A striking manifestation of the motion of particles in liquids was given for the first time by the so-called Brownian movement, a remarkable phenomenon which would remain quite mysterious and incomprehensible without the kinetic theory of matter.

所谓的布朗运动，首先给液体内粒子的运动作了一个令人信服的说明。这个奇异的现象，如果没有物质动理论，便会是完全神秘和不可理解的。

Boltzmann drew his conclusions of the already discovered Brownian molecular motion.

The non-conservative impulsive force that represents the chemical energy consumed in the conformation changing process is a crucial factor to the directed motion of the Brownian motors.

非保守脉冲力反映构象变化过程中消耗的化学能，是一个影响布朗粒子运动的重要因素。

Finally, fractal characteristic is researched in the thesis. Fractional Brownian motion characteristic of sea clutter is validated and fractal dimention of sea clutter without taget and sea clutter with target are calculated by box-dimention method.Target detection based on fractal dimention is analyzed in brief and sea clutter multi-fractal characteristic is analyzed by MF-DFA.

最后，本文对海杂波分形特性进行了研究，验证了海杂波符合分数布朗运动的特性，通过盒维数法计算纯海杂波和目标海杂波的分形维数，简要分析了基于单重分形维数的目标检测，并采用MF-DFA对海杂波多重分形特性进行了研究分析。

To make this market a complete one, we introduce the forward rate, which is driven by this Brownian motion, as a new risk factor, and under HJM model we have the new asset - zero-coupon bond. Then we can get the price of stock index futures by the martingale method.

为此引入受这个Brown运动影响的远期利率作为风险因子，在HJM模型框架下可化作新的风险资产——零息债券，得到虚拟的完全化市场后利用鞅方法解出股指期货价格表达式。

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。
