广东 林木种苗工程项目资金 使用管理的问题与对策

The utility model relates to a bag for preserving water content for tree roots .

本 实用 新型涉及一种 树木用保墒袋。

We made use of the C4.5 decision tree algorithm as well as the WEKA utility for data mining and decision tree modeling . Rules in the model are described in sequence to establish a reliable monitoring and diagnosis mechanism .

利用C4.5决策树分类方法，使用WEKA 工具对数据进行数据挖掘并得到决策 树模型，对模型中的规则进行业务分析并逐条描述，建立一个较为可信且具有长期有效的监控、诊断机制。

One utility I occasionally use is a program that calls other programs iteratively over a tree of files .

我偶尔使用这样一个 实用 程序， 它针对一个文件 树反复调用其他程序。

After a while the marginal utility is negative : the tree becomes an irritation offering neither use nor ornament .

过了一段时间后，边际 效用就为负了：这 棵 树变成了令人恼火的东西，既没有使用 价值，又不能做装饰。

The build utility removes the build tree after the packages are made ( & clean ) .

构建 实用 程序在生成包之后删除构建 树（&clean）。

Generate Quality Attribute Utility Tree .

生成质量属性 效用 树。

This paper summarized and analyzed the present situation and existing problems of financial utility and management of engineering project of tree seeds and seedlings in Guangdong Province . The proposals and countermeasures were raised for the future utility and management work of funds .

概述了广东省 林木种苗工程项目资金 使用与管理现状，分析了其存在的主要问题，并提出解决问题的相关建议。

The utility model is not only suitable for tree planting but also suitable for the other planting field like flowers and vegetables .

不仅 适用于 植树，还可适用于花卉蔬菜等其它种植领域。

The utility model provides an integral petroleum production tree which is characterized in that a pipe cross and mutually connected main bars are a hollow and cuboid integral forging piece ;

本 实用 新型提供一种整体式采油气 树，其特征是四通和相互连接的主杆为一个空心长方体的整体锻压件；

Identify prioritize and refine the most important quality attribute goals by building a utility tree .

通过建立一个 有效 树，来明确、排序和精炼大部分的质量目标。

I think we can postulate a utility function along the following lines : having a Christmas tree up during the Christmas season brings positive utility but diminishing marginal utility over time .

我觉得我们可以按照以下思路来假定一个 效用函数：在圣诞节期间有一棵圣诞 树可以带来正的效用，但随着时间流逝，边际效用就会递减。

Finally based on the Utility theory and with the help of the Decision Tree solve the dispatching decision of later stage .

前期研究应急物资调运模型；后期以 期望 值理论为基础借助决策 树进行调运方案的决策分析。
