Glabripennis. The research of ability of arresting of host trees and moulds to A. glabripennis showed that there was a recognition process involving feeling, gustation and olfaction after the beetle landed on host trees or models, then the beetle made its choice to accept or reject host trees after comprehensive recognition.

This reporter immediately rushed to the scene, dozens of workers are still busy scene shipment off of trees, These trees higgledy-piggledy heap to a dozen dumplings, a big tree diameter of about 30 cm above were split into about a meter long wooden, Small trees more than 10 cm in diameter was also split into three meters in length.

记者立即赶往现场，十几名工人还在现场忙着装运砍下的树木，这些树木横七竖八地堆了十几堆，大的树直径约30厘米以上的都被截成约1米长的木段，小的树木直径约十几厘米的也被截成3米左右的长度。

Because the various countries' national condition and the geographical position are different, Arbor Day is not same in the various countries' name and the time, like Japan is called "the tree knag" and "the afforested week"; Israel calls "trees' new year date"; Burma is called "the tree-planting month"; Yugoslavia is called "the tree-planting week"; Iceland is called "the student to plant trees Japan"; India is called "the national Arbor Day"; France is called the national trees date "; Canada is called "the forest week.

由于各国国情和地理位置不同，植树节在各国的称呼和时间也不相同，如日本称为"树木节"和"绿化周"；以色列称"树木的新年日"；缅甸称为"植树月"；南斯拉夫称为"植树周"；冰岛称为"学生植树日"；印度称为"全国植树节"；法国称为全国树木日"；加拿大称为"森林周。附件：你需要登录或注册后才能查看。

The traditional query tree optimization methods,parallel database optimization methods based on left linear trees and right linear trees,bushy trees,and operation of the forest,have their own pros and cons,they have been more in-depth and maturity of the study.The query optimization method based on multiple weighted tree has studied its model of parallel query plan,its complexity model of parallel query plan and query optimization algorithms.The semantic query method transforms an inquiry into one or several semantic equivalence inquiries then has to find and implement a strategy to achieve a better query.Agent-based parallel database query optimization using Multi-Agent technology to automatically search the integrity constraint conditions which are related to the determined query,there for,the efficiency between several relations' joins has been greatly improved.The parallel optimization algorithm,based on genetic algorithm which is suitable for multi-joins of cluster environment,has deeply studied the relations storage options,multi-joins query optimization and query processing and other key technologies based on cluster parallel database.

传统的查询树优化方法，即基于左线性树、右线性树、浓密树、操作森林的并行数据库查询优化方法，各有优劣，对其的研究比较深入、成熟；基于多重加权树的查询优化方法，研究了其并行查询计划模型、并行查询计划的复杂性模型和查询优化算法；语义查询优化方法将一个查询变换成一个或数个语义等价的查询，进而寻找并执行这些等价查询中具有较好实现策略的一个；基于Agent的并行数据库查询优化采用Multi-Agent技术自动查找与给定查询有关的完整性约束条件，使得多个关系间连接操作的效率得到很大的提高；基于遗传算法的并行优化算法，深入研究了基于机群并行数据库中关系存储的选择、多连接查询优化和查询处理等关键技术。

In this paper,lower bounds on the spectral radius of adjacency matrices of trees and perfect trees are discussed by algebraic method and edge switching of graph,and all trees which reach lower bounds on the spectral radius are obtained.

利用代数方法、图的边变换，以及树的邻接矩阵谱与L ap lacian谱的关系，研究树和完美树的邻接矩阵谱半径和L ap lacian谱半径的下界，给出达到下界的所有极树，得到的新结果改进了文献[2]的结论。

Three, Column telome garden applications for more telome, trees or old trees, if trees are tilting instability, the need to set up Oeda sag support pillars, and pillars to a solid (usually made of metal, wood piles, reinforced Coagulation column, etc.) to connect the top and the trunk should be entrusted to set up the appropriate rods and occasional bowl, add a pad to avoid damaging the bark.

三、立柱顶枝园林应用较多的为顶枝，大树或古老树，如有树身倾斜不稳时，大枝下垂需设支柱撑好，支柱要坚固（一般用金属、木桩、钢筋混凝柱等）上端与树干连接处应设适当的托杆和托碗，加软垫，以免损害树皮。

This paper presents a maximum criterion-based phylogeny analysis method for unrooted trees. To increase the confidence level of the derived evolutionary trees, we use bootstrapping and consensus analysis in conjunction with a genetic algorithm for crossover and mutation between evolutionary trees.

本论文采用最大概率字元特徵式的评分方式，以及无根的建构方法，利用基因演算法对所有可能的树的子树做交配与突变，再使用统计自序法与一致演化树法来增加树的可信度。

Scholaris and Coffea arabica (2.500 kg). Nine to eleven months after planting, A. scholaris trees grow very fast. Total biomass per plant of seed-propagated trees is 28.41kg, 3.21 times that of vegetatively propagated trees. Therefore, it is recommended that seed-propagated seedlings be used in A. scholaris production.

移栽定植后9~11个月是糖胶树生长的最快阶段；用种子进行苗木繁殖的糖胶树，其单株总生物量为28.41 kg，是营养繁殖的3.21倍，在生产上大面积推广时宜采用糖胶树种子进行幼苗繁殖。
