代码说明：

DFIELD6 is an interactive tool for studying single first order differential equations. When DFIELD6 is executed, a DFIELD6 Setup window is opened. The user may enter the differential equation and specify a display window using the interactive controls in the Setup window. When the Proceed button is pressed on the Setup window, the DF Display window is opened. At first this window displays a direction line field for the differential equation. When the mouse button is depressed in the DFIELD6 Display window, the solution to the differential equation with that initial condition is calculated and plotted. Oher options are available in the Options menu. These are fairly self explanatory. The Settings option allows the user to change several parameters. Included here are the possibilities of using a vector field instead of the default line field, and of changing the number of field points computed and displayed.

SRIMRangeDist
SRIM is a software that does Monte Carlo simulation of ion implantations. It can estimate the distribution of ions and target damages after an implantation. SRIMRangeDist helps SRIM users to plot the ion distribution data a SRIM output with relative ease. In some occassions, SRIM users need to calculate the distribution statistics of a series of several ion implantations and do a trial-and-error work to get the optimal implantation parameters. Performing this kind of task manually in a data processing software can be a bit mundane. SRIMRangeDist allows users to plot multiple implantation profiles on the same graph, and it computes the total distribution and the 95 confidence interval of the distribution for a quick reviewing of many implantation scenarios.

ChaosToolboxVer
小数据量法计算最大lyapunov指数工具箱，原来的那个工具箱中有点误差，现在改进了只对前一部分直线状数据进行计算，使结果更加准确(A small amount of data calculated index of the largest lyapunov toolbox, the original error that the toolbox a bit, and now has improved only in a straight line like the first part of the data is calculated so that the results more accurate)
