LS-DYNA材料的二次开发-1

计算三相四线制电压负序不平衡度，零序不平衡度，(three-phase voltage unbalance factor)

关于某大型斜拉桥建模命令流，可以作为铁路斜拉桥ansys建模参考(As for the modeling command flow of a large cable-stayed bridge, it can be used as a reference for ANSYS modeling of railway cable-stayed bridges)

本程序为扩展有限元程序，可以模拟裂纹扩展过程，如果内置裂纹开裂速率，可以进行试件疲劳寿命预测。(This program is an extended finite element program, which can simulate the crack propagation process and predict the fatigue life of specimens if the crack rate is in place.)

说明：  基于自适应滤波算法的通信系统中微弱信号检测程序(Weak Signal Detection Program in Communication System Based on Adaptive Filtering Algorithms)

以江苏丰县为例，展示了城区基准地价更新监测系统。 需要自行添加使用区域地价数据库（ArcGIS制作）。(Taking Jiangsu Fengxian County as an example, shows the monitoring system of the urban standard land price update. Need to add the use of regional land database (ArcGIS).)

高级SQL Server监控,性能图,分析与优化,版本控制源码(Advanced SQL Server monitoring, performance diagram, analysis and optimization of version control of source code)

说明：  sar adc ic5141 可以安装在csmc0.5um工艺库下面(sar adc ic5141 csmc0.5um)

说明：  海水温盐深剖面测量设备的串口实时数据采集实现Deep-sea water temperature and salinity profiling serial devices to achieve real-time data acquisition(Deep-sea water temperature and salinity profiling serial devices to achieve real-time data acquisition)

用红外控制步进电机转动角度，并且用LCD显示，采用51单片机控制，转速误差在1%之内(With infrared control stepper motor rotation angle, and with LCD display, using 51 single-chip microcomputer control, speed error is within 1%)

说明：  用弹簧单元模拟钢筋和混凝土的滑移，模拟非线性接触问题。(De veereenheid wordt gebruikt om de slip van staal en beton te simuleren om niet-lineaire contactproblemen te simuleren.)
