遍历堆，可以对一个堆编立，复制，采用函数的递归调用来实现的(Traverse the heap, the recursive call to compile a heap legislation, copy, use the function)

说明：  1. 定义了刀具和工件结点的接触，并定义为默认“硬接触” 2. 工件上表面定义了自接触，防止切屑穿透工件上表面 3. 有些情况下可能产生工件右边界的部分结点卷曲后进入上表面，可以额外定义工件上表面与右边界部分结点（在右边界上，但是被切下来的部分结点）的接触算法这样就不会穿透了。(1. Defined the contact between tool and workpiece node, and defined as the default "hard contact". 2. Self-contact is defined on the upper surface of the workpiece to prevent the chip from penetrating the upper surface of the workpiece 3. In some cases, part nodes of the right boundary of the workpiece may curl into the upper surface, and the contact algorithm between the upper surface of the workpiece and the right boundary part node (the part node on the right boundary, but the part node cut off) can be defined in addition, so as not to penetrate.)

java实现正则表达式的代码，加上我自己写的测试的例子，是用jbuilder实现的-achieve expression of code, coupled with my own writing test example is the use of JBuilder realized

用RBF神经网络算法对非线性干扰进行估计，提高控制精度，并将其与普通滑模控制进行比较。(The RBF neural network algorithm is used to estimate the nonlinear disturbance, and the control accuracy is improved.)

类似音量控制的VB滑块应用实例源码，很多个排列整齐的滑块，可在鼠标的操作下拖动位置，实现某种功能，可用于程序参数面板中，用于设置某项参数和数值，具体效果请参见截图。
