为了便于我们分析和识别电路，更好的理解555电路，这里我们这里按555电路的结构特点进行分类和归纳，把555电路分为3大类、8种、共18个单元电路。...

程序员对代码所做的为了满足短期利益代码改动，或再没有完全清楚增个架构下的改动，都很容易是代码失去它的清晰结构，偏离需求或设计。而这些改动的积累很容易使代码偏离它原先设计的初衷而变得不可立即和无法维护。 Refactoring则帮助重新组织代码，重新清晰的体现结构和进一步改进设计。 -programmers to code done in order to meet short-term interest code changes or not entirely clear by a framework of the changes, it is easy to lose its code is a clear structure, depart from the demand or design. And the accumulation of these changes are easier to make code from its original intention of the original design has become an immediate and unable to preserve. Refactoring is helping to reorganize code, re- clearly reflected structure and further improve the design.

１）按当前流行的以 IBM PC 为主机的开发系统对汇编语言的规定，读者不必再进行修改，便可直接使用。（２）对浮点运算子程序库进行了进一步的测试和优化，对十进制浮点数和二进制浮点数的相互转换子程序进行了彻底改写，提高了运算精度和可靠性。（３）新增添了若干个浮点子程序（传送、比较、清零、判零等），使编写数据处理程序的工作变得更简单直观。在使用说明中开列了最主要的几项：标号、入口条件、出口信息、影响资源、堆栈需求，各项目的意义请参阅《单片机应用程序设计技术》第六章 6.3.7 节的内容。程序清单中开列了四个栏目：标号、指令、操作数、注释。为方便读者理解，注释尽力详细。子程序库的使用方法如下：１．将子程序库全部内容链接在应用程序之后，统一编译即可。优点是简单方便，缺点是程序太长，大量无关子程序也包含在其中。２．仅将子程序库中的有关部分内容链接在应用程序之后，统一编译即可。有些子程序需要调用一些低级子程序，这些低级子程序也应该包含在内。优点是程序紧凑，缺点是需要对子程序库进行仔细删节。

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 .
