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

该程序实现的是种子生命的模拟,生存:有两个或三个邻居的种子将存活到下一代,即仍然占据该格子;
死亡:如果有四个或更多的邻居,种子将因为过度拥挤而死亡;如果种子只有一个或零个邻居,将因为孤独而死亡;
繁殖:如果一个空格子有三个邻居,那么将会长出一粒新种子。一种模式在经过若干代之后有以下四种可能的结局之一:
消亡;
不变――静态;
振荡――在一组模式间循环多次后在相同的位置出现相同的模式;
滑动――在一组模式间循环多次后在不同的位置出现相同的模式。该程序允许用户指定初始的模式或计算机自动创建初始的模式;
显示进化的过程,即历代模式;
当模式消亡就停止进化,或者提示用户是否继续显示下一代,或开始新的案例,抑或退出。
-The program implementation is the seed of life simulation, survival: There are two or three neighbors of the seed will survive to the next generation, that is still occupying the lattice
Death: If there are four or more neighbors, the seeds will die because of overcrowding if seed is only one or zero neighbors, will die because of loneliness
Breeding: If a sub-space has three neighbors, then it will grow a new seed. After a pattern after several generations have the following one of four possible outcomes:
Die
Constant- static
Oscillation- a group of modes in the loop on many occasions in the same location after the same pattern emerged

Visual C# 隐藏、显示开始按钮
C# 隐藏、显示开始按钮,把Windows的开始菜单隐藏起来,看不到“开始”菜单了,Windows7则隐藏了窗口图标,不过这样会很不方便哦,本源码只是学习C#与Windows之间的相关编程技巧,下面的代码实现了隐藏显示开始菜单的功能:
[DllImport("user32.dll")]//寻找窗口列表中第一个符合指定条件的顶级窗口
public static extern int FindWindow(string lpClassName, string lpWindowName);
[DllImport("user32.dll")]//在窗口列表中寻找与指定条件相符的第一个子窗口
public static extern int FindWindowEx(int hWnd1, int hWnd2, string lpsz1, string lpsz2);
[DllImport("user32.dll")]//控制窗口的可见性
public static extern int ShowWindow(int hwnd, int nCmdShow);
private void button1_Click(object sender, EventArgs e)
{
if (radioButton1.Checked)
ShowWindow(FindWindowEx(FindWindow("Shell_TrayWnd", null), 0, "Button", null), SW_HIDE);//隐藏开始按钮
else if (radioButton2.Checked)
ShowWindow(FindWindowEx(FindWindow("Shell_TrayWnd", null), 0, "Button", null), SW_SHOW);//显示开始按钮
}
