说明：  　本文对变步长自适应滤波算法进行了讨论,建立了步长因子μ与误差信号e(n) 之间另一种新的非线性函数关系. 该函数比已有的sigmoid 函数简单,且在误差e(n)接近零处具有缓慢变化的特性,克服了Sigmoid 函数在 自适应稳态阶段步长调整过程中的不足. 由此函数本文得出了另一种新的变步长自适应滤波算法,并且分析了参数α,β的取值原则及对算法收敛性能的影响. 该算法有较好的收敛性能且计算量少. 计算机仿真结果与理论分析相一致,证实了该算法的收敛性能优于已有的算法.(In this paper, variable step adaptive filter algorithm to discuss the establishment of a step factor μ and the error signal e (n) between another new nonlinear function. The function has a sigmoid function than the simple and the error e (n) close to zero Department has a slow change in the characteristics of a Sigmoid function to overcome the steady-state phase in the adaptive step length adjustment during the process. this function, this paper gives another new variable step size adaptive filtering algorithms, and analysis of the parameters α, β the value principles and the convergence performance. The algorithm has better convergence performance easy to calculate. Simulation results and theoretical analysis, confirmed the convergence of the algorithm better performance than existing algorithms.)

此程序以美国黄石国家公园为例，构造尽可能贴近实际的仿真环境，从而通过仿真得到野火发生频率与野火规模之间的数学模型。这是一个经典的幂率模型，稍作改造好即可模拟“28原则”、“网站点击率”等幂率相关问题。(This procedure to Yellowstone National Park as an example, the actual construction simulation environment as close as possible to the simulated wildfire through the frequency and size of wildfires between the mathematical model. This is a classic power law model, slightly modified to better simulate " 28 principles" , " web site click-through rate" and other power-law related issues.)
