说明：  超声波探头聚焦声场仿真和水浸探头以及相控阵探头，可以通过设置探头频率和探头直径，模拟超声发射声场，实用性强。(The simulation of focused acoustic field of ultrasonic probe can simulate the acoustic field of ultrasonic emission by setting probe frequency and probe diameter, which is practical.)

进行matlab倍频程声压级处理的程序。由于是一个项目的一部分，有一些属于项目的函数没上传，未找到的函数删除后即可使用。(Program for octave sound pressure level processing)

说明：  通过把分散在时间轴上的离散数据看成一组连续变化的序列，采用累加和累减的方式，将灰色系统中的未知因素弱化，强化已知因素的影响程度，最后构建一个以时间为变量的连续微分方程，通过数学方法确定方程中的参数，从而实现预测目的。(By regarding the discrete data scattered on the time axis as a series of continuous changes, and adopting the way of accumulation and subtraction, the unknown factors in the grey system are weakened, and the influence degree of the known factors is strengthened. Finally, a continuous differential equation with time as variable is constructed, and the parameters in the equation are determined by mathematical method, so as to achieve the prediction purpose.)

说明：  构建晶体塑性模型，晶粒之间的动力学关系，可以预测晶体取向、晶粒形态、织构等(The crystal orientation, grain morphology and texture can be predicted by constructing the crystal plasticity model and the dynamic relationship between grains)

一个不错的数控源码是vb的，很不错的写的，大家可以-NC a good source is vb, and the writing is pretty good, we will look at

又一个GDI+图形绘制及颜色填充实例，以前发过一些GDI绘图的例子，不过只是绘制图形，没有填充功能，这个实例可以填充所画出来的几何图形，多了一些功能，不过同样挺简单，测试运行效果如截图所示。
