由于该公式是一超越方程式，无法直接求解，为此，作者又从数学上作了适当的函数变换，通过变换，最后建立了两端球铰的伸缩油缸临界力的计算公式。

The characteristic parameters of tree belt, such as tree belt width, density, average canopy density, height, and distance from the source to the tree belts were included in the formula.

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。

Satisfiability is the problem of determining if the variables of a given Boolean formula can be assigned in such a way as to make the formula evaluate to TRUE.

满足的问题是确定的变量，如果某一布尔公式可分配的方式，使公式评价为

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。
