利用分形维数原理计算分段测井曲线的盒维数，从而定量化曲线分形特征。利用雷达图对分形数据进行分析。(The fractal dimension principle is used to calculate the box dimension of segmented logging curves, and the fractal characteristics of curves are quantified.)

本程序为扩展有限元程序，可以模拟裂纹扩展过程，如果内置裂纹开裂速率，可以进行试件疲劳寿命预测。(This program is an extended finite element program, which can simulate the crack propagation process and predict the fatigue life of specimens if the crack rate is in place.)

让距离进口10，长度为10的一段边界做振幅为10的正弦振动的程序(A program of sinusoidal oscillation with an amplitude of 10 at a distance of 10 and a length of 10.)

表示相空间相邻轨迹的平均指数发散率的数值特征。又称李雅普诺夫特征指数，是用于识别混沌运动若干数值的特征之一。(Denotes the numerical characteristics of the average exponential divergence of adjacent trajectories. Also known as the lyapunov characteristic index, is one of the characteristics used to identify some numerical values of chaotic motion.)

本程序基于蒙特卡洛思想生成电动汽车充电负荷曲线，利用第十一届电工杯所提供的数据（充电开始时间，充电电量，充电功率）得到一万台电动汽车充电负荷曲线。蒙特卡洛只是解决问题的一种思想，本程序可为其他利用蒙特卡洛的问题求解提供借鉴。(Based on the Monte Carlo idea, this program generates the electric vehicle charging load curve, and uses the data provided by the Eleventh Electrician Cup (charging start time, charging power, and charging power) to obtain the 10,000 electric vehicle charging load curves. Monte Carlo is just an idea to solve the problem. This program can provide reference for solving problems using Monte Carlo.)
