为了克服林带声衰减量计算过于简化而引起的公路交通噪声预测精度降低的不足，基于植物内部结构及吸声、散射机理的分析，建立了高速公路林带声衰减量计算公式，公式中包含了林带宽度、密度、平均灌幅、高度和林带近路侧距公路中心线距离等特征参数。

The results show that not only the porosity does greatly affect the windbreak, but also the tree distance does. The distance is not beyond 1.3 to avoid air leak. The tree belt with porosity 31% has bigger windbreak range and better characteristics for abating wind erosion. The tight nubby tree belt is advised to restrain the particles adhering on the leaves refloating for large velocity deficit in trees.

结果表明：不仅林冠疏透度对防护林带的遮蔽防风有明显影响，而且树木间的株距对林带整体的遮蔽效果也有比较显著的影响，为避免穿流风对遮蔽效应的影响，林带宽距比不宜超过1.3；疏透度为31%的网状林带的有效防护范围大，防风效果好而且水土保持性强；紧密型块状林带，林后速度衰减幅度大，可抑制附着在叶片上粉尘的再次扬尘。

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。
