查询词典 pruning

Dead branches or knots in different sizes of tree was studied and different branch development phases of growth,suppression,death and self-pruning was analyzed to evaluate the effect that knot size and distribution impact on timber quality.Branch and knot dynamic models were developed using stand and tree variables.Based on multipleunit stepwise regression method, the individual tree growth model was established using forest and crown factors as the variable. The best taper equation model of Larix olgensis was bucking data of 130 sample trees selected in the studied area.

本研究以不同年龄、不同密度及不同立地条件的落叶松人工林作为研究对象，基于19块标准地中95株标准木的树干解析、枝解析及节子剖析数据，揭示了不同林分条件下林木的枝条数量及在树冠内的空间分布格局、生长发育规律；研究了不同大小树木的死枝和节子大小及其变化规律，分析了枝条的生长、被压、寿命和自然整枝过程，评价了节子大小和分布对木材质量的影响；以林分变量、林木变量和着枝深度等为自变量建立枝条生长和节子大小的动态预测模型；选择林分因子和林木的树冠因子作为竞争因子，用多元逐步回归的方法建立落叶松人工林与距离无关的单木生长模型，并根据研究地区选取的130株造材样木数据，建立了落叶松人工林最佳削度方程。

Now, scientific farming has been applied in all aspects of farming, the old methods have been eliminated, orchard pruning of young people, most of the village hired agronomists, spring improvements, may be next year after a high yield.

现在，科学种田已经适用在耕作的方方面面，老的方法已经被淘汰，果园里修剪的年轻人，大多是村里请来的农艺师，今春的改良，可能就是明后年的丰产。

Based on the Least Squares Support Vector Machines method, Incremental LS-SVM and Online LS-SVM method is proposed for identification of structural systems in this paper. It efficiently updates a trained LS-SVM by means of incremental and decremental pruning algorithms whenever a sample is added to, or removed from, the training set. The method overcomes the drawback of sparsenesslost within the standard LS-SVM and makes online training for the LS-SVM possible.

本文在最小二乘支持向量机方法的基础上提出了用于识别结构系统的增量最小二乘支持向量机和序贯最小二乘支持向量机方法，当新样本加入进来或老的样本被修剪下去的时候可以有效地更新，这种方法克服了标准最小二乘支持向量机方法的稀疏性缺失，使得结构参数的在线识别成为可能。

This thesis discusses firstly the IGMP, describes the specification of the protocol and explains the differences between the three different versions of protocol. Then the RPF rule used by the router to forward multicast packets and the multicast forwarding tree are discussed. The process of building SPT and RPT is also illustrated. In this thesis, we also discuss the mechanism of Flooding and Pruning in Dense-Mode multicast routing protocol and the process of switch from RPT to SPT in Sparse-Mode routing protocol.

本论文讨论了实现IP组播的IGMP协议，对IGMP协议的协议规范进行了描述，并对IGMP三个版本的不同点作了详细说明；讨论了进行组播数据包进行转发的RPF基本原理、组播转发树的类型，并对SPT树和RPT树的建立过程进行了探讨；并分别对密集模式组播路由协议的扩散和剪枝机制、稀疏模式组播路由协议中的RPT树到SPT树的切换过程进行了详细的探讨。
