In this paper , we combine both Efficient Market Hypothesis and Fractal Market Hypothesis to test our bond markets return distribution , the main results are that the index of Chinese bond market process by fractional Brownian Motion, the orbit is stable Pareto Distribution with α character So, the fractal market hypothesis is more suitable than the efficient market hypothesise

本文结合有效市场假说与分形市场假说理论，通过对我国证券市场中收益率的分布收入研究发现：中国股票市场是以分数布朗运动方式进行的，所形成的运动轨迹呈现出典型的α＜2的稳定帕雷托分布。因此，应该说，"分性市场假说"比"有效市场假说"更适用于中国股票市场。

The first stage is screen experiment. A 24-1 Fractional Factorial Design and resolution IV experiment is used to find out which main effect and interaction effect have obvious influence on the precision positioning of feeding table by these four factors. The Minitab program including Half Normal Plot, Pareto Chart, and ANOVA is applied to diagnose obvious effects. The second stage is optimization experiment. The fitness of regression model is obtained by using CCD of RSM with statistical hypothesis testing, regression analysis, lack-of-fit testing, and residual analysis. The optimum values can be found out by using response surface plot and contour plot.

在第一阶段为筛选实验采用24-1部分因子实验，解析度为IV，求出这4个因子主效应及交互作用哪些会对进给平台定位精度有显著的影响，在分析方面使用统计软体Minitab做初步分析，应用了半常态机率图、柏拉图与变异数分析来判断出显著因子与交互效应显著，第二阶段优化实验采用反应曲面法的中央合成设计，搭配统计检定、回归分析、缺适性检定(Lack-of-Fit)、残差分析来取决回归模式之合适性，最后根据反应曲面图及等高线图求出最佳值做验证实验。

However, if the steepness is set to a low value, it is easier to train an ANN that requires fractional output, like e.g., an ANN that should be trained to find the direction of a line in an image.

但是，如果陡峭设置为一个低价值，更容易培养的神经网络，需要小数输出，像例如，一个应接受培训，以找到一个图像中的人工神经网络的方向一致。
