说明：  载波侦听多路访问。采用分布式控制方法，附接总线的各个结点通过竞争的方式，获得总线的使用权。只有获得使用权的结点才可以向总线发送信息帧，该信息帧将被附接总线的所有结点感知(Carrier Sense Multiple Access. A distributed control method, each attached to the bus node on a competitive basis, to obtain the right to use the bus. Only with the right to use the node can send messages to the bus frame, the message frame will be attached to all nodes sense the bus)

L utilisation d intégrateurs limités permet de "clamper" à 0 la valeur basse de Ired et de Vs. Simulink simule des équations mathématiques dans lesquelles le comportement unidirectionnel des semi conducteurs n est pas exprimé. Sans cette précaution, un courant Ired<0 pourrait apparaî tre en régime transitoire.

sumt法，具有二次收敛性，若目标函数为二次正定函数，经有限步可达到极小点(sumt method, with quadratic convergence, if the objective function is quadratic positive definite function can be achieved by the finite step minima)

PageRank模型在中文情感词极性判别中的应用(PageRank model in the Chinese emotional polarity discrimination in the application of the word)

Particle swarm optimization has been used to solve many optimization problems since it was proposed by Kennedy and Eberhart in 1995 [4]. After that, they published one book [9] and several papers on this topic [5][7][13][15], one of which did a study on its performance using four nonlinear functions adopted as a benchmark by many researchers in this area [14]. In PSO, each particle moves in the search space with a velocity according to its own previous best solution and its group’s previous best solution. The dimension of the search space can be any positive integer.

通过matlab软件计算图像的峰值信噪比的大小。程序通过验证可以使用的。(Calculate the size of the peak signal to noise ratio of the image by matlab software. Program can be used by validation.)

The number π is a mathematical constant that is the ratio of a circle s circumference to its diameter and is approximately equal to 3.14159. It has been represented by the Greek letter "π" since the mid-18th century, though it is also sometimes romanized as "pi
