树是由n(n≥0)个结点组成的有限集合T。n=0的树称为空树；对n>0的树，有:(1)仅有一个特殊的结点称为根结点，根结点没有前驱结点；(2)当n>1时，除根结点外其余的结点分为m(m>0)个互不相交的有限集合T1,T2，…，Tm，其中每个集合Ti本身又是一棵结构和树类似的子树。 -Tree is n (n ≥ 0) consisting of nodes finite set T. n = 0 of the tree known as the empty tree for n> 0 of the tree, there is: (1) has only one special node called the root node, root node there is no precursor node (2) when n> 1 when, with the exception of root node except the node is divided into m (m> 0) a finite set of mutually exclusive cross-T1, T2, ..., Tm, one of each set Ti is itself a structure and are similar subtree tree .

这是我从网看到的，不用电平的转换IC就可以把串口TTL输入、输出的电平转换成计算机能识别的电平，原图经测试不能用，经我改进后效果很好，大家不妨一试-This is what I see from the network, not power conversion IC level can be the serial TTL input and output level into the computer to identify the level, the maximum should not have been tested, and improved by my very good , we may as well try
