查询词典 nodes

Firstly the properties of L-MAX frequent itemsets is analysed.Then by extending FP-tree structure an ExFP-tree data structure is presented and the algorithm of ExFP-tree generated is given.According to the character of prefixing paths shared in FP-tree,ExFP-tree implements compressingly storage of transaction information with sharing the transaction information of descendant nodes.

ExFP-tree利用FP-tree共享前缀路径的性质通过共享子孙节点事务信息策略实现大量事务信息的压缩存储；最后基于FP-MAX算法，提出基于ExFP-tree的L-MAX频繁项集挖掘算法，核心思想是先根据L-MAX频繁项集长度约束性质进行前瞻剪枝再进行最大频繁项集挖掘，并通过回溯策略直接定位生成对应事务集。

Two-dimensional electrophoresis (2-DE) was used to study the variation expression of proteins of cucumber cotyledonary nodes induced with PP333. The characteristics and functions of differentially expressed proteins were analyzed with MALDI-TOF-TOF/MS and Protein Data Bank.

According to our result, the regeneration rate of embryonic tips explants was obviously higher than that of cotyledonary nodes when the concentration of 6-BA was from 0.5mg/L to 1.0mg/L, and the optimal inducing time was 5d.

理想的遗传转化受体系统不仅要有较高的植株再生率，而且要有一定的丛生芽数目。利用0.5～1.0 mg/L的6-BA诱导培养5d，大豆胚尖的出芽率、植株再生率及胚尖丛生芽数等综合指标较好。

On the basis of regeneration system of cotyledonary nodes, using Agrobacterium tumefaciens, the Mn-SOD gene was introduced into cucumber plants to express excessively, to improve ability of cleaning ROS and stress tolerance on environmental stress. The new Mn-SOD transgenic materials could be used for study of resistance physiology.

本研究在优化黄瓜再生体系的基础上，通过根癌农杆菌介导法，将Mn-SOD基因转入黄瓜植株，使SOD在植株体内过量表达，提高其在环境胁迫下清除活性氧的能力，从而提高黄瓜植株的抗逆性，并为抗性生理的研究提供有价值的材料。

Soybean cotyledonary nodes were transformed with S gene of IBV via A..tumefaciens-med\ated transformation.

通过根癌农杆菌介导对传染性支气管炎病毒纤突蛋白S基因在大豆中的遗传转化进行了研究。

从动态的观点出发，以发展的思维研究了基于城市空间形态的道路交通与广场的互动关系。

Research results indicate that continuous Regional Identification Function is used in nodal virtual flux method, volumn integral and surface integral enhances the convergence and stabilization;using 'put a big number' to deal with the first boundary is faster than 'Remove row and column', the more the first boundary nodes are the more obvious advantage will display;PCG method is quite faster than Crout method to solve equations;it is reliable to use three-dimensional finite element simulation theories to simulate and predict deep foundation pit dewatering in such areas.

研究结果表明，在结点虚流量法及计算体积分和面积分时引入连续的区域识别函数增强了解的收敛性和稳定性；处理已知水头边界的&置大数&法在时间上要比&去行去列&法短一些，定水头边界节点越多，其优越性表现越明显；PCG法比直接解法快很多；三维有限元数值模拟理论用于模拟预测此类地区的深基坑降水具有较高的可信度。

At last, the subgroup and structural position were analyzed based on the UCINET software, which shows 298 nodes, namely 22 kinds cruciferae plant, were divided into two subgroups and five structural positions, and Brassica napus played a key role in subgroups and structural position.

基于软件UCINET对网络进行了小团体和结构同型性分析，可将网络中298个节点22类十字花科植物划分为2个小团体和5类结构角色，其中甘蓝型油菜在转基因油菜基因流网络小团体中具有关键性作用。

Longest spines of lower glume equaling or longer than glume width, 1.5–2.5 mm; nodes of rachis minutely hairy; leaf blades glabrous, apex cuspidate.

更低的颖片等长或更长于颖片宽度，1.5-2.5毫米的长刺；轴微小的的节有毛；无毛的叶片，先端骤尖。 5 E。 zeylanica 马陆草

The major factors for callus induction, differentiation, and Agrobacterum-mediated transformation were investigated in the current paper, using the creeping stem nodes of Cynodon dactylon as the original materials.

以主要暖季型草坪草狗牙根的匍匐茎节为试验材料，对其愈伤组织的诱导、分化以及农杆菌介导转化的关键因子进行优化，以此为基础将除草剂抗性基因bar导入狗牙根中，并对抗除草剂狗牙根的推广应用作了探讨。

We have no common name for a mime of Sophron or Xenarchus and a Socratic Conversation; and we should still be without one even if the imitation in the two instances were in trimeters or elegiacs or some other kind of verse--though it is the way with people to tack on 'poet' to the name of a metre, and talk of elegiac-poets and epic-poets, thinking that they call them poets not by reason of the imitative nature of their work, but indiscriminately by reason of the metre they write in.

索夫农 、森那库斯和苏格拉底式的对话采用的模仿没有一个公共的名称；三音步诗、挽歌体或其他类型的诗的模仿也没有——人们把&诗人&这一名词和格律名称结合到一起，称之为挽歌体诗人或者史诗诗人，他们被称为诗人，似乎只是因为遵守格律写作，而非他们作品的模仿本质。

The relationship between communicative competence and grammar teaching should be that of the ends and the means.

交际能力和语法的关系应该是目标与途径的关系。
