说明：  这是一个以色列教授编写的计算转子动力学的程序(rotor dynamic This is a program written by an Israeli professor to calculate rotor dynamics)

说明：  利用对数极坐标到直角坐标系的变换实现不同拓扑荷数涡旋光束的并行检测，可用于光通信，以及对涡旋光性质的理解。整个仿真基于PRL文章“Efficient Sorting of Orbital Angular Momentum States of Light”(The parallel detection of vortex beams with different topological charges is realized by using the transformation from log polar coordinate to Cartesian coordinates, which can be used in optical communication and the understanding of vortex optical properties.The whole simulation is based on the article "efficient sorting of intrinsic angular momentum states of light" in PRL)

VB DataList用法-源码演示，这个数据库控件在VB编程中也是很常用的，这个例子是向新手介绍如何使用DataList控件的，挺简单，代码在VB6.0下可直接编译哦 。

采用ANSYS软件的APDL语言编写的两个命令流文件，用于计算含缺陷管道的失效概率，将参数稍作改动，可用于其它结构的可靠性分析(using ANSYS APDL preparation of the two documents order flow, used in the calculation of pipeline containing defects failure probability of parameters minor modifications, can be used for other structural reliability analysis)

说明：  ActiveMQ服务，简单直接启动即可，方便测试，第四部分(ActiveMQ service, simple and direct start, easy to test, Part IV)

能在MDT5/6环境下对已经存在地曲面进行全部和局部区域展开，同时能进行源曲面和展开平面上点和线地相互映射-in MDT5/6 right environment to surface already exists for all regional and local begin and can be the source for surface and start Plane dots and lines to the mutual mapping

矩阵求逆。输入任意的矩阵，能判断该矩阵是否可逆，如果可逆，能给出逆阵，否则，提示该矩阵不存在逆矩阵。-Matrix inversion. Arbitrary input matrix, the matrix can judge whether or not reversible, if reversible, can be given against the array, otherwise, suggesting that the matrix inverse matrix does not exist.

三相模块化多电平换流器，可以实现直流电压到三相电压的逆变，控制方式有两种(Three-phase modular multi-level converter can realize the inversion from DC voltage to three-phase voltage. There are two control modes.)

笔者首先提出了煤岩变形破裂过程电磁辐射与应力耦合的概念,然后在实验研究、理论分析和数值模拟的基础上从力电耦合的角度研究了煤岩冲击矿压预测的电磁辐射法(ＥＭＥ)。研究结果表明:ＦＬＡＣ3Ｄ方法能对矿山巷道掘进过程煤岩内部应力场进行有效的数值模拟 电磁辐射信号主要来源于应力集中区,在场点监测到的电磁辐射信号主要是应力集中区煤岩变形破裂过程产生的 ＥＭＥ信号呈现出与煤岩内部应力变化相同的规律 利用力电耦合方法研究煤岩冲击矿压电磁辐射预测法是可行的。笔者最后还对未来煤岩冲击矿压电磁辐射预测法的研究进行了展望。-first author of coal and rock deformation and fracture process of electromagnetic radiation coupled with the concept of stress, then the experimental research, theoretical analysis and numerical simulations on the basis of Congli coupling angle of coal and rock rockburst forecast of electromagnetic radiation (EME). The results showed : FLAC3D method to mine tunneling process of coal and rock internal stress effective numerical simulation of electromagnetic radiation signal comes mainly from the stress concentration areas, the monitoring point to the presence of electromagnetic radiation signal is mainly concentrated stress coal rock deformation and fracture process of EME signal showing the internal rock and coal Stress changes in the s
