Gompertz（龚伯次）曲线模型被广泛应用在预测中，该代码实现了G曲线的预测功能。(Gompertz curve is widely used in prediction, this code will help achieve the Gompertz curve prediction function.)

计算机辅助几何设计与非均匀有理b样条（修订版）施法中著；第6-7章附件(《CAGD & NURBS》)

for PSCAD softwear it can be very easy and coming soon challenger in this soft

图形学上机实验，用三种算法画线。包括Bresenham画线算法、中点画线和数值微分画线算法(Graphics on an experiment with three algorithms draw the line. Bresenham line algorithm, the dotted line and numerical differential line drawing algorithm)

实现本机流量监控绘图，测试可用，方便安全(Netflow monitoring)

等值线函数.// As this code is ported from FORTRAN-77, please be very careful of the // various indices like ilb,iub,jlb and jub, remeber that C/C++ indices // starts from zero (0)(contour function.// As this code is ported from FORTRAN-77, please be very careful of the// various indices like ilb, iub, and* address, remember that the C/C indices// starts from zero (0))

利用逐点法绘制出图形，图形的绘制其实都是由折线组成的，只是每条折线的误差太小了，肉眼根本分辨不出来(use of the point-by-point drawing graphics, the graphics are actually drawn from the composition of the dogleg, only broken each of error is too small, the human eye can not be seen)

画曲线图的c++例子，使用定时器去随机数的方式画图。(Draw the curve c example, use the timer to go the way of the random number drawing.)

AE实现加载CAD格式的数据，以及对其进行转换格式，转换为SHP等格式，还有对其进行编辑等操作(AE spatial data editing functions, including generating points, generating lines, as well as delete, move elements such as fried operation)

用C++模拟LBM的couette流源代码，使用周期边界和曲线边界条件。(LBM simulation using C++ source code of couette stream, using periodic boundary conditions and boundary curves.)
