二叉

This is to use C language implementation of the binary tree traversal algorithms, including recursive and non-recursive algorithm implementation.

详细说明：这是用C语言实现的二叉树的遍历算法，包括递归和非递归算法的实现。

Decision tree is a tree-shaped diagram used to indicate the processing logic as a tool .

详细说明：决策树是用二叉树形图来表示处理逻辑的一种工具。

The use of binary tree to calculate the formula for the true value.

详细说明：（1）利用二叉树来计算公式的真值。

Stack will be the first to use infix form of the formula into the form of the suffix and then form the basis of the suffix from the beginning of leaf nodes corresponding binary tree structure Finally after by traversal of the tree, and the value of the subtree, that is, for every arrival a node, the value of its sub-tree has been calculated, when the reach the root node, the obtained value is the formula of true value.

首先利用堆栈将中缀形式的公式变为后缀形式；然后根据后缀形式，从叶结点开始构造相应的二叉树；最后按后序遍历该树，求各子树之值，即每到达一个结点，其子树之值已经计算出来，当到达根结点时，求得的值就是公式之真值。

In this thesis, our research work mainly focuses on the following aspects: 1, To the question of the large depth of the tree structure of scene database in building environment, and need take much time on search node, to table a proposal of regularization restrictions on the BSP tree construction, for the sake of obtaining balanceable BSP tree, to improve the system efficiency.

本文的主要研究工作如下：(1)针对室内环境场景数据库的树型层次结构深度比较大，进行节点搜索时花费的时间比较大的特点，提出对BSP树的构造进行规则化限制，得到较为平衡的二叉树结构，来提高系统运行过程中对BSP树进行遍历的效率。

However, few studies have investigated the consequences of induced plant response due to previous insect attack on phloem-feeding insects. Herein we address whether the feeding behaviour and growth of a phloem-feeding insect are affected by host plant changes with scientific research methods using three varieties resistant wheat 98-10-30, Amigo and Batis, which are from three different countries.

本研究通过严谨的实验方法，即选定3个不同国家的小麦抗性品种98-10-30、Amigo和Batis，在所有条件严格统一的人工智能控制温室内，通过各处理在同一植株上先后不同的接蚜方式，分别测定了麦二叉蚜Schizaphis graminum和麦长管蚜Sitobion avenae Fab。

The split between the two groups can hardly be papered over.

这两个团体间的分歧难以掩饰。

This approach not only encourages a greater number of responses, but minimizes the likelihood of stale groupthink.

这种做法不仅鼓励了更多的反应，而且减少跟风的可能性。
