The Cu data appears to divide into a normal distribution for values below the first population upper limit 20 ppm for the fractal plot and one or more lognormal distributions above 20 ppm thresholds, which can identifies both the regions of Tertian basalts and main trend of Cu mineralization.

铜元素数据划分二个部分，一部分是元素含量少于20ppm的正态分布数据，另一部分是元素含量大于20ppm的多个对数正态分布数据，能识别第三纪玄武岩区域和铜的主要矿化区。这一结论与使用传统的概率图模型方法得到的结论一致。

In this paper, the main issue is about parameters involved with the stock's volatility, which are the σ in the Winner process and the λ and δ in the Poisson process, under the special cases of jump diffusion models with two assumptions that are independence between option prices' errors and stock and normal error between pricing formula and true price.

本论文在跳跃扩散模型中，以跳跃比例大小为非随机的常数或对数常态分配此种特例，和选择权价格的误差与股价过程为独立并且与理论公式存有常态误差值的两个假设下，去对模型中Winner过程里的σ以及Poisson过程里的λ和δ，这几个影响股价变异数的重要参数作讨论。

From the basic principles of the AC machine,using the equivalent analysis method, a series of the equations、vector diagram、equivalent circuits of BDFM were obtained, which is the foundation of the analysis and control of the BDFM wind power generation system. The variable structure control was first used to the active and reactive power decoupling control of the BDFM.

无刷双馈电机的功率绕组、控制绕组、转子绕组的极对数不同，电流的实际频率也各不相同，论文从交流电机的基本理论出发，采用等效的方法，得到了无刷双馈电机的基本方程式、向量图和等效电路。

The basic theory of this design is The Lambert Laws that the logarithm of the radio of the energy of a primal ray and the energy after this ray though a equable material is direct proportion with the thickness of the equable material,and so do the coefficient that the equable material absorpt with the ray.

理论基础是朗伯定律，即通过某一均匀截止前后光束的光能比的对数与介质的厚度成正比，与介质对光束的光能的吸收系数成正比。

For exponential distribution, the acquired estimate expression is the same as the result obtained by other method in reference [8]; for Weibull distribution, the author prove that γ satisfies a non-linear equation and λ is afunction of y; for lognormal distribution, a iterative algorithm for parameter estimation is proposed, which is the expansion of some results in Wolynetzs Ph.D. thesis.

对指数分布，得到的估计表达式与文献[8]中使用其他方法得到的结果相同；对Weibull分布，论文证明了参数γ满足一个非线性方程，而λ则可以直接由含有γ的表达式求出；对对数正态分布，论文给出参数估计的迭代算法，这可以看成是Wolynetz博士论文结果的推广。
