说明：  udp客户端以及服务器实现udp协议，用简单的程序实现其最基本的功能(UDP protocol implementation)

获取计算机硬件信息的动态链接库，CPU序列号，硬盘序列号，MAC地址等信息 例程： void gethardinfo() { QString str1=""; char buff[1024]; char buff2[1024]; char temp; typedef int (WINAPI ICEPUB_MACHINEGETINFO)(int typeFlag,char *strInfo); ICEPUB_MACHINEGETINFO *icePub_machineGetInfo = 0; HINSTANCE hDLLDrv = LoadLibrary("icePubDll.dll"); if(hDLLDrv) { icePub_machineGetInfo = (ICEPUB_MACHINEGETINFO *)GetProcAddress(hDLLDrv, "icePub_machineGetInfo"); } icePub_machineGetInfo(3,buff); str1=buff; int i=0; int n=0; n=str1.length(); qDebug()<<n; for(i=0;i<n;i+=2) { temp=buff[i]; buff2[i+1]=temp; buff2[i]=buff[i+1]; } QString str2=buff2; qDebug()<<buff2; qDebug()<<str2; }(Access to the computer hardware information dynamic link library, CPU serial number, hard disk serial number, MAC address and other information)

This is the design of a application which drive an AVR mcu to record and broadcast WAV voice stored in an Memory card.

sqlite-3_3_7 源代码，最稳定的sqlite源码，可以编译成linux、windows、mac等版本(sqlite-3_3_7 源码)

Distributed Index for Matching Multimedia Objects using MapReduce

航迹生成的算法，用于在线规划任务航线的资料。(The algorithm of track generation is used to plan the data of mission route online.)

使用编写服务器与客户端界面并用Socket实现通信。(The interface between server and client is written and the communication is realized with Socket.)

STM32的时钟显示模块，注意没有自动生成hex文件(clock module in STM32)

PIC PROGRAMS FOR MICROCONTROLLER

牛顿－拉夫逊法潮流计算 基本步骤： 　　（1）形成节点导纳矩阵 　　（2）将各节点电压设初值U， 　　（3）将节点初值代入相关求式，求出修正方程式的常数项向量 　　（4）将节点电压初值代入求式，求出雅可比矩阵元素 　　（5）求解修正方程，求修正向量 　　（6）求取节点电压的新值 　　（7）检查是否收敛，如不收敛，则以各节点电压的新值作为初值自第3步重新开始进行狭义次迭代，否则转入下一步 　　（8）计算支路功率分布，PV节点无功功率和平衡节点柱入功率。(Newton-Raphson method flow calculation basic steps : (1) formation of nodal admittance matrix (2) to set up the initial node voltage U, (3) the initial node-generation-related demand. calculated that the constant term formula Vector (4) nodes will be incorporated into the initial voltage-seeking, calculated Jacobian matrix elements (5) solving that equation, seek to amend the vector (6) to strike a new node voltage value (7) to check whether convergence, if not restrained. concentrated in the nodes of the new voltage as the initial value since the first three steps to re-start the narrow iterations. Otherwise, turn into the next (8) Calculation branch power distribution, PV nodes reactive power and balance-node into power.)
