有序无序转变的计算机模拟——MC算法 一个样品做实验，从低温有序相，逐渐升温，到高温无序相。 模型假设： 1 模拟三维简单斜方，AB型合金，共有M*N*L个原子； 2 最邻近假设，即只考虑最邻近原子之间的相互作用，次邻近和更远的原子之间的作用忽略（误差较大）， ，在简单斜方中，最邻近原子数z=6； 3 只考虑势能的作用，AA，BB，AB原子间的作用用Eaa,Ebb,Eab=Eba表示 且忽略振动能（原则上，温度很高时，不能忽略）等； 4 各原子之间的相互作用独立，即各化学键相互独立； 5 边界原子任然周期排列，只不过，邻近原子数减小，能量较高；边界面上的原子z=5；线 上的原子z=4，顶点上的原子z=3；由于顶点上只有四个原子，算法中不考虑这种情况； 6 其它假设。( Order-disorder transition of computer simulation- MC algorithm a sample experiment, from the low-temperature ordered phase, gradually warming up to a high temperature disordered phase. Model assumes that: 1 of three-dimensional rhombic, AB-type alloy, a total of M* N* L atoms 2 nearest the assumption that only consider the interaction between the neighboring atoms, and further sub-adjacent atoms ignore the interaction between the (larger error), , in the simple oblique Fang, nearest neighbor atoms, z = 6 3 only consider the potential role, AA, BB, AB interatomic with Eaa, Ebb, Eab = Eba representation and ignore the vibration energy (principle, the temperature is high, it can not be ignored), etc. 4 each atom interactions between independent, which means that each bond independently 5 boundary periodic arrangement of atoms in any course, but , adjacent atoms decreases, the higher energy boundary atomic plane z = 5 atoms on line z = 4, the vertex atoms z = 3 only four)

图像对齐（inage registration）工具箱，非常完整，包括帮助文件等。非常难得的，强烈推荐！(Image Alignment (Inage registration) Toolbox, a very complete, including help files. Very rare, strongly recommended!)

时隙ALOHA协议是对ALOHA协议的简单修改，把传输时间分为一个个时隙，数据包只能在时隙的开始进行并行传输。在当前的时隙中产生的数据包只能在下一个时隙的开始进行并行传输。(Time slot ALOHA protocol is simple modification of ALOHA protocol, the transmission time is divided into a time slot, packets can only be the beginning of time slot for parallel transmission. In the current time slot of packets can only be the beginning of the next time slot for parallel transmission. )

说明：  研究能量受限的SWIPT无线通信网络中，基站采用MIMO多天线发送信号给用户节点，在有窃听节点的情况下，通过联合优化发射波束形成矢量、人工噪声协方差和接收PS比来最小化总发射功率，同时保证每个接收机的个体保密率和能量收集约束。(In the energy limited swipt wireless communication network, the base station uses MIMO multi antenna to send signals to user nodes. In the case of eavesdropping nodes, the total transmit power is minimized by jointly optimizing transmit beamforming vector, artificial noise covariance and receive PS ratio, while ensuring the individual confidentiality rate and energy collection constraint of each receiver.)
