键盘输入有抖动，本程序利用计数器法来消除键盘输入信号的抖动 还有一篇关于键盘防抖研究的论文...

本计算器实现了计算器的基本的运算功能，以及使用比较广泛的函数功能，可作为函数功能型计算器使用，同时为了方便实用，本人进行了统计功能的编程，使本计算器可以用于简单的统计。在编程时只使用了最基本的方法，未用到特别的技术。本程序的执行文件过大是一个较大的问题，在今后的学习中会逐渐改进，将程序进行分块儿，以提高执行效率。-the calculator calculator achieved the basic computing functions, and the use of more extensive Function can be used as a functional calculator use, in order to facilitate the practical, I conducted a statistical functional programming, so that the calculator can be used in simple statistics. When the program to use only the most basic of ways, not the particular technology used. The procedures are too big and is a major problem in the next study will gradually improve, procedures pm deadline, in order to enhance the efficiency of enforcement.

用来计算电偶极子的电场和电势分布，当然也可以根据需要计算更高阶的电场，只要保留到相应的阶次就OK了。-This program computes the electric field and potential distributions of a dipole. You can also compute higher order electric field with it by preserving the series to corresponding order.

利用编译原理的思想实现的科学计算器，功能比较齐全-The idea of using the compiler to achieve the principle of the scientific calculator, function relatively complete
