说明：  实现画一个六边形，再均匀撒一些点，在六边形内部的点为红色，在外部的点为蓝色(six point point)

peec电路电感和互感计算的解析公式，精确解，适用于peec等效电路，分布式电网络(Peec circuit inductance and mutual inductance calculation of analytical formulas, the exact solution, apply to the peec equivalent circuit, a distributed electric network )

常规PID控制器主要采用模拟PID控制器。这种控制器的控制规律是：根据给定值和输出值构成的偏差按比例、积分和微分通过线性组合构成控制量，对被控对象进行控制。(Conventional PID controller is used mainly analog PID controller. This controller is the control law: according to the given value and output value constitutes a deviation by proportional, integral and differential form by a linear combination of the amount of control, control of the controlled object.)

说明：  复杂网络中社区划分算法中利用边介数的经典GN算法(Complex network community partitioning algorithm using edge betweenness classic GN algorithm)

encoding and decoding based on arithmatic operators may be used for compression

example qpsk modulation
