说明：  ABAQUS显式子程序用来计算材料是否破坏和对应刚度折减。(ABAQUE/Explicit subroutine vumat)

这个程序有Alpha的代码,不过太慢了,我一直无法使他支持MMX,唉!我的p54c(你不知道p54c p55c的区别?)...如果您改进了他或完善了,请给我一份好吗?让我们共同进步!-Alpha code, but too slowly, I have been unable to keep him support MMX, huh! I p54c (you do not know the difference between p54c p55c) ... If you improve his or refined, please give me a copy please let us make progress together!

说明：  用VB 6.0　＋　SQL Server200０ 编译写的图馆管理系统(Using VB 6.0 SQL Server2000 compiler written by library management system)

71篇关于超声波、心电等医疗电子相关资料(71 papers on ultrasound, ECG and other medical electronic information)

能量谱分析计算,有信道编码，调制，信道估计等，代码里有很完整的注释和解释。( Energy spectrum analysis and calculation, Channel coding, modulation, channel estimation, Code, there are very complete notes and explanation.)

PCI局部总线，对于做PCI卡的人来说，非常有帮助-PCI Local Bus, the PCI card to do people, very helpful

一个最优化方法的大作业 用了线性规划的最速下降法求解网络流问题(net problem fast descending)

说明：  将三相电流实施坐标变换后得到了M-T坐标系下的电流反馈值，再经过PID调节后，形成了电流闭环控制；且定子电流通过反变换后得到静止两相坐标系的定子电压给定值，再经过SVPWM控制逆变器，得以输出三相电压(The feedback value of the current in the M-T coordinate system is obtained after the coordinate transformation of the three-phase current. After PID adjustment, the current closed-loop control is formed.The stator current is inversely transformed to obtain the stator voltage value of the static two-phase coordinate system, and then the three-phase voltage can be output by the SVPWM controlled inverter)
