高斯投影坐标正反算
正反算的实质
正算公式是将大地坐标(B,L)求解高斯平面坐标(X,Y)，反算公式是将高斯平面坐标(X,Y)求解大地坐标(B,L)
高斯投影的特点
（1）投影后中央子午线为直线，长度不变形，其余经线投影对称并且凹向于中央子午线，离中央子午线越远，变形越大。
（2）赤道的投影也为一直线，并与中央子午线正交，其余的经纬投影为凸向赤道的对称曲线。
（3）经纬投影后仍然保持相互垂直的关系，投影后有角度无变形。

EvaluateReversePolishNotation
Evaluate the value of an arithmetic expression in Reverse Polish Notation.
Valid operators are +, -, *, /. Each operand may be an integer or another expression.
Some examples:
[ 2 , 1 , + , 3 , * ] -> ((2 + 1) * 3) -> 9
[ 4 , 13 , 5 , / , + ] -> (4 + (13 / 5)) -> 6
分析：这一题就是写程序计算逆波兰式的结果，遍历表达式，碰到操作数入栈，碰到操作符就从栈顶取出两个操作数，再将计算后的结果入栈，最后栈中剩余的唯一操作数就是计算结果。(.

[" 2" , " 1" , " +" , " 3 " ," * " ]-> ((2+ 1)* 3)-> 9 [" 4 " ," 13 " ," 5 " ," /" ," + " ]-> (4+ (13/After this problem is to write a program to calculate the inverse Polish results, iterate expression operand stack encounter, encounter operator to fetch two operands the stack, and then calculated as follows:> 6 Analysis- 5)) The results of the stack, the only remaining operand stack is the final calculations.)

RFID读卡模块电路图、PCB源文件
125K RFID读卡模块，包含UART输出，韦根输出，程序中，根据曼彻斯特原理，找到长电平和短电平，根据跳变沿分析出0数据还是1数据。然后寻找消息头，后面的数据进行 行 列奇偶校验，从而分析出卡号。(125K RFID card reader module, including UART output, Wei root output, in the program, according to the principle of Manchester, to find a long level and a short level, according to jump along the analysis of 0 data or 1 data. Then look for the message header, and then the data for row and row parity check, so as to analyze the card number.)

lθn =每一类中允许的最少模式数目(若少于此数不能单独成为一类)，
lθs =类内各分量分布的距离标准差上界(大于此数就分裂)，
lθD=两类中心间的最小距离下界(若小于此数，这两
