使用源代码实现链

用于加入分布式电源的电力系统选址定容，方便实用。(It is convenient and practical for locating and sizing power system with distributed generation.)

this document is about fluidization.

说明：  （1）设计一个“简易计算器”，主要实现判断输入的表达式是否合法将中缀表达式转换成二叉表达式树。后序遍历求出表达式的值。能判断输入的表达式是否合法。 （2）用链式存储存储信息，求值时可以采用递归的思想，对表达式进行后序遍历。 （3）将操作结果保存到外部文件。((1) Design a "simple calculator" to judge whether the input expression is legitimate or not and convert infix expression into binary expression tree. The value of the expression is obtained by post-order traversal. Can judge whether the input expression is legitimate. (2) Store information in chain mode. When evaluating the value, we can use the idea of recursion to carry out post-order traversal of the expression. (3) To save the operation results to external files.)

一个学校用的教务管理系统和成绩查询系统-微信小程序源码，里面包括了一个成绩查询系统，可以使用学号登录，然后查询某个课程的成绩，并对课程计划进行安排，程序功能暂时没有那么多，有些模块还没有写，目录结构挺完整，可作为一个学习微信小程序开发的初级例子吧，运行的界面效果如截图所示。
