课程设计中首先采用Ising model的思想建立一个二维的模型,然后利用重要性抽样和Monte Carlo方法及其思想模拟铁磁-顺磁相变过程。计算了顺磁物质的能量平均值Ev、热容Cv、磁化强度M及磁化率X的值,进而研究Ev、Cv、M、X与温度T的变化关系并绘制成Ev-T图、Cv-T图、M-T图、X-T图,得出顺磁物质的内能随着温度的升高先增大而后趋于稳定值;热容Cv、磁化率X随着温度的升高先增大后减小;磁化强度M在转变温度Tc处迅速减小为零,找出铁磁相变的转变温度Tc大约为2.35(First of all, curriculum design idea of the Ising model used to establish a two-dimensional model, the importance of sampling and then use Monte Carlo simulation methods and their idea of ferromagnetic- paramagnetic phase transition process. Paramagnetic material calculated average energy Ev, heat capacity Cv, magnetization M and susceptibility X value, and then study Ev, Cv, M, X and temperature changes in the relationship between T and plotted into Ev-T map, Cv- T diagram, MT map, XT maps drawn paramagnetic material can be increased as the temperature increased and then stabilized value heat capacity Cv, magnetic susceptibility X as the temperature increases after the first minus small magnetization M in the transition temperature Tc decreases rapidly to zero Department to identify ferromagnetic phase transition around the transition temperature Tc for 2.35)

lms
最小均方算法lms在波束形成中的应用 LMS算法步骤: 1,、设置变量和参量: X(n)为输入向量,或称为训练样本 W(n)为权值向量 b(n)为偏差 d(n)为期望输出 y(n)为实际输出 η为学习速率 n为迭代次数 2、初始化,赋给w(0)各一个较小的随机非零值,令n=0 3、对于一组输入样本x(n)和对应的期望输出d,计算 e(n)=d(n)-X^T(n)W(n) W(n+1)=W(n)+ηX(n)e(n) 4、判断是否满足条件,若满足算法结束,若否n增加1,转入第3步继续执行。(Lms least mean square algorithm applied in Beamforming
