中国科学院研究生院老师的PPT，对于初学mathematica的人来说，可以借鉴下，了解mathematica的主要功能(Chinese Academy of Sciences, Graduate School of the teacher s PPT, beginner mathematica for people who can draw on, the understanding of the main functions of mathematica)

说明：  智能小车循迹，超声波避障，红外遥控功能。基于89c51单片机平台。(Intelligent car tracking, ultrasonic obstacle avoidance, infrared remote control function. Based on 89C51 single chip computer platform.)

experiment equipment: stm32F103 C8T6 Purpose: ADC real-time sampling shows waveforms through an anonymous host computer (virtual oscilloscope) ADC1 and serial 1 dual DMA use to speed up the transfer rate Hardware resources: 1, ADC1 channel 1 (peripheral A1) 2, serial port 1 (baud rate: 500000) Experimental phenomena: The anonymous host computer displays the waveform in real time. The sampling frequency of the ADC is about 1Mhz (the highest value of the single ADC mode has been reached, but the maximum transmission rate of the host computer is about 500000 baud. And only one byte per transfer of 14 bytes is valid (caused by the anonymous transfer protocol). It takes about 2.8ms to transfer once.

说明：  shapefile数据，全国范围四级河流数据(river data shapefile)

（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.)
