种生化指标均表现出相似的诱导作用，由此可推断粗毒素是诱导大豆叶片内的PAL活性、总多酚含量、总黄酮含量以及几丁质酶活性产生变化的主要生物因子，只是二者在对抗性不同的大豆品种的诱导速度及强度上存在一定的差异。

Test results show that there are evident differences among creepage distance utilization coefficients of different types of insulators.

对华东电网常用的几种绝缘子的积污特性、爬电距离有效利用系数进行了分析和计算，同时，在污秽试验的基础上，对几种常见的绝缘子试品进行了长串耐压试验，试验结果表明，不同类型绝缘子的爬电距离有效利用系数存在较大差异。

Three of the five types of small mammal in the more fragmented habitats (namely, the north-western deer mouse, the montane shrew and Trowbridge's shrew) were smaller. The difference in size was between 5% and 15%—small but significant.

栖息在较分散区域中的5种小型哺乳动物中，有3种（即西北鹿鼠、山地食虫鼠和特洛布里奇食虫鼠）体型越来越小，大小变化在5%至15%之间，虽然差异不大，但意义非同寻常。

Methods The cDNA retro-transcribed from equal quantity total RNA derived from rectal carcinoma or normal rectal mucosa were labeled with Cy5 or Cy3 fluorescence as probes respectively. The mixed probes were hybridized with the BioStar 4096 cDNA microarray.

分别抽提直肠腺癌和正常直肠粘膜的总RNA；通过逆转录方法将Cy3和Cy5两种荧光分别标记到两组cDNA上，制成探针；利用这种cDNA探针与含有4096条人类基因PCR产物的表达谱芯片进行杂交，扫描芯片荧光信号图像，计算机分析后比较两种组织中差异表达的基因。

Methods Analyzed the survival rate,the level of sensory recovery,the length of operative incision and the surgical time of two different methods for the treatment of the fingers tip defect and bones of fingers niditas,one method is fascial flap shift and planting back in natural position or dermatoplasty,the other method is regional flap shift.

运用筋膜瓣转移+原位回植术及局部皮瓣转移修复术治疗指端软组织缺损，对两种手术方法的手术时间、手术切口长度及指端成活率、感觉恢复程度的对比分析，了解两种手术方式的差异。

The decomposition of chromosome was a main problem in construction of BAC library. DNA discompose would be avoided or decreased by adjustments of component and pH of chromosome extraction buffer or pre-electrophoresis for 6-8h before digestion. Identification of inter-species hybrids was a necessary step for creating a new germplasm. Two samples were selected from offspring of hybridization and backcross of a cross between cabbage and Chinese cabbage.

鉴定种间杂种是利用远缘杂交创造新种质时的一项重要工作，本研究运用细胞核DNA含量流式测定技术，对甘蓝和白菜杂交及回交各世代的DNA含量进行检测，以监控遗传物质在不同材料间的流向，并从回交二代植株群体中筛选了两个材料，具有和白菜差异不显著的DNA含量，可推断其为核质杂种。

DNP and NaN〓 could inhibit the rHV2 transport and implied that the rHV2 absorption is concerned with energy.

经大鼠口服三种微球制剂的药效学实验表明微球制剂与原料药没有差异，即三种制剂对rHV2的口服吸收均没有改善作用。

She gently rebuff ed him, but agreed that they could be friends

她婉言拒绝了，但同意作为朋友相处。

If in the penal farm, you were sure to be criticized.

要是在劳改农场，你等着挨绳子吧！
