The extraction of these nutrient deficiency features was made and the extracted features were optimized and combined to pick the eigenvectors out for the design of a mode identifying assorter.

建立了二叉树分类法对番茄缺素进行模式识别的框架，在该框架下，基于模糊 K近邻法建立了缺素的模式识别系统，并进行了识别测试。

If the shaft seal bad back, there will be large number of resin powder leaked, each class should be pressed for several Pan-gen still leakage phenomenon not only affects the sanitation, and increase the volume of maintenance and therefore a need to use The system forms a seal 4 gear is reasonable Screw conveyor is the use of motor driven rotary screw, the passage of materials in order to achieve the purpose of transportation machinery, it can level, tilt or vertical transmission, a simple structure, small cross sectional area, sealing, and easy to operate, easy maintenance, facilitate closure transportation and other advantages.

如果轴后端密封不好，就会有大量树脂粉泄漏，每个班要压好几次盘根，仍有泄漏现象，既影响了环境卫生，又增加了维修量，因此急需选用一种适用于该系统的密封形式 4传动装置的合理性螺旋输送机是利用电机带动螺旋回转，推移物料以实现输送目的的机械，它能水平、倾斜或垂直输送，具有结构简单、横截面积小、密封性好、操作方便、维修容易、便于封闭运输等优点。

We propose a text vector space model base d on suffix tree and implement a text categorizing system on the model.

摘要］ 本文在面向网络内容分析的前提下，提出了一种基于后缀树的文本向量空间模型，并在此模型之上实现了文本分类系统。

What this tree style allows for, and one reason we're pretty keen on it, is that we aren't saying "You're a 'berserker' barbarian, you can't have whirlwind".

这个是技能树系统所提供的，同时我们喜欢看到的是：我们不会说"你是一个狂战士系野蛮人，所以你不能拥有旋风"。

In the present paper, recent advances in molecular phylogenetics and biogeography of Gaultheria are summarized and some problematical issues within the genus discussed.

Methods: We analyzed nucleic acid sequence of the SARS-CoV and SARS-like CoV which were obtained from the GeneBank. The evolutionary trees of SARS-CoV and SARS-like CoV were made up by using the Brede virus as outgroup, and analyzed variation in single nucleotide sequence.

对GenBank登录的SARS冠状病毒和SARS样冠状病毒(SARS-like CoV)核酸序列进行了分析，以Breda病毒为外组，构建了SARS冠状病毒和SARS样冠状病毒系统进化树，并进行单核苷酸变异分析。

PmMYB is a typical R2, R3-MYB transcription factor with its 2 typical DNA-binding domains (amino acid sites of 13-63 and 66-114).The multiple alignment of R2, R3 amino acid repeat regions of MYB genes among broomcorn millet, rice, corn, loblolly pine, Arabidopsis, capsicum, upland cotton, barley and aubergine indicates that R2, R3 repeat regions are very conserved. The phylogenetic analysis based on amino acid sequence shows that MYB genes are highly divergent with similarity ranging from 32% to 84%.

对其与水稻、玉米、火炬松、拟南芥、辣椒、陆地棉、大麦及茄子等9种植物的 MYB 基因的R2、R3重复区的氨基酸序列多重比较，表明R2R3重复序列在植物中具有较高的保守性；基于氨基酸序列的编码区系统进化树分析表明，不同植物的MYB基因遗传分化很大，序列相似性为32%~84%，其中糜子 MYB 基因与水稻的 MYB18相似程度最高(84%)，与大麦和玉米的相似性分别为46%和41%。
