he power method will be applied to the jacobian matrix of the 2-D henon map to approximate the first Lyapunov exponent by creating a graph of ln|yn| vs. n, where n is the number of iterations of the power method and yn = 1/n*ln|DG^n(xo)*yo|. The slope will be an approximation to the largest Lyapunov exponent.(he power method will be applied to the jacob ian matrix of the 2-D map to approximate henon th e first Lyapunov exponent by creating a graph of ln | yn | vs. n, where n is the number of iterations of the power m ethod and yn = a/n* ln | DG ^ n (xo)* yo |. The slope w ill be an approximation to the largest Lyapunov exponent.)

Koch曲线是通过图形迭代的方式产生的，其迭代规则是：对一条线段，首先将它分成三等份，然后将中间的一份替换成以此为底边的等边三角形的另外两条边。无限次迭代下去，最终形成的曲线就是Koch曲线。(Koch curve is generated by way of graphical iteration, and its iteration rule is: for a segment, it is divided into three equal parts first, and then replace the middle of a bottom side of this equilateral triangle to the other two edges. Infinite iterations continue, the final form of the curve is the Koch curve.)
