实现客户端和服务器端的通信，但是功能很有限，只是单向的通信。(To achieve client and server-side communication, but function is very limited, only one-way communication.)

NVP6134B AHD RX 芯片支持300MP摄像机(The NVP6134B AHD RX chip supports 300MP cameras)

简易TCP通讯服务器端，QosClt为客户端。多个客户端间的通讯需要基于服务器，即通过服务器转发。(Simple TCP communication server, QosClt for the client. Communication between multiple clients need a server-based, that is transmitted through the server.)

GPS跟踪器原理图，源码程序，app程序V2.03版本，需要做定位跟踪的是个非常好的源码程序哦。(GPS tracker schematics, source program, app version V2.03 program, we need to make locating and tracking program is a very good source Oh.)

zoj094 Matrix multiplication problem is a typical example of dynamical programming. Suppose you have to evaluate an expression like A*B*C*D*E where A,B,C,D and E are matrices. Since matrix multiplication is associative, the order in which multiplications are performed is arbitrary. However, the number of elementary multiplications needed strongly depends on the evaluation order you choose. For example, let A be a 50*10 matrix, B a 10*20 matrix and C a 20*5 matrix. There are two different strategies to compute A*B*C, namely (A*B)*C and A*(B*C). The first one takes 15000 elementary multiplications, but the second one only 3500. Your job is to write a program that determines the number of elementary multiplications needed for a given evaluation strategy.

电话本系统是实现的功能是对通讯录的增删改查，是基于C/S三层架构的，用C#实现(Phone function of the system is to achieve is to address book additions and deletions to the investigation, is based on the C/S three-tier structure, with the C# implementation)
