高压直流输电仿真模型，基于晶闸管控制的12脉波MATLAB/SIMULINK仿真(The example in this section illustrates modeling of a high-voltage direct current (HVDC) transmission link using 12-pulse thyristor converters [1]. Perturbations are applied to examine the system performance. The objectives of this example are to demonstrate the use of SimPowerSystems blocks in combination with Simulink blocks in the simulation of a complete pole of a 12-pulse HVDC transmission system. The Discrete HVDC Controller block is a generic control available in the Discrete Control Blocks library of the SimPowerSystems Extras library. In the same library you can find the Discrete Gamma Measurement block used in the inverter control subsystem.)

朱邦芬只保留电子-声子互作用算符 对角项，把非对角项作为微扰处理； 原则上，不同的电子态对应于不同的晶格平衡位置；通常计算固体的振动性质时，假定电子处于基态。 (Zhu bonfim retain only electronic- phonon interaction diagonal operator, the diagonal of the non-perturbative as processing in principle, different electronic states corresponding to different lattice equilibrium position usually calculate the vibration of the solid nature, it is assumed that e in the ground state.)

主成分分析方法在各个变量之间相关关系研究的基础上，用较少的新变量代替原来较多的变量，而且使这些较少的新变量尽可能多地保留原来较多的变量所反映的信息一种方法。(Principal Component Analysis in the relationship between the various variables on the basis of the study, with fewer new variables replace the original more variable, but made them less a new variable as much as possible to retain the original variables that reflect more information methods)
